 * Patches by Pantelis Antoniou, 16 Apr 2004:
   - add support for a new version of an Intracom board and fix
     various other things on others.
   - add verify support to the crc32 command (define
     CONFIG_CRC32_VERIFY to enable it)
   - fix FEC driver for MPC8xx systems:
     1. fix compilation problems for boards that use dynamic
        allocation of DPRAM
     2. shut down FEC after network transfers
   - HUSH parser fixes:

        the one in the bourne shell.
     2. A new exit command was added which terminates the current
        executing script.

 * Patch by George G. Davis, 02 Apr 2004:
   add support for Intel Assabet board
 * Patch by Stephen Williams, 01 Apr 2004:
   Add support for Picture Elements JSE board
 * Patch by Christian Pell, 01 Apr 2004:
   Add CompactFlash support for PXA systems.
 * Patches by Pantelis Antoniou, 30 Mar 2004:
   - add auto-complete support to the U-Boot CLI
   - add support for NETTA and NETPHONE boards; fix NETVIA board
   - add support for the Epson 156x series of graphical displays
     (These displays are serial and not suitable for using a normal
     framebuffer console on them)
   - add infrastructure needed in order to POST any DSPs in a board
   - improve and fix various things in the MPC8xx FEC driver:
     1. The new 87x and 88x series of processors have two FECs,
        and the new driver supports them both.
     2. Another change in the 87x/88x series is support for
        the RMII (Reduced MII) interface. However numerous
        changes are needed to make it work since the PHYs
        are connected to the same lines. That means that
        you have to address them correctly over the MII
        interface.
     3. We now correctly match the MII/RMII interface
        configuration to what the PHY reports.
   - Fix problem when readingthe MII status register. Due to the
     internal design of many PHYs you have to read the register
     twice. The problem is more apparent in 10Mbit mode.
   - add new mode ".jffs2s" for reading from a NAND device: it just
     skips over bad blocks.
   - add networking support for VLANs (802.1q), and CDP (Cisco
     Discovery Protocol)
   - some minor patches / cleanup
 * Patch by Yuli Barcohen, 28 Mar 2004:
   - Add support for MPC8272 family including MPC8247/8248/8271/8272
   - Add support for MPC8272ADS evaluation board (another flavour of MPC8260ADS)
   - Change configuration method for MPC8260ADS family
 * add startup code to clear the BSS of standalone applications
 * Fix if / elif handling bug in HUSH shell

     config.mk to allow board configurations to override the GNU
     linker script, selected via the LDSCRIPT, make variable, and to
     give an initial value to the OBJCFLAGS make variable
   - 8260 i2c enhancement:
     o correctly extends the timeout depending on the size of all
       queued messages for both transmit and receive
     o will not continue with receive if transmit times out
     o ensures that the error callback is done for all queued tx
       and rx messages
     o correctly detects both tx and rx timeouts, only delivers one to
       the callback, and does not overwrite an earlier error
     o logic in i2c_probe now correct
   - add "vprintf()" function so that "panic()" function can be
     technically correct
   - many Hymod board changes

 Summary:
 ========
 This directory contains the source code for U-Boot, a boot loader for
 Embedded boards based on PowerPC and ARM processors, which can be
 installed in a boot ROM and used to initialize and test the hardware
 or to download and run application code.
 The development of U-Boot is closely related to Linux: some parts of
 the source code originate in the Linux source tree, we have some
 header files in common, and special provision has been made to
 support booting of Linux images.
 Some attention has been paid to make this software easily
 configurable and extendable. For instance, all monitor commands are
 implemented with the same call interface, so that it's very easy to
 add new commands. Also, instead of permanently adding rarely used
 code (for instance hardware test utilities) to the monitor, you can
 load and run it dynamically.
 Status:
 =======
 In general, all boards for which a configuration option exists in the
 Makefile have been tested to some extent and can be considered
 "working". In fact, many of them are used in production systems.
 In case of problems see the CHANGELOG and CREDITS files to find out
 who contributed the specific port.
 Where to get help:
 ==================
 In case you have questions about, problems with or contributions for
 U-Boot you should send a message to the U-Boot mailing list at
 <u-boot-users@lists.sourceforge.net>. There is also an archive of
 previous traffic on the mailing list - please search the archive
 before asking FAQ's. Please see
 http://lists.sourceforge.net/lists/listinfo/u-boot-users/
 Where we come from:
 ===================
 - start from 8xxrom sources
 - create PPCBoot project (http://sourceforge.net/projects/ppcboot)
 - clean up code
 - make it easier to add custom boards
 - make it possible to add other [PowerPC] CPUs
 - extend functions, especially:
   * Provide extended interface to Linux boot loader
   * S-Record download
   * network boot
   * PCMCIA / CompactFLash / ATA disk / SCSI ... boot
 - create ARMBoot project (http://sourceforge.net/projects/armboot)
 - add other CPU families (starting with ARM)
 - create U-Boot project (http://sourceforge.net/projects/u-boot)
 Names and Spelling:
 ===================
 The "official" name of this project is "Das U-Boot". The spelling
 "U-Boot" shall be used in all written text (documentation, comments
 in source files etc.). Example:
 	This is the README file for the U-Boot project.
 File names etc. shall be based on the string "u-boot". Examples:
 	include/asm-ppc/u-boot.h
 	#include <asm/u-boot.h>
 Variable names, preprocessor constants etc. shall be either based on
 the string "u_boot" or on "U_BOOT". Example:
 	U_BOOT_VERSION		u_boot_logo
 	IH_OS_U_BOOT		u_boot_hush_start
 Versioning:
 ===========
 U-Boot uses a 3 level version number containing a version, a
 sub-version, and a patchlevel: "U-Boot-2.34.5" means version "2",
 sub-version "34", and patchlevel "4".
 The patchlevel is used to indicate certain stages of development
 between released versions, i. e. officially released versions of
 U-Boot will always have a patchlevel of "0".

 Software Configuration:
 =======================
 Configuration is usually done using C preprocessor defines; the
 rationale behind that is to avoid dead code whenever possible.
 There are two classes of configuration variables:
 * Configuration _OPTIONS_:
   These are selectable by the user and have names beginning with
   "CONFIG_".
 * Configuration _SETTINGS_:
   These depend on the hardware etc. and should not be meddled with if
   you don't know what you're doing; they have names beginning with
   "CFG_".
 Later we will add a configuration tool - probably similar to or even
 identical to what's used for the Linux kernel. Right now, we have to
 do the configuration by hand, which means creating some symbolic
 links and editing some configuration files. We use the TQM8xxL boards
 as an example here.
 Selection of Processor Architecture and Board Type:
 ---------------------------------------------------
 For all supported boards there are ready-to-use default
 configurations available; just type "make <board_name>_config".
 Example: For a TQM823L module type:
 	cd u-boot
 	make TQM823L_config
 For the Cogent platform, you need to specify the cpu type as well;
 e.g. "make cogent_mpc8xx_config". And also configure the cogent
 directory according to the instructions in cogent/README.
 Configuration Options:
 ----------------------
 Configuration depends on the combination of board and CPU type; all
 such information is kept in a configuration file
 "include/configs/<board_name>.h".
 Example: For a TQM823L module, all configuration settings are in
 "include/configs/TQM823L.h".
 Many of the options are named exactly as the corresponding Linux
 kernel configuration options. The intention is to make it easier to
 build a config tool - later.
 The following options need to be configured:

 		CFG_866_OSCCLK
 		CFG_866_CPUCLK_MIN
 		CFG_866_CPUCLK_MAX
 		CFG_866_CPUCLK_DEFAULT
 			See doc/README.MPC866
 		CFG_MEASURE_CPUCLK
 		Define this to measure the actual CPU clock instead
 		of relying on the correctness of the configured
 		values. Mostly useful for board bringup to make sure
 		the PLL is locked at the intended frequency. Note
 		that this requires a (stable) reference clock (32 kHz
 		RTC clock),
 - Linux Kernel Interface:
 		CONFIG_CLOCKS_IN_MHZ
 		U-Boot stores all clock information in Hz
 		internally. For binary compatibility with older Linux
 		kernels (which expect the clocks passed in the
 		bd_info data to be in MHz) the environment variable
 		"clocks_in_mhz" can be defined so that U-Boot
 		converts clock data to MHZ before passing it to the
 		Linux kernel.
 		When CONFIG_CLOCKS_IN_MHZ is defined, a definition of
 		"clocks_in_mhz=1" is  automatically  included  in  the
 		default environment.
 		CONFIG_MEMSIZE_IN_BYTES		[relevant for MIPS only]
 		When transfering memsize parameter to linux, some versions
 		expect it to be in bytes, others in MB.
 		Define CONFIG_MEMSIZE_IN_BYTES to make it in bytes.
 - Console Interface:
 		Depending on board, define exactly one serial port
 		(like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2,
 		CONFIG_8xx_CONS_SCC1, ...), or switch off the serial
 		console by defining CONFIG_8xx_CONS_NONE
 		Note: if CONFIG_8xx_CONS_NONE is defined, the serial
 		port routines must be defined elsewhere
 		(i.e. serial_init(), serial_getc(), ...)
 		CONFIG_CFB_CONSOLE
 		Enables console device for a color framebuffer. Needs following
 		defines (cf. smiLynxEM, i8042, board/eltec/bab7xx)
 			VIDEO_FB_LITTLE_ENDIAN	graphic memory organisation
 						(default big endian)
 			VIDEO_HW_RECTFILL	graphic chip supports
 						rectangle fill
 						(cf. smiLynxEM)
 			VIDEO_HW_BITBLT		graphic chip supports
 						bit-blit (cf. smiLynxEM)
 			VIDEO_VISIBLE_COLS	visible pixel columns
 						(cols=pitch)
 			VIDEO_VISIBLE_ROWS	visible pixel rows
 			VIDEO_PIXEL_SIZE	bytes per pixel
 			VIDEO_DATA_FORMAT	graphic data format
 						(0-5, cf. cfb_console.c)
 			VIDEO_FB_ADRS		framebuffer address
 			VIDEO_KBD_INIT_FCT	keyboard int fct
 						(i.e. i8042_kbd_init())
 			VIDEO_TSTC_FCT		test char fct
 						(i.e. i8042_tstc)
 			VIDEO_GETC_FCT		get char fct
 						(i.e. i8042_getc)
 			CONFIG_CONSOLE_CURSOR	cursor drawing on/off
 						(requires blink timer
 						cf. i8042.c)
 			CFG_CONSOLE_BLINK_COUNT blink interval (cf. i8042.c)
 			CONFIG_CONSOLE_TIME	display time/date info in
 						upper right corner
 						(requires CFG_CMD_DATE)
 			CONFIG_VIDEO_LOGO	display Linux logo in
 						upper left corner
 			CONFIG_VIDEO_BMP_LOGO	use bmp_logo.h instead of
 						linux_logo.h for logo.
 						Requires CONFIG_VIDEO_LOGO
 			CONFIG_CONSOLE_EXTRA_INFO
 						addional board info beside
 						the logo
 		When CONFIG_CFB_CONSOLE is defined, video console is
 		default i/o. Serial console can be forced with
 		environment 'console=serial'.
 		When CONFIG_SILENT_CONSOLE is defined, all console
 		messages (by U-Boot and Linux!) can be silenced with
 		the "silent" environment variable. See
 		doc/README.silent for more information.
 - Console Baudrate:
 		CONFIG_BAUDRATE - in bps
 		Select one of the baudrates listed in
 		CFG_BAUDRATE_TABLE, see below.
 		CFG_BRGCLK_PRESCALE, baudrate prescale
 - Interrupt driven serial port input:
 		CONFIG_SERIAL_SOFTWARE_FIFO
 		PPC405GP only.
 		Use an interrupt handler for receiving data on the
 		serial port. It also enables using hardware handshake
 		(RTS/CTS) and UART's built-in FIFO. Set the number of
 		bytes the interrupt driven input buffer should have.
 		Leave undefined to disable this feature, including
 		disable the buffer and hardware handshake.
 - Console UART Number:
 		CONFIG_UART1_CONSOLE
 		IBM PPC4xx only.
 		If defined internal UART1 (and not UART0) is used
 		as default U-Boot console.
 - Boot Delay:	CONFIG_BOOTDELAY - in seconds
 		Delay before automatically booting the default image;
 		set to -1 to disable autoboot.
 		See doc/README.autoboot for these options that
 		work with CONFIG_BOOTDELAY. None are required.
 		CONFIG_BOOT_RETRY_TIME
 		CONFIG_BOOT_RETRY_MIN
 		CONFIG_AUTOBOOT_KEYED
 		CONFIG_AUTOBOOT_PROMPT
 		CONFIG_AUTOBOOT_DELAY_STR
 		CONFIG_AUTOBOOT_STOP_STR
 		CONFIG_AUTOBOOT_DELAY_STR2
 		CONFIG_AUTOBOOT_STOP_STR2
 		CONFIG_ZERO_BOOTDELAY_CHECK
 		CONFIG_RESET_TO_RETRY
 - Autoboot Command:
 		CONFIG_BOOTCOMMAND
 		Only needed when CONFIG_BOOTDELAY is enabled;
 		define a command string that is automatically executed
 		when no character is read on the console interface
 		within "Boot Delay" after reset.
 		CONFIG_BOOTARGS
 		This can be used to pass arguments to the bootm
 		command. The value of CONFIG_BOOTARGS goes into the
 		environment value "bootargs".
 		CONFIG_RAMBOOT and CONFIG_NFSBOOT
 		The value of these goes into the environment as
 		"ramboot" and "nfsboot" respectively, and can be used
 		as a convenience, when switching between booting from
 		ram and nfs.
 - Pre-Boot Commands:
 		CONFIG_PREBOOT
 		When this option is #defined, the existence of the
 		environment variable "preboot" will be checked
 		immediately before starting the CONFIG_BOOTDELAY
 		countdown and/or running the auto-boot command resp.
 		entering interactive mode.
 		This feature is especially useful when "preboot" is
 		automatically generated or modified. For an example
 		see the LWMON board specific code: here "preboot" is
 		modified when the user holds down a certain
 		combination of keys on the (special) keyboard when
 		booting the systems
 - Serial Download Echo Mode:
 		CONFIG_LOADS_ECHO
 		If defined to 1, all characters received during a
 		serial download (using the "loads" command) are
 		echoed back. This might be needed by some terminal
 		emulations (like "cu"), but may as well just take
 		time on others. This setting #define's the initial
 		value of the "loads_echo" environment variable.
 - Kgdb Serial Baudrate: (if CFG_CMD_KGDB is defined)
 		CONFIG_KGDB_BAUDRATE
 		Select one of the baudrates listed in
 		CFG_BAUDRATE_TABLE, see below.
 - Monitor Functions:
 		CONFIG_COMMANDS
 		Most monitor functions can be selected (or
 		de-selected) by adjusting the definition of
 		CONFIG_COMMANDS; to select individual functions,
 		#define CONFIG_COMMANDS by "OR"ing any of the
 		following values:
 		#define enables commands:

 		-----------------------------------------------
 		CFG_CMD_ALL	all
 		CFG_CMD_DFL	Default configuration; at the moment
 				this is includes all commands, except
 				the ones marked with "*" in the list
 				above.
 		If you don't define CONFIG_COMMANDS it defaults to
 		CFG_CMD_DFL in include/cmd_confdefs.h. A board can
 		override the default settings in the respective
 		include file.
 		EXAMPLE: If you want all functions except of network
 		support you can write:
 		#define CONFIG_COMMANDS (CFG_CMD_ALL & ~CFG_CMD_NET)
 	Note:	Don't enable the "icache" and "dcache" commands
 		(configuration option CFG_CMD_CACHE) unless you know
 		what you (and your U-Boot users) are doing. Data
 		cache cannot be enabled on systems like the 8xx or
 		8260 (where accesses to the IMMR region must be
 		uncached), and it cannot be disabled on all other
 		systems where we (mis-) use the data cache to hold an
 		initial stack and some data.
 		XXX - this list needs to get updated!
 - Watchdog:
 		CONFIG_WATCHDOG
 		If this variable is defined, it enables watchdog
 		support. There must be support in the platform specific
 		code for a watchdog. For the 8xx and 8260 CPUs, the
 		SIU Watchdog feature is enabled in the SYPCR
 		register.
 - U-Boot Version:
 		CONFIG_VERSION_VARIABLE
 		If this variable is defined, an environment variable
 		named "ver" is created by U-Boot showing the U-Boot
 		version as printed by the "version" command.
 		This variable is readonly.
 - Real-Time Clock:
 		When CFG_CMD_DATE is selected, the type of the RTC
 		has to be selected, too. Define exactly one of the
 		following options:
 		CONFIG_RTC_MPC8xx	- use internal RTC of MPC8xx
 		CONFIG_RTC_PCF8563	- use Philips PCF8563 RTC
 		CONFIG_RTC_MC146818	- use MC146818 RTC
 		CONFIG_RTC_DS1307	- use Maxim, Inc. DS1307 RTC
 		CONFIG_RTC_DS1337	- use Maxim, Inc. DS1337 RTC
 		CONFIG_RTC_DS1338	- use Maxim, Inc. DS1338 RTC
 		CONFIG_RTC_DS164x	- use Dallas DS164x RTC
+		CONFIG_RTC_MAX6900	- use Maxim, Inc. MAX6900 RTC
 		Note that if the RTC uses I2C, then the I2C interface
 		must also be configured. See I2C Support, below.
 - Timestamp Support:
 		When CONFIG_TIMESTAMP is selected, the timestamp
 		(date and time) of an image is printed by image
 		commands like bootm or iminfo. This option is
 		automatically enabled when you select CFG_CMD_DATE .
 - Partition Support:
 		CONFIG_MAC_PARTITION and/or CONFIG_DOS_PARTITION
 		and/or CONFIG_ISO_PARTITION
 		If IDE or SCSI support	is  enabled  (CFG_CMD_IDE  or
 		CFG_CMD_SCSI) you must configure support for at least
 		one partition type as well.
 - IDE Reset method:
 		CONFIG_IDE_RESET_ROUTINE - this is defined in several
 		board configurations files but used nowhere!
 		CONFIG_IDE_RESET - is this is defined, IDE Reset will
 		be performed by calling the function
 			ide_set_reset(int reset)
 		which has to be defined in a board specific file
 - ATAPI Support:
 		CONFIG_ATAPI
 		Set this to enable ATAPI support.
 - LBA48 Support
 		CONFIG_LBA48
 		Set this to enable support for disks larger than 137GB
 		Also look at CFG_64BIT_LBA ,CFG_64BIT_VSPRINTF and CFG_64BIT_STRTOUL
 		Whithout these , LBA48 support uses 32bit variables and will 'only'
 		support disks up to 2.1TB.
 		CFG_64BIT_LBA:
 			When enabled, makes the IDE subsystem use 64bit sector addresses.
 			Default is 32bit.
 - SCSI Support:
 		At the moment only there is only support for the
 		SYM53C8XX SCSI controller; define
 		CONFIG_SCSI_SYM53C8XX to enable it.
 		CFG_SCSI_MAX_LUN [8], CFG_SCSI_MAX_SCSI_ID [7] and
 		CFG_SCSI_MAX_DEVICE [CFG_SCSI_MAX_SCSI_ID *
 		CFG_SCSI_MAX_LUN] can be adjusted to define the
 		maximum numbers of LUNs, SCSI ID's and target
 		devices.
 		CFG_SCSI_SYM53C8XX_CCF to fix clock timing (80Mhz)
 - NETWORK Support (PCI):
 		CONFIG_E1000
 		Support for Intel 8254x gigabit chips.
 		CONFIG_EEPRO100
 		Support for Intel 82557/82559/82559ER chips.

 		write routine for first time initialisation.
 		CONFIG_TULIP
 		Support for Digital 2114x chips.
 		Optional CONFIG_TULIP_SELECT_MEDIA for board specific
 		modem chip initialisation (KS8761/QS6611).
 		CONFIG_NATSEMI
 		Support for National dp83815 chips.

 			of the device (I/O space)
 			CONFIG_SMC_USE_32_BIT
 			Define this if data bus is 32 bits
 			CONFIG_SMC_USE_IOFUNCS
 			Define this to use i/o functions instead of macros
 			(some hardware wont work with macros)
 - USB Support:
 		At the moment only the UHCI host controller is
 		supported (PIP405, MIP405, MPC5200); define
 		CONFIG_USB_UHCI to enable it.
 		define CONFIG_USB_KEYBOARD to enable the USB Keyboard
 		end define CONFIG_USB_STORAGE to enable the USB
 		storage devices.
 		Note:
 		Supported are USB Keyboards and USB Floppy drives
 		(TEAC FD-05PUB).
 		MPC5200 USB requires additional defines:
 			CONFIG_USB_CLOCK
 				for 528 MHz Clock: 0x0001bbbb
 			CONFIG_USB_CONFIG
 				for differential drivers: 0x00001000
 				for single ended drivers: 0x00005000
 - MMC Support:
 		The MMC controller on the Intel PXA is supported. To
 		enable this define CONFIG_MMC. The MMC can be
 		accessed from the boot prompt by mapping the device
 		to physical memory similar to flash. Command line is
 		enabled with CFG_CMD_MMC. The MMC driver also works with
 		the FAT fs. This is enabled with CFG_CMD_FAT.
 - Keyboard Support:
 		CONFIG_ISA_KEYBOARD
 		Define this to enable standard (PC-Style) keyboard
 		support
 		CONFIG_I8042_KBD
 		Standard PC keyboard driver with US (is default) and
 		GERMAN key layout (switch via environment 'keymap=de') support.
 		Export function i8042_kbd_init, i8042_tstc and i8042_getc
 		for cfb_console. Supports cursor blinking.
 - Video support:
 		CONFIG_VIDEO
 		Define this to enable video support (for output to
 		video).
 		CONFIG_VIDEO_CT69000
 		Enable Chips & Technologies 69000 Video chip
 		CONFIG_VIDEO_SMI_LYNXEM
 		Enable Silicon Motion SMI 712/710/810 Video chip. The
 		video output is selected via environment 'videoout'
 		(1 = LCD and 2 = CRT). If videoout is undefined, CRT is
 		assumed.
 		For the CT69000 and SMI_LYNXEM drivers, videomode is
 		selected via environment 'videomode'. Two diferent ways
 		are possible:
 		- "videomode=num"   'num' is a standard LiLo mode numbers.
 		Following standard modes are supported	(* is default):
 		      Colors	640x480 800x600 1024x768 1152x864 1280x1024
 		-------------+---------------------------------------------
 		      8 bits |	0x301*	0x303	 0x305	  0x161	    0x307
 		     15 bits |	0x310	0x313	 0x316	  0x162	    0x319
 		     16 bits |	0x311	0x314	 0x317	  0x163	    0x31A
 		     24 bits |	0x312	0x315	 0x318	    ?	    0x31B
 		-------------+---------------------------------------------
 		(i.e. setenv videomode 317; saveenv; reset;)
 		- "videomode=bootargs" all the video parameters are parsed
 		from the bootargs. (See drivers/videomodes.c)
 		CONFIG_VIDEO_SED13806
 		Enable Epson SED13806 driver. This driver supports 8bpp
 		and 16bpp modes defined by CONFIG_VIDEO_SED13806_8BPP
 		or CONFIG_VIDEO_SED13806_16BPP
 - Keyboard Support:
 		CONFIG_KEYBOARD
 		Define this to enable a custom keyboard support.
 		This simply calls drv_keyboard_init() which must be
 		defined in your board-specific files.
 		The only board using this so far is RBC823.
 - LCD Support:	CONFIG_LCD
 		Define this to enable LCD support (for output to LCD
 		display); also select one of the supported displays
 		by defining one of these:
 		CONFIG_NEC_NL6448AC33:
 			NEC NL6448AC33-18. Active, color, single scan.
 		CONFIG_NEC_NL6448BC20
 			NEC NL6448BC20-08. 6.5", 640x480.
 			Active, color, single scan.
 		CONFIG_NEC_NL6448BC33_54
 			NEC NL6448BC33-54. 10.4", 640x480.
 			Active, color, single scan.
 		CONFIG_SHARP_16x9
 			Sharp 320x240. Active, color, single scan.
 			It isn't 16x9, and I am not sure what it is.
 		CONFIG_SHARP_LQ64D341
 			Sharp LQ64D341 display, 640x480.
 			Active, color, single scan.
 		CONFIG_HLD1045
 			HLD1045 display, 640x480.
 			Active, color, single scan.
 		CONFIG_OPTREX_BW
 			Optrex	 CBL50840-2 NF-FW 99 22 M5
 			or
 			Hitachi	 LMG6912RPFC-00T
 			or
 			Hitachi	 SP14Q002
 			320x240. Black & white.
 		Normally display is black on white background; define
 		CFG_WHITE_ON_BLACK to get it inverted.
 - Splash Screen Support: CONFIG_SPLASH_SCREEN
 		If this option is set, the environment is checked for
 		a variable "splashimage". If found, the usual display
 		of logo, copyright and system information on the LCD
 		is supressed and the BMP image at the address
 		specified in "splashimage" is loaded instead. The
 		console is redirected to the "nulldev", too. This
 		allows for a "silent" boot where a splash screen is
 		loaded very quickly after power-on.
 - Compression support:
 		CONFIG_BZIP2
 		If this option is set, support for bzip2 compressed
 		images is included. If not, only uncompressed and gzip
 		compressed images are supported.
 		NOTE: the bzip2 algorithm requires a lot of RAM, so
 		the malloc area (as defined by CFG_MALLOC_LEN) should
 		be at least 4MB.
 - MII/PHY support:
 		CONFIG_PHY_ADDR
 		The address of PHY on MII bus.
 		CONFIG_PHY_CLOCK_FREQ (ppc4xx)
 		The clock frequency of the MII bus
 		CONFIG_PHY_GIGE
 		If this option is set, support for speed/duplex
 		detection of Gigabit PHY is included.
 		CONFIG_PHY_RESET_DELAY
 		Some PHY like Intel LXT971A need extra delay after
 		reset before any MII register access is possible.
 		For such PHY, set this option to the usec delay
 		required. (minimum 300usec for LXT971A)
 		CONFIG_PHY_CMD_DELAY (ppc4xx)
 		Some PHY like Intel LXT971A need extra delay after
 		command issued before MII status register can be read
 - Ethernet address:
 		CONFIG_ETHADDR
 		CONFIG_ETH2ADDR
 		CONFIG_ETH3ADDR
 		Define a default value for ethernet address to use
 		for the respective ethernet interface, in case this
 		is not determined automatically.
 - IP address:
 		CONFIG_IPADDR
 		Define a default value for the IP address to use for
 		the default ethernet interface, in case this is not
 		determined through e.g. bootp.
 - Server IP address:
 		CONFIG_SERVERIP
 		Defines a default value for theIP address of a TFTP
 		server to contact when using the "tftboot" command.
 - BOOTP Recovery Mode:
 		CONFIG_BOOTP_RANDOM_DELAY
 		If you have many targets in a network that try to
 		boot using BOOTP, you may want to avoid that all
 		systems send out BOOTP requests at precisely the same
 		moment (which would happen for instance at recovery
 		from a power failure, when all systems will try to
 		boot, thus flooding the BOOTP server. Defining
 		CONFIG_BOOTP_RANDOM_DELAY causes a random delay to be
 		inserted before sending out BOOTP requests. The
 		following delays are insterted then:
 		1st BOOTP request:	delay 0 ... 1 sec
 		2nd BOOTP request:	delay 0 ... 2 sec
 		3rd BOOTP request:	delay 0 ... 4 sec
 		4th and following
 		BOOTP requests:		delay 0 ... 8 sec
 - DHCP Advanced Options:
 		CONFIG_BOOTP_MASK
 		You can fine tune the DHCP functionality by adding
 		these flags to the CONFIG_BOOTP_MASK define:
 		CONFIG_BOOTP_DNS2 - If a DHCP client requests the DNS
 		serverip from a DHCP server, it is possible that more
 		than one DNS serverip is offered to the client.
 		If CONFIG_BOOTP_DNS2 is enabled, the secondary DNS
 		serverip will be stored in the additional environment
 		variable "dnsip2". The first DNS serverip is always
 		stored in the variable "dnsip", when CONFIG_BOOTP_DNS
 		is added to the CONFIG_BOOTP_MASK.
 		CONFIG_BOOTP_SEND_HOSTNAME - Some DHCP servers are capable
 		to do a dynamic update of a DNS server. To do this, they
 		need the hostname of the DHCP requester.
 		If CONFIG_BOOP_SEND_HOSTNAME is added to the
 		CONFIG_BOOTP_MASK, the content of the "hostname"
 		environment variable is passed as option 12 to
 		the DHCP server.
  - CDP Options:
 		CONFIG_CDP_DEVICE_ID
 		The device id used in CDP trigger frames.
 		CONFIG_CDP_DEVICE_ID_PREFIX
 		A two character string which is prefixed to the MAC address
 		of the device.
 		CONFIG_CDP_PORT_ID
 		A printf format string which contains the ascii name of
 		the port. Normally is set to "eth%d" which sets
 		eth0 for the first ethernet, eth1 for the second etc.
 		CONFIG_CDP_CAPABILITIES
 		A 32bit integer which indicates the device capabilities;
 		0x00000010 for a normal host which does not forwards.
 		CONFIG_CDP_VERSION
 		An ascii string containing the version of the software.
 		CONFIG_CDP_PLATFORM
 		An ascii string containing the name of the platform.
 		CONFIG_CDP_TRIGGER
 		A 32bit integer sent on the trigger.
 		CONFIG_CDP_POWER_CONSUMPTION
 		A 16bit integer containing the power consumption of the
 		device in .1 of milliwatts.
 		CONFIG_CDP_APPLIANCE_VLAN_TYPE
 		A byte containing the id of the VLAN.
 - Status LED:	CONFIG_STATUS_LED
 		Several configurations allow to display the current
 		status using a LED. For instance, the LED will blink
 		fast while running U-Boot code, stop blinking as
 		soon as a reply to a BOOTP request was received, and
 		start blinking slow once the Linux kernel is running
 		(supported by a status LED driver in the Linux
 		kernel). Defining CONFIG_STATUS_LED enables this
 		feature in U-Boot.
 - CAN Support:	CONFIG_CAN_DRIVER
 		Defining CONFIG_CAN_DRIVER enables CAN driver support
 		on those systems that support this (optional)
 		feature, like the TQM8xxL modules.
 - I2C Support:	CONFIG_HARD_I2C | CONFIG_SOFT_I2C
 		These enable I2C serial bus commands. Defining either of
 		(but not both of) CONFIG_HARD_I2C or CONFIG_SOFT_I2C will
 		include the appropriate I2C driver for the selected cpu.
 		This will allow you to use i2c commands at the u-boot
 		command line (as long as you set CFG_CMD_I2C in
 		CONFIG_COMMANDS) and communicate with i2c based realtime
 		clock chips. See common/cmd_i2c.c for a description of the
 		command line interface.
 		CONFIG_HARD_I2C selects the CPM hardware driver for I2C.
 		CONFIG_SOFT_I2C configures u-boot to use a software (aka
 		bit-banging) driver instead of CPM or similar hardware
 		support for I2C.
 		There are several other quantities that must also be
 		defined when you define CONFIG_HARD_I2C or CONFIG_SOFT_I2C.
 		In both cases you will need to define CFG_I2C_SPEED
 		to be the frequency (in Hz) at which you wish your i2c bus
 		to run and CFG_I2C_SLAVE to be the address of this node (ie
 		the cpu's i2c node address).
 		Now, the u-boot i2c code for the mpc8xx (cpu/mpc8xx/i2c.c)
 		sets the cpu up as a master node and so its address should
 		therefore be cleared to 0 (See, eg, MPC823e User's Manual
 		p.16-473). So, set CFG_I2C_SLAVE to 0.
 		That's all that's required for CONFIG_HARD_I2C.
 		If you use the software i2c interface (CONFIG_SOFT_I2C)
 		then the following macros need to be defined (examples are
 		from include/configs/lwmon.h):
 		I2C_INIT
 		(Optional). Any commands necessary to enable the I2C
 		controller or configure ports.
 		eg: #define I2C_INIT (immr->im_cpm.cp_pbdir |=	PB_SCL)
 		I2C_PORT
 		(Only for MPC8260 CPU). The I/O port to use (the code
 		assumes both bits are on the same port). Valid values
 		are 0..3 for ports A..D.
 		I2C_ACTIVE
 		The code necessary to make the I2C data line active
 		(driven).  If the data line is open collector, this
 		define can be null.
 		eg: #define I2C_ACTIVE (immr->im_cpm.cp_pbdir |=  PB_SDA)
 		I2C_TRISTATE
 		The code necessary to make the I2C data line tri-stated
 		(inactive).  If the data line is open collector, this
 		define can be null.
 		eg: #define I2C_TRISTATE (immr->im_cpm.cp_pbdir &= ~PB_SDA)
 		I2C_READ
 		Code that returns TRUE if the I2C data line is high,
 		FALSE if it is low.
 		eg: #define I2C_READ ((immr->im_cpm.cp_pbdat & PB_SDA) != 0)
 		I2C_SDA(bit)
 		If <bit> is TRUE, sets the I2C data line high. If it
 		is FALSE, it clears it (low).
 		eg: #define I2C_SDA(bit) \
 			if(bit) immr->im_cpm.cp_pbdat |=  PB_SDA; \
 			else	immr->im_cpm.cp_pbdat &= ~PB_SDA
 		I2C_SCL(bit)
 		If <bit> is TRUE, sets the I2C clock line high. If it
 		is FALSE, it clears it (low).
 		eg: #define I2C_SCL(bit) \
 			if(bit) immr->im_cpm.cp_pbdat |=  PB_SCL; \
 			else	immr->im_cpm.cp_pbdat &= ~PB_SCL
 		I2C_DELAY
 		This delay is invoked four times per clock cycle so this
 		controls the rate of data transfer.  The data rate thus
 		is 1 / (I2C_DELAY * 4). Often defined to be something
 		like:
 		#define I2C_DELAY  udelay(2)
 		CFG_I2C_INIT_BOARD
 		When a board is reset during an i2c bus transfer
 		chips might think that the current transfer is still
 		in progress. On some boards it is possible to access
 		the i2c SCLK line directly, either by using the
 		processor pin as a GPIO or by having a second pin
 		connected to the bus. If this option is defined a
 		custom i2c_init_board() routine in boards/xxx/board.c
 		is run early in the boot sequence.
 		CONFIG_I2CFAST (PPC405GP|PPC405EP only)
 		This option enables configuration of bi_iic_fast[] flags
 		in u-boot bd_info structure based on u-boot environment
 		variable "i2cfast". (see also i2cfast)
 - SPI Support:	CONFIG_SPI
 		Enables SPI driver (so far only tested with
 		SPI EEPROM, also an instance works with Crystal A/D and
 		D/As on the SACSng board)
 		CONFIG_SPI_X
 		Enables extended (16-bit) SPI EEPROM addressing.
 		(symmetrical to CONFIG_I2C_X)
 		CONFIG_SOFT_SPI
 		Enables a software (bit-bang) SPI driver rather than
 		using hardware support. This is a general purpose
 		driver that only requires three general I/O port pins
 		(two outputs, one input) to function. If this is
 		defined, the board configuration must define several
 		SPI configuration items (port pins to use, etc). For
 		an example, see include/configs/sacsng.h.
 - FPGA Support: CONFIG_FPGA_COUNT
 		Specify the number of FPGA devices to support.
 		CONFIG_FPGA
 		Used to specify the types of FPGA devices.  For example,
 		#define CONFIG_FPGA  CFG_XILINX_VIRTEX2
 		CFG_FPGA_PROG_FEEDBACK
 		Enable printing of hash marks during FPGA configuration.
 		CFG_FPGA_CHECK_BUSY
 		Enable checks on FPGA configuration interface busy
 		status by the configuration function. This option
 		will require a board or device specific function to
 		be written.
 		CONFIG_FPGA_DELAY
 		If defined, a function that provides delays in the FPGA
 		configuration driver.
 		CFG_FPGA_CHECK_CTRLC
 		Allow Control-C to interrupt FPGA configuration
 		CFG_FPGA_CHECK_ERROR
 		Check for configuration errors during FPGA bitfile
 		loading. For example, abort during Virtex II
 		configuration if the INIT_B line goes low (which
 		indicated a CRC error).
 		CFG_FPGA_WAIT_INIT
 		Maximum time to wait for the INIT_B line to deassert
 		after PROB_B has been deasserted during a Virtex II
 		FPGA configuration sequence. The default time is 500
 		mS.
 		CFG_FPGA_WAIT_BUSY
 		Maximum time to wait for BUSY to deassert during
 		Virtex II FPGA configuration. The default is 5 mS.
 		CFG_FPGA_WAIT_CONFIG
 		Time to wait after FPGA configuration. The default is
 		200 mS.
 - Configuration Management:
 		CONFIG_IDENT_STRING
 		If defined, this string will be added to the U-Boot
 		version information (U_BOOT_VERSION)
 - Vendor Parameter Protection:
 		U-Boot considers the values of the environment
 		variables "serial#" (Board Serial Number) and
 		"ethaddr" (Ethernet Address) to be parameters that
 		are set once by the board vendor / manufacturer, and
 		protects these variables from casual modification by
 		the user. Once set, these variables are read-only,
 		and write or delete attempts are rejected. You can
 		change this behviour:
 		If CONFIG_ENV_OVERWRITE is #defined in your config
 		file, the write protection for vendor parameters is
 		completely disabled. Anybody can change or delete
 		these parameters.
 		Alternatively, if you #define _both_ CONFIG_ETHADDR
 		_and_ CONFIG_OVERWRITE_ETHADDR_ONCE, a default
 		ethernet address is installed in the environment,
 		which can be changed exactly ONCE by the user. [The
 		serial# is unaffected by this, i. e. it remains
 		read-only.]
 - Protected RAM:
 		CONFIG_PRAM
 		Define this variable to enable the reservation of
 		"protected RAM", i. e. RAM which is not overwritten
 		by U-Boot. Define CONFIG_PRAM to hold the number of
 		kB you want to reserve for pRAM. You can overwrite
 		this default value by defining an environment
 		variable "pram" to the number of kB you want to
 		reserve. Note that the board info structure will
 		still show the full amount of RAM. If pRAM is
 		reserved, a new environment variable "mem" will
 		automatically be defined to hold the amount of
 		remaining RAM in a form that can be passed as boot
 		argument to Linux, for instance like that:
 			setenv bootargs ... mem=\$(mem)
 			saveenv
 		This way you can tell Linux not to use this memory,
 		either, which results in a memory region that will
 		not be affected by reboots.
 		*WARNING* If your board configuration uses automatic
 		detection of the RAM size, you must make sure that
 		this memory test is non-destructive. So far, the
 		following board configurations are known to be
 		"pRAM-clean":
 			ETX094, IVMS8, IVML24, SPD8xx, TQM8xxL,
 			HERMES, IP860, RPXlite, LWMON, LANTEC,
 			PCU_E, FLAGADM, TQM8260
 - Error Recovery:
 		CONFIG_PANIC_HANG
 		Define this variable to stop the system in case of a
 		fatal error, so that you have to reset it manually.
 		This is probably NOT a good idea for an embedded
 		system where you want to system to reboot
 		automatically as fast as possible, but it may be
 		useful during development since you can try to debug
 		the conditions that lead to the situation.
 		CONFIG_NET_RETRY_COUNT
 		This variable defines the number of retries for
 		network operations like ARP, RARP, TFTP, or BOOTP
 		before giving up the operation. If not defined, a
 		default value of 5 is used.
 - Command Interpreter:
 		CFG_AUTO_COMPLETE
 		Enable auto completion of commands using TAB.
 		CFG_HUSH_PARSER
 		Define this variable to enable the "hush" shell (from
 		Busybox) as command line interpreter, thus enabling
 		powerful command line syntax like
 		if...then...else...fi conditionals or `&&' and '||'
 		constructs ("shell scripts").
 		If undefined, you get the old, much simpler behaviour
 		with a somewhat smaller memory footprint.
 		CFG_PROMPT_HUSH_PS2
 		This defines the secondary prompt string, which is
 		printed when the command interpreter needs more input
 		to complete a command. Usually "> ".
 	Note:
 		In the current implementation, the local variables
 		space and global environment variables space are
 		separated. Local variables are those you define by
 		simply typing `name=value'. To access a local
 		variable later on, you have write `$name' or
 		`${name}'; to execute the contents of a variable
 		directly type `$name' at the command prompt.
 		Global environment variables are those you use
 		setenv/printenv to work with. To run a command stored
 		in such a variable, you need to use the run command,
 		and you must not use the '$' sign to access them.
 		To store commands and special characters in a
 		variable, please use double quotation marks
 		surrounding the whole text of the variable, instead
 		of the backslashes before semicolons and special
 		symbols.
 - Default Environment:
 		CONFIG_EXTRA_ENV_SETTINGS
 		Define this to contain any number of null terminated
 		strings (variable = value pairs) that will be part of
 		the default environment compiled into the boot image.
 		For example, place something like this in your
 		board's config file:
 		#define CONFIG_EXTRA_ENV_SETTINGS \
 			"myvar1=value1\0" \
 			"myvar2=value2\0"
 		Warning: This method is based on knowledge about the
 		internal format how the environment is stored by the
 		U-Boot code. This is NOT an official, exported
 		interface! Although it is unlikely that this format
 		will change soon, there is no guarantee either.
 		You better know what you are doing here.
 		Note: overly (ab)use of the default environment is
 		discouraged. Make sure to check other ways to preset
 		the environment like the autoscript function or the
 		boot command first.
 - DataFlash Support:
 		CONFIG_HAS_DATAFLASH
 		Defining this option enables DataFlash features and
 		allows to read/write in Dataflash via the standard
 		commands cp, md...
 - SystemACE Support:
 		CONFIG_SYSTEMACE
 		Adding this option adds support for Xilinx SystemACE
 		chips attached via some sort of local bus. The address
 		of the chip must alsh be defined in the
 		CFG_SYSTEMACE_BASE macro. For example:
 		#define CONFIG_SYSTEMACE
 		#define CFG_SYSTEMACE_BASE 0xf0000000
 		When SystemACE support is added, the "ace" device type
 		becomes available to the fat commands, i.e. fatls.
 - Show boot progress:
 		CONFIG_SHOW_BOOT_PROGRESS
 		Defining this option allows to add some board-
 		specific code (calling a user-provided function
 		"show_boot_progress(int)") that enables you to show
 		the system's boot progress on some display (for
 		example, some LED's) on your board. At the moment,
 		the following checkpoints are implemented:

 Modem Support:
 --------------
 [so far only for SMDK2400 and TRAB boards]
 - Modem support endable:
 		CONFIG_MODEM_SUPPORT
 - RTS/CTS Flow control enable:
 		CONFIG_HWFLOW
 - Modem debug support:
 		CONFIG_MODEM_SUPPORT_DEBUG
 		Enables debugging stuff (char screen[1024], dbg())
 		for modem support. Useful only with BDI2000.
 - Interrupt support (PPC):
 		There are common interrupt_init() and timer_interrupt()
 		for all PPC archs. interrupt_init() calls interrupt_init_cpu()
 		for cpu specific initialization. interrupt_init_cpu()
 		should set decrementer_count to appropriate value. If
 		cpu resets decrementer automatically after interrupt
 		(ppc4xx) it should set decrementer_count to zero.
 		timer_interrupt() calls timer_interrupt_cpu() for cpu
 		specific handling. If board has watchdog / status_led
 		/ other_activity_monitor it works automatically from
 		general timer_interrupt().
 - General:
 		In the target system modem support is enabled when a
 		specific key (key combination) is pressed during
 		power-on. Otherwise U-Boot will boot normally
 		(autoboot). The key_pressed() fuction is called from
 		board_init(). Currently key_pressed() is a dummy
 		function, returning 1 and thus enabling modem
 		initialization.
 		If there are no modem init strings in the
 		environment, U-Boot proceed to autoboot; the
 		previous output (banner, info printfs) will be
 		supressed, though.
 		See also: doc/README.Modem
 Configuration Settings:
 -----------------------

 		the application (usually a Linux kernel) when it is
 		booted
 - CFG_BAUDRATE_TABLE:
 		List of legal baudrate settings for this board.
 - CFG_CONSOLE_INFO_QUIET
 		Suppress display of console information at boot.
 - CFG_CONSOLE_IS_IN_ENV
 		If the board specific function
 			extern int overwrite_console (void);
 		returns 1, the stdin, stderr and stdout are switched to the
 		serial port, else the settings in the environment are used.
 - CFG_CONSOLE_OVERWRITE_ROUTINE
 		Enable the call to overwrite_console().
 - CFG_CONSOLE_ENV_OVERWRITE
 		Enable overwrite of previous console environment settings.

 		Begin and End addresses of the area used by the
 		simple memory test.
 - CFG_ALT_MEMTEST:
 		Enable an alternate, more extensive memory test.
 - CFG_MEMTEST_SCRATCH:
 		Scratch address used by the alternate memory test
 		You only need to set this if address zero isn't writeable
 - CFG_TFTP_LOADADDR:
 		Default load address for network file downloads
 - CFG_LOADS_BAUD_CHANGE:
 		Enable temporary baudrate change while serial download
 - CFG_SDRAM_BASE:
 		Physical start address of SDRAM. _Must_ be 0 here.
 - CFG_MBIO_BASE:
 		Physical start address of Motherboard I/O (if using a
 		Cogent motherboard)
 - CFG_FLASH_BASE:
 		Physical start address of Flash memory.
 - CFG_MONITOR_BASE:
 		Physical start address of boot monitor code (set by
 		make config files to be same as the text base address
 		(TEXT_BASE) used when linking) - same as
 		CFG_FLASH_BASE when booting from flash.
 - CFG_MONITOR_LEN:
 		Size of memory reserved for monitor code, used to
 		determine _at_compile_time_ (!) if the environment is
 		embedded within the U-Boot image, or in a separate
 		flash sector.
 - CFG_MALLOC_LEN:
 		Size of DRAM reserved for malloc() use.

 		without this option such a download has to be
 		performed in two steps: (1) download to RAM, and (2)
 		copy from RAM to flash.
 		The two-step approach is usually more reliable, since
 		you can check if the download worked before you erase
 		the flash, but in some situations (when sytem RAM is
 		too limited to allow for a tempory copy of the
 		downloaded image) this option may be very useful.
 - CFG_FLASH_CFI:
 		Define if the flash driver uses extra elements in the
 		common flash structure for storing flash geometry.
 - CFG_FLASH_CFI_DRIVER
 		This option also enables the building of the cfi_flash driver
 		in the drivers directory
 - CFG_RX_ETH_BUFFER:
 		Defines the number of ethernet receive buffers. On some
 		ethernet controllers it is recommended to set this value
 		to 8 or even higher (EEPRO100 or 405 EMAC), since all
 		buffers can be full shortly after enabling the interface
 		on high ethernet traffic.
 		Defaults to 4 if not defined.
 The following definitions that deal with the placement and management
 of environment data (variable area); in general, we support the
 following configurations:
 - CFG_ENV_IS_IN_FLASH:
 	Define this if the environment is in flash memory.
 	a) The environment occupies one whole flash sector, which is
 	   "embedded" in the text segment with the U-Boot code. This
 	   happens usually with "bottom boot sector" or "top boot
 	   sector" type flash chips, which have several smaller
 	   sectors at the start or the end. For instance, such a
 	   layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
 	   such a case you would place the environment in one of the
 	   4 kB sectors - with U-Boot code before and after it. With
 	   "top boot sector" type flash chips, you would put the
 	   environment in one of the last sectors, leaving a gap
 	   between U-Boot and the environment.
 	- CFG_ENV_OFFSET:
 	   Offset of environment data (variable area) to the
 	   beginning of flash memory; for instance, with bottom boot
 	   type flash chips the second sector can be used: the offset
 	   for this sector is given here.
 	   CFG_ENV_OFFSET is used relative to CFG_FLASH_BASE.
 	- CFG_ENV_ADDR:
 	   This is just another way to specify the start address of
 	   the flash sector containing the environment (instead of
 	   CFG_ENV_OFFSET).
 	- CFG_ENV_SECT_SIZE:
 	   Size of the sector containing the environment.
 	b) Sometimes flash chips have few, equal sized, BIG sectors.
 	   In such a case you don't want to spend a whole sector for
 	   the environment.
 	- CFG_ENV_SIZE:
 	   If you use this in combination with CFG_ENV_IS_IN_FLASH
 	   and CFG_ENV_SECT_SIZE, you can specify to use only a part
 	   of this flash sector for the environment. This saves
 	   memory for the RAM copy of the environment.
 	   It may also save flash memory if you decide to use this
 	   when your environment is "embedded" within U-Boot code,
 	   since then the remainder of the flash sector could be used
 	   for U-Boot code. It should be pointed out that this is
 	   STRONGLY DISCOURAGED from a robustness point of view:
 	   updating the environment in flash makes it always
 	   necessary to erase the WHOLE sector. If something goes
 	   wrong before the contents has been restored from a copy in
 	   RAM, your target system will be dead.
 	- CFG_ENV_ADDR_REDUND
 	  CFG_ENV_SIZE_REDUND
 	   These settings describe a second storage area used to hold
 	   a redundand copy of the environment data, so that there is
 	   a valid backup copy in case there is a power failure during
 	   a "saveenv" operation.
 BE CAREFUL! Any changes to the flash layout, and some changes to the
 source code will make it necessary to adapt <board>/u-boot.lds*
 accordingly!
 - CFG_ENV_IS_IN_NVRAM:
 	Define this if you have some non-volatile memory device
 	(NVRAM, battery buffered SRAM) which you want to use for the
 	environment.
 	- CFG_ENV_ADDR:
 	- CFG_ENV_SIZE:
 	  These two #defines are used to determin the memory area you
 	  want to use for environment. It is assumed that this memory
 	  can just be read and written to, without any special
 	  provision.
 BE CAREFUL! The first access to the environment happens quite early
 in U-Boot initalization (when we try to get the setting of for the
 console baudrate). You *MUST* have mappend your NVRAM area then, or
 U-Boot will hang.
 Please note that even with NVRAM we still use a copy of the
 environment in RAM: we could work on NVRAM directly, but we want to
 keep settings there always unmodified except somebody uses "saveenv"
 to save the current settings.
 - CFG_ENV_IS_IN_EEPROM:
 	Use this if you have an EEPROM or similar serial access
 	device and a driver for it.
 	- CFG_ENV_OFFSET:
 	- CFG_ENV_SIZE:
 	  These two #defines specify the offset and size of the
 	  environment area within the total memory of your EEPROM.
 	- CFG_I2C_EEPROM_ADDR:
 	  If defined, specified the chip address of the EEPROM device.
 	  The default address is zero.
 	- CFG_EEPROM_PAGE_WRITE_BITS:
 	  If defined, the number of bits used to address bytes in a
 	  single page in the EEPROM device.  A 64 byte page, for example
 	  would require six bits.
 	- CFG_EEPROM_PAGE_WRITE_DELAY_MS:
 	  If defined, the number of milliseconds to delay between
 	  page writes.	The default is zero milliseconds.
 	- CFG_I2C_EEPROM_ADDR_LEN:
 	  The length in bytes of the EEPROM memory array address.  Note
 	  that this is NOT the chip address length!
 	- CFG_I2C_EEPROM_ADDR_OVERFLOW:
 	  EEPROM chips that implement "address overflow" are ones
 	  like Catalyst 24WC04/08/16 which has 9/10/11 bits of
 	  address and the extra bits end up in the "chip address" bit
 	  slots. This makes a 24WC08 (1Kbyte) chip look like four 256
 	  byte chips.
 	  Note that we consider the length of the address field to
 	  still be one byte because the extra address bits are hidden
 	  in the chip address.
 	- CFG_EEPROM_SIZE:
 	  The size in bytes of the EEPROM device.
 - CFG_ENV_IS_IN_DATAFLASH:
 	Define this if you have a DataFlash memory device which you
 	want to use for the environment.
 	- CFG_ENV_OFFSET:
 	- CFG_ENV_ADDR:
 	- CFG_ENV_SIZE:
 	  These three #defines specify the offset and size of the
 	  environment area within the total memory of your DataFlash placed
 	  at the specified address.
 - CFG_ENV_IS_IN_NAND:
 	Define this if you have a NAND device which you want to use
 	for the environment.
 	- CFG_ENV_OFFSET:
 	- CFG_ENV_SIZE:
 	  These two #defines specify the offset and size of the environment
 	  area within the first NAND device.
 - CFG_SPI_INIT_OFFSET
 	Defines offset to the initial SPI buffer area in DPRAM. The
 	area is used at an early stage (ROM part) if the environment
 	is configured to reside in the SPI EEPROM: We need a 520 byte
 	scratch DPRAM area. It is used between the two initialization
 	calls (spi_init_f() and spi_init_r()). A value of 0xB00 seems
 	to be a good choice since it makes it far enough from the
 	start of the data area as well as from the stack pointer.
 Please note that the environment is read-only as long as the monitor
 has been relocated to RAM and a RAM copy of the environment has been
 created; also, when using EEPROM you will have to use getenv_r()
 until then to read environment variables.
 The environment is protected by a CRC32 checksum. Before the monitor
 is relocated into RAM, as a result of a bad CRC you will be working
 with the compiled-in default environment - *silently*!!! [This is
 necessary, because the first environment variable we need is the
 "baudrate" setting for the console - if we have a bad CRC, we don't
 have any device yet where we could complain.]
 Note: once the monitor has been relocated, then it will complain if
 the default environment is used; a new CRC is computed as soon as you
 use the "saveenv" command to store a valid environment.
 - CFG_FAULT_ECHO_LINK_DOWN:
 		Echo the inverted Ethernet link state to the fault LED.
 		Note: If this option is active, then CFG_FAULT_MII_ADDR
 		      also needs to be defined.
 - CFG_FAULT_MII_ADDR:
 		MII address of the PHY to check for the Ethernet link state.
 - CFG_64BIT_VSPRINTF:
 		Makes vsprintf (and all *printf functions) support printing
 		of 64bit values by using the L quantifier
 - CFG_64BIT_STRTOUL:
 		Adds simple_strtoull that returns a 64bit value
 Low Level (hardware related) configuration options:
 ---------------------------------------------------
 - CFG_CACHELINE_SIZE:
 		Cache Line Size of the CPU.
 - CFG_DEFAULT_IMMR:
 		Default address of the IMMR after system reset.
 		Needed on some 8260 systems (MPC8260ADS, PQ2FADS-ZU,
 		and RPXsuper) to be able to adjust the position of
 		the IMMR register after a reset.
 - Floppy Disk Support:
 		CFG_FDC_DRIVE_NUMBER
 		the default drive number (default value 0)
 		CFG_ISA_IO_STRIDE
 		defines the spacing between fdc chipset registers
 		(default value 1)
 		CFG_ISA_IO_OFFSET
 		defines the offset of register from address. It
 		depends on which part of the data bus is connected to
 		the fdc chipset. (default value 0)
 		If CFG_ISA_IO_STRIDE CFG_ISA_IO_OFFSET and
 		CFG_FDC_DRIVE_NUMBER are undefined, they take their
 		default value.
 		if CFG_FDC_HW_INIT is defined, then the function
 		fdc_hw_init() is called at the beginning of the FDC
 		setup. fdc_hw_init() must be provided by the board
 		source code. It is used to make hardware dependant
 		initializations.
 - CFG_IMMR:	Physical address of the Internal Memory Mapped
 		Register; DO NOT CHANGE! (11-4)
 		[MPC8xx systems only]
 - CFG_INIT_RAM_ADDR:
 		Start address of memory area that can be used for
 		initial data and stack; please note that this must be
 		writable memory that is working WITHOUT special
 		initialization, i. e. you CANNOT use normal RAM which
 		will become available only after programming the
 		memory controller and running certain initialization
 		sequences.
 		U-Boot uses the following memory types:
 		- MPC8xx and MPC8260: IMMR (internal memory of the CPU)
 		- MPC824X: data cache
 		- PPC4xx:  data cache
 - CFG_GBL_DATA_OFFSET:
 		Offset of the initial data structure in the memory
 		area defined by CFG_INIT_RAM_ADDR. Usually
 		CFG_GBL_DATA_OFFSET is chosen such that the initial
 		data is located at the end of the available space
 		(sometimes written as (CFG_INIT_RAM_END -
 		CFG_INIT_DATA_SIZE), and the initial stack is just
 		below that area (growing from (CFG_INIT_RAM_ADDR +
 		CFG_GBL_DATA_OFFSET) downward.
 	Note:
 		On the MPC824X (or other systems that use the data
 		cache for initial memory) the address chosen for
 		CFG_INIT_RAM_ADDR is basically arbitrary - it must
 		point to an otherwise UNUSED address space between
 		the top of RAM and the start of the PCI space.

 		and crc32 is the correct crc32 which the
 		area should have.
 Building the Software:
 ======================
 Building U-Boot has been tested in native PPC environments (on a
 PowerBook G3 running LinuxPPC 2000) and in cross environments
 (running RedHat 6.x and 7.x Linux on x86, Solaris 2.6 on a SPARC, and
 NetBSD 1.5 on x86).
 If you are not using a native PPC environment, it is assumed that you
 have the GNU cross compiling tools available in your path and named
 with a prefix of "powerpc-linux-". If this is not the case, (e.g. if
 you are using Monta Vista's Hard Hat Linux CDK 1.2) you must change
 the definition of CROSS_COMPILE in Makefile. For HHL on a 4xx CPU,
 change it to:
 	CROSS_COMPILE = ppc_4xx-
 U-Boot is intended to be  simple  to  build.  After  installing	 the
 sources	 you must configure U-Boot for one specific board type. This
 is done by typing:
 	make NAME_config
 where "NAME_config" is the name of one of the existing
 configurations; the following names are supported:
 	ADCIOP_config		FPS860L_config		omap730p2_config
 	ADS860_config		GEN860T_config		pcu_e_config
 	AR405_config		GENIETV_config		PIP405_config
 	at91rm9200dk_config	GTH_config		QS823_config
 	CANBT_config		hermes_config		QS850_config
 	cmi_mpc5xx_config	hymod_config		QS860T_config
 	cogent_common_config	IP860_config		RPXlite_config
 	cogent_mpc8260_config	IVML24_config		RPXsuper_config
 	cogent_mpc8xx_config	IVMS8_config		rsdproto_config
 	CPCI405_config		JSE_config		Sandpoint8240_config
 	CPCIISER4_config	LANTEC_config		sbc8260_config
 	csb272_config		lwmon_config		SM850_config
 	CU824_config		MBX860T_config		SPD823TS_config
 	DUET_ADS_config		MBX_config		stxgp3_config
 	EBONY_config		MPC8260ADS_config	SXNI855T_config
 	ELPT860_config		MPC8540ADS_config	TQM823L_config
 	ESTEEM192E_config	MPC8560ADS_config	TQM850L_config
 	ETX094_config		NETVIA_config		TQM855L_config
 	FADS823_config		omap1510inn_config	TQM860L_config
 	FADS850SAR_config	omap1610h2_config	WALNUT405_config
 	FADS860T_config		omap1610inn_config	ZPC1900_config
 	FPS850L_config		omap5912osk_config
 Note: for some board special configuration names may exist; check if
       additional information is available from the board vendor; for
       instance, the TQM823L systems are available without (standard)
       or with LCD support. You can select such additional "features"
       when chosing the configuration, i. e.
       make TQM823L_config
 	- will configure for a plain TQM823L, i. e. no LCD support
       make TQM823L_LCD_config
 	- will configure for a TQM823L with U-Boot console on LCD
       etc.
 Finally, type "make all", and you should get some working U-Boot
 images ready for download to / installation on your system:
 - "u-boot.bin" is a raw binary image
 - "u-boot" is an image in ELF binary format
 - "u-boot.srec" is in Motorola S-Record format
 Please be aware that the Makefiles assume you are using GNU make, so
 for instance on NetBSD you might need to use "gmake" instead of
 native "make".
 If the system board that you have is not listed, then you will need
 to port U-Boot to your hardware platform. To do this, follow these
 steps:
 1.  Add a new configuration option for your board to the toplevel
     "Makefile" and to the "MAKEALL" script, using the existing
     entries as examples. Note that here and at many other places
     boards and other names are listed in alphabetical sort order. Please
     keep this order.
 2.  Create a new directory to hold your board specific code. Add any
     files you need. In your board directory, you will need at least
     the "Makefile", a "<board>.c", "flash.c" and "u-boot.lds".
 3.  Create a new configuration file "include/configs/<board>.h" for
     your board
 3.  If you're porting U-Boot to a new CPU, then also create a new
     directory to hold your CPU specific code. Add any files you need.
 4.  Run "make <board>_config" with your new name.
 5.  Type "make", and you should get a working "u-boot.srec" file
     to be installed on your target system.
 6.  Debug and solve any problems that might arise.
     [Of course, this last step is much harder than it sounds.]
 Testing of U-Boot Modifications, Ports to New Hardware, etc.:
 ==============================================================
 If you have modified U-Boot sources (for instance added a new	board
 or  support  for  new  devices,	 a new CPU, etc.) you are expected to
 provide feedback to the other developers. The feedback normally takes
 the form of a "patch", i. e. a context diff against a certain (latest
 official or latest in CVS) version of U-Boot sources.
 But before you submit such a patch, please verify that	your  modifi-
 cation	did not break existing code. At least make sure that *ALL* of
 the supported boards compile WITHOUT ANY compiler warnings. To do so,
 just run the "MAKEALL" script, which will configure and build U-Boot
 for ALL supported system. Be warned, this will take a while. You  can
 select	which  (cross)	compiler  to use by passing a `CROSS_COMPILE'
 environment variable to the script, i. e. to use the cross tools from
 MontaVista's Hard Hat Linux you can type
 	CROSS_COMPILE=ppc_8xx- MAKEALL
 or to build on a native PowerPC system you can type
 	CROSS_COMPILE=' ' MAKEALL

 Monitor Commands - Detailed Description:
 ========================================
 TODO.
 For now: just type "help <command>".
 Environment Variables:
 ======================
 U-Boot supports user configuration using Environment Variables which
 can be made persistent by saving to Flash memory.
 Environment Variables are set using "setenv", printed using
 "printenv", and saved to Flash using "saveenv". Using "setenv"
 without a value can be used to delete a variable from the
 environment. As long as you don't save the environment you are
 working with an in-memory copy. In case the Flash area containing the
 environment is erased by accident, a default environment is provided.
 Some configuration options can be set using Environment Variables:
   baudrate	- see CONFIG_BAUDRATE
   bootdelay	- see CONFIG_BOOTDELAY
   bootcmd	- see CONFIG_BOOTCOMMAND
   bootargs	- Boot arguments when booting an RTOS image
   bootfile	- Name of the image to load with TFTP
   autoload	- if set to "no" (any string beginning with 'n'),
 		  "bootp" will just load perform a lookup of the
 		  configuration from the BOOTP server, but not try to
 		  load any image using TFTP
   autostart	- if set to "yes", an image loaded using the "bootp",
 		  "rarpboot", "tftpboot" or "diskboot" commands will
 		  be automatically started (by internally calling
 		  "bootm")
 		  If set to "no", a standalone image passed to the
 		  "bootm" command will be copied to the load address
 		  (and eventually uncompressed), but NOT be started.
 		  This can be used to load and uncompress arbitrary
 		  data.
   i2cfast	- (PPC405GP|PPC405EP only)
 		  if set to 'y' configures Linux I2C driver for fast
 		  mode (400kHZ). This environment variable is used in
 		  initialization code. So, for changes to be effective
 		  it must be saved and board must be reset.
   initrd_high	- restrict positioning of initrd images:
 		  If this variable is not set, initrd images will be
 		  copied to the highest possible address in RAM; this
 		  is usually what you want since it allows for
 		  maximum initrd size. If for some reason you want to
 		  make sure that the initrd image is loaded below the
 		  CFG_BOOTMAPSZ limit, you can set this environment
 		  variable to a value of "no" or "off" or "0".
 		  Alternatively, you can set it to a maximum upper
 		  address to use (U-Boot will still check that it
 		  does not overwrite the U-Boot stack and data).
 		  For instance, when you have a system with 16 MB
 		  RAM, and want to reserve 4 MB from use by Linux,
 		  you can do this by adding "mem=12M" to the value of
 		  the "bootargs" variable. However, now you must make
 		  sure that the initrd image is placed in the first
 		  12 MB as well - this can be done with
 		  setenv initrd_high 00c00000
 		  If you set initrd_high to 0xFFFFFFFF, this is an
 		  indication to U-Boot that all addresses are legal
 		  for the Linux kernel, including addresses in flash
 		  memory. In this case U-Boot will NOT COPY the
 		  ramdisk at all. This may be useful to reduce the
 		  boot time on your system, but requires that this
 		  feature is supported by your Linux kernel.
   ipaddr	- IP address; needed for tftpboot command
   loadaddr	- Default load address for commands like "bootp",
 		  "rarpboot", "tftpboot", "loadb" or "diskboot"
   loads_echo	- see CONFIG_LOADS_ECHO
   serverip	- TFTP server IP address; needed for tftpboot command
   bootretry	- see CONFIG_BOOT_RETRY_TIME
   bootdelaykey	- see CONFIG_AUTOBOOT_DELAY_STR
   bootstopkey	- see CONFIG_AUTOBOOT_STOP_STR
   ethprime	- When CONFIG_NET_MULTI is enabled controls which
 		  interface is used first.
   ethact	- When CONFIG_NET_MULTI is enabled controls which
 		  interface is currently active. For example you
 		  can do the following
 		  => setenv ethact FEC ETHERNET
 		  => ping 192.168.0.1 # traffic sent on FEC ETHERNET
 		  => setenv ethact SCC ETHERNET
 		  => ping 10.0.0.1 # traffic sent on SCC ETHERNET
    netretry	- When set to "no" each network operation will
 		  either succeed or fail without retrying.
 		  When set to "once" the network operation will
 		  fail when all the available network interfaces
 		  are tried once without success.
 		  Useful on scripts which control the retry operation
 		  themselves.
    vlan		- When set to a value < 4095 the traffic over
 		  ethernet is encapsulated/received over 802.1q
 		  VLAN tagged frames.
 The following environment variables may be used and automatically
 updated by the network boot commands ("bootp" and "rarpboot"),
 depending the information provided by your boot server:
   bootfile	- see above
   dnsip		- IP address of your Domain Name Server
   dnsip2	- IP address of your secondary Domain Name Server
   gatewayip	- IP address of the Gateway (Router) to use
   hostname	- Target hostname
   ipaddr	- see above
   netmask	- Subnet Mask
   rootpath	- Pathname of the root filesystem on the NFS server
   serverip	- see above
 There are two special Environment Variables:
   serial#	- contains hardware identification information such
 		  as type string and/or serial number
   ethaddr	- Ethernet address
 These variables can be set only once (usually during manufacturing of
 the board). U-Boot refuses to delete or overwrite these variables
 once they have been set once.
 Further special Environment Variables:
   ver		- Contains the U-Boot version string as printed
 		  with the "version" command. This variable is
 		  readonly (see CONFIG_VERSION_VARIABLE).
 Please note that changes to some configuration parameters may take
 only effect after the next boot (yes, that's just like Windoze :-).
 Command Line Parsing:
 =====================
 There are two different command line parsers available with U-Boot:
 the old "simple" one, and the much more powerful "hush" shell:
 Old, simple command line parser:
 --------------------------------
 - supports environment variables (through setenv / saveenv commands)
 - several commands on one line, separated by ';'
 - variable substitution using "... $(name) ..." syntax
 - special characters ('$', ';') can be escaped by prefixing with '\',
   for example:
 	setenv bootcmd bootm \$(address)
 - You can also escape text by enclosing in single apostrophes, for example:
 	setenv addip 'setenv bootargs $bootargs ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname::off'
 Hush shell:
 -----------
 - similar to Bourne shell, with control structures like
   if...then...else...fi, for...do...done; while...do...done,
   until...do...done, ...
 - supports environment ("global") variables (through setenv / saveenv
   commands) and local shell variables (through standard shell syntax
   "name=value"); only environment variables can be used with "run"
   command
 General rules:
 --------------
 (1) If a command line (or an environment variable executed by a "run"
     command) contains several commands separated by semicolon, and
     one of these commands fails, then the remaining commands will be
     executed anyway.
 (2) If you execute several variables with one call to run (i. e.
     calling run with a list af variables as arguments), any failing
     command will cause "run" to terminate, i. e. the remaining
     variables are not executed.
 Note for Redundant Ethernet Interfaces:
 =======================================
 Some boards come with redundant ethernet interfaces; U-Boot supports
 such configurations and is capable of automatic selection of a
 "working" interface when needed. MAC assignment works as follows:
 Network interfaces are numbered eth0, eth1, eth2, ... Corresponding
 MAC addresses can be stored in the environment as "ethaddr" (=>eth0),
 "eth1addr" (=>eth1), "eth2addr", ...
 If the network interface stores some valid MAC address (for instance
 in SROM), this is used as default address if there is NO correspon-
 ding setting in the environment; if the corresponding environment
 variable is set, this overrides the settings in the card; that means:
 o If the SROM has a valid MAC address, and there is no address in the
   environment, the SROM's address is used.
 o If there is no valid address in the SROM, and a definition in the
   environment exists, then the value from the environment variable is
   used.
 o If both the SROM and the environment contain a MAC address, and
   both addresses are the same, this MAC address is used.
 o If both the SROM and the environment contain a MAC address, and the
   addresses differ, the value from the environment is used and a
   warning is printed.
 o If neither SROM nor the environment contain a MAC address, an error
   is raised.
 Image Formats:
 ==============
 The "boot" commands of this monitor operate on "image" files which
 can be basicly anything, preceeded by a special header; see the
 definitions in include/image.h for details; basicly, the header
 defines the following image properties:

 Linux Support:
 ==============
 Although U-Boot should support any OS or standalone application
 easily, the main focus has always been on Linux during the design of
 U-Boot.
 U-Boot includes many features that so far have been part of some
 special "boot loader" code within the Linux kernel. Also, any
 "initrd" images to be used are no longer part of one big Linux image;
 instead, kernel and "initrd" are separate images. This implementation
 serves several purposes:
 - the same features can be used for other OS or standalone
   applications (for instance: using compressed images to reduce the
   Flash memory footprint)
 - it becomes much easier to port new Linux kernel versions because
   lots of low-level, hardware dependent stuff are done by U-Boot
 - the same Linux kernel image can now be used with different "initrd"
   images; of course this also means that different kernel images can
   be run with the same "initrd". This makes testing easier (you don't
   have to build a new "zImage.initrd" Linux image when you just
   change a file in your "initrd"). Also, a field-upgrade of the
   software is easier now.
 Linux HOWTO:
 ============
 Porting Linux to U-Boot based systems:
 ---------------------------------------
 U-Boot cannot save you from doing all the necessary modifications to
 configure the Linux device drivers for use with your target hardware
 (no, we don't intend to provide a full virtual machine interface to
 Linux :-).
 But now you can ignore ALL boot loader code (in arch/ppc/mbxboot).
 Just make sure your machine specific header file (for instance
 include/asm-ppc/tqm8xx.h) includes the same definition of the Board
 Information structure as we define in include/u-boot.h, and make
 sure that your definition of IMAP_ADDR uses the same value as your
 U-Boot configuration in CFG_IMMR.
 Configuring the Linux kernel:
 -----------------------------
 No specific requirements for U-Boot. Make sure you have some root
 device (initial ramdisk, NFS) for your target system.
 Building a Linux Image:
 -----------------------
 With U-Boot, "normal" build targets like "zImage" or "bzImage" are
 not used. If you use recent kernel source, a new build target
 "uImage" will exist which automatically builds an image usable by
 U-Boot. Most older kernels also have support for a "pImage" target,
 which was introduced for our predecessor project PPCBoot and uses a
 100% compatible format.
 Example:
 	make TQM850L_config
 	make oldconfig
 	make dep
 	make uImage
 The "uImage" build target uses a special tool (in 'tools/mkimage') to
 encapsulate a compressed Linux kernel image with header	 information,
 CRC32 checksum etc. for use with U-Boot. This is what we are doing:
 * build a standard "vmlinux" kernel image (in ELF binary format):
 * convert the kernel into a raw binary image:
 	${CROSS_COMPILE}-objcopy -O binary \
 				 -R .note -R .comment \
 				 -S vmlinux linux.bin
 * compress the binary image:
 	gzip -9 linux.bin
 * package compressed binary image for U-Boot:
 	mkimage -A ppc -O linux -T kernel -C gzip \
 		-a 0 -e 0 -n "Linux Kernel Image" \
 		-d linux.bin.gz uImage
 The "mkimage" tool can also be used to create ramdisk images for use
 with U-Boot, either separated from the Linux kernel image, or
 combined into one file. "mkimage" encapsulates the images with a 64
 byte header containing information about target architecture,
 operating system, image type, compression method, entry points, time
 stamp, CRC32 checksums, etc.
 "mkimage" can be called in two ways: to verify existing images and
 print the header information, or to build new images.
 In the first form (with "-l" option) mkimage lists the information
 contained in the header of an existing U-Boot image; this includes
 checksum verification:
 	tools/mkimage -l image
 	  -l ==> list image header information
 The second form (with "-d" option) is used to build a U-Boot image
 from a "data file" which is used as image payload:
 	tools/mkimage -A arch -O os -T type -C comp -a addr -e ep \
 		      -n name -d data_file image
 	  -A ==> set architecture to 'arch'
 	  -O ==> set operating system to 'os'
 	  -T ==> set image type to 'type'
 	  -C ==> set compression type 'comp'
 	  -a ==> set load address to 'addr' (hex)
 	  -e ==> set entry point to 'ep' (hex)
 	  -n ==> set image name to 'name'
 	  -d ==> use image data from 'datafile'
 Right now, all Linux kernels for PowerPC systems use the same load
 address (0x00000000), but the entry point address depends on the
 kernel version:
 - 2.2.x kernels have the entry point at 0x0000000C,
 - 2.3.x and later kernels have the entry point at 0x00000000.
 So a typical call to build a U-Boot image would read:
 	-> tools/mkimage -n '2.4.4 kernel for TQM850L' \
 	> -A ppc -O linux -T kernel -C gzip -a 0 -e 0 \
 	> -d /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/ppc/coffboot/vmlinux.gz \
 	> examples/uImage.TQM850L
 	Image Name:   2.4.4 kernel for TQM850L
 	Created:      Wed Jul 19 02:34:59 2000
 	Image Type:   PowerPC Linux Kernel Image (gzip compressed)
 	Data Size:    335725 Bytes = 327.86 kB = 0.32 MB
 	Load Address: 0x00000000
 	Entry Point:  0x00000000
 To verify the contents of the image (or check for corruption):
 	-> tools/mkimage -l examples/uImage.TQM850L
 	Image Name:   2.4.4 kernel for TQM850L
 	Created:      Wed Jul 19 02:34:59 2000
 	Image Type:   PowerPC Linux Kernel Image (gzip compressed)
 	Data Size:    335725 Bytes = 327.86 kB = 0.32 MB
 	Load Address: 0x00000000
 	Entry Point:  0x00000000
 NOTE: for embedded systems where boot time is critical you can trade
 speed for memory and install an UNCOMPRESSED image instead: this
 needs more space in Flash, but boots much faster since it does not
 need to be uncompressed:
 	-> gunzip /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/ppc/coffboot/vmlinux.gz
 	-> tools/mkimage -n '2.4.4 kernel for TQM850L' \
 	> -A ppc -O linux -T kernel -C none -a 0 -e 0 \
 	> -d /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/ppc/coffboot/vmlinux \
 	> examples/uImage.TQM850L-uncompressed
 	Image Name:   2.4.4 kernel for TQM850L
 	Created:      Wed Jul 19 02:34:59 2000
 	Image Type:   PowerPC Linux Kernel Image (uncompressed)
 	Data Size:    792160 Bytes = 773.59 kB = 0.76 MB
 	Load Address: 0x00000000
 	Entry Point:  0x00000000
 Similar you can build U-Boot images from a 'ramdisk.image.gz' file
 when your kernel is intended to use an initial ramdisk:
 	-> tools/mkimage -n 'Simple Ramdisk Image' \
 	> -A ppc -O linux -T ramdisk -C gzip \
 	> -d /LinuxPPC/images/SIMPLE-ramdisk.image.gz examples/simple-initrd
 	Image Name:   Simple Ramdisk Image
 	Created:      Wed Jan 12 14:01:50 2000
 	Image Type:   PowerPC Linux RAMDisk Image (gzip compressed)
 	Data Size:    566530 Bytes = 553.25 kB = 0.54 MB
 	Load Address: 0x00000000
 	Entry Point:  0x00000000
 Installing a Linux Image:
 -------------------------
 To downloading a U-Boot image over the serial (console) interface,
 you must convert the image to S-Record format:
 	objcopy -I binary -O srec examples/image examples/image.srec
 The 'objcopy' does not understand the information in the U-Boot
 image header, so the resulting S-Record file will be relative to
 address 0x00000000. To load it to a given address, you need to
 specify the target address as 'offset' parameter with the 'loads'
 command.
 Example: install the image to address 0x40100000 (which on the
 TQM8xxL is in the first Flash bank):
 	=> erase 40100000 401FFFFF
 	.......... done
 	Erased 8 sectors
 	=> loads 40100000
 	## Ready for S-Record download ...
 	~>examples/image.srec
 	1 2 3 4 5 6 7 8 9 10 11 12 13 ...
 	...
 	15989 15990 15991 15992
 	[file transfer complete]
 	[connected]
 	## Start Addr = 0x00000000
 You can check the success of the download using the 'iminfo' command;
 this includes a checksum verification so you  can  be  sure  no	 data
 corruption happened:
 	=> imi 40100000
 	## Checking Image at 40100000 ...
 	   Image Name:	 2.2.13 for initrd on TQM850L
 	   Image Type:	 PowerPC Linux Kernel Image (gzip compressed)

 	   Verifying Checksum ... OK
 Boot Linux:
 -----------
 The "bootm" command is used to boot an application that is stored in
 memory (RAM or Flash). In case of a Linux kernel image, the contents
 of the "bootargs" environment variable is passed to the kernel as
 parameters. You can check and modify this variable using the
 "printenv" and "setenv" commands:
 	=> printenv bootargs
 	bootargs=root=/dev/ram
 	=> setenv bootargs root=/dev/nfs rw nfsroot=10.0.0.2:/LinuxPPC nfsaddrs=10.0.0.99:10.0.0.2
 	=> printenv bootargs
 	bootargs=root=/dev/nfs rw nfsroot=10.0.0.2:/LinuxPPC nfsaddrs=10.0.0.99:10.0.0.2
 	=> bootm 40020000

 More About U-Boot Image Types:
 ------------------------------
 U-Boot supports the following image types:
    "Standalone Programs" are directly runnable in the environment
 	provided by U-Boot; it is expected that (if they behave
 	well) you can continue to work in U-Boot after return from
 	the Standalone Program.
    "OS Kernel Images" are usually images of some Embedded OS which
 	will take over control completely. Usually these programs
 	will install their own set of exception handlers, device
 	drivers, set up the MMU, etc. - this means, that you cannot
 	expect to re-enter U-Boot except by resetting the CPU.
    "RAMDisk Images" are more or less just data blocks, and their
 	parameters (address, size) are passed to an OS kernel that is
 	being started.
    "Multi-File Images" contain several images, typically an OS
 	(Linux) kernel image and one or more data images like
 	RAMDisks. This construct is useful for instance when you want
 	to boot over the network using BOOTP etc., where the boot
 	server provides just a single image file, but you want to get
 	for instance an OS kernel and a RAMDisk image.
 	"Multi-File Images" start with a list of image sizes, each
 	image size (in bytes) specified by an "uint32_t" in network
 	byte order. This list is terminated by an "(uint32_t)0".
 	Immediately after the terminating 0 follow the images, one by
 	one, all aligned on "uint32_t" boundaries (size rounded up to
 	a multiple of 4 bytes).
    "Firmware Images" are binary images containing firmware (like
 	U-Boot or FPGA images) which usually will be programmed to
 	flash memory.
    "Script files" are command sequences that will be executed by
 	U-Boot's command interpreter; this feature is especially
 	useful when you configure U-Boot to use a real shell (hush)
 	as command interpreter.
 Standalone HOWTO:
 =================
 One of the features of U-Boot is that you can dynamically load and
 run "standalone" applications, which can use some resources of
 U-Boot like console I/O functions or interrupt services.
 Two simple examples are included with the sources:
 "Hello World" Demo:
 -------------------
 'examples/hello_world.c' contains a small "Hello World" Demo
 application; it is automatically compiled when you build U-Boot.
 It's configured to run at address 0x00040004, so you can play with it
 like that:
 	=> loads
 	## Ready for S-Record download ...
 	~>examples/hello_world.srec
 	1 2 3 4 5 6 7 8 9 10 11 ...
 	[file transfer complete]
 	[connected]
 	## Start Addr = 0x00040004
 	=> go 40004 Hello World! This is a test.
 	## Starting application at 0x00040004 ...
 	Hello World
 	argc = 7
 	argv[0] = "40004"
 	argv[1] = "Hello"
 	argv[2] = "World!"
 	argv[3] = "This"
 	argv[4] = "is"
 	argv[5] = "a"
 	argv[6] = "test."
 	argv[7] = "<NULL>"
 	Hit any key to exit ...
 	## Application terminated, rc = 0x0
 Another example, which demonstrates how to register a CPM interrupt
 handler with the U-Boot code, can be found in 'examples/timer.c'.
 Here, a CPM timer is set up to generate an interrupt every second.
 The interrupt service routine is trivial, just printing a '.'
 character, but this is just a demo program. The application can be
 controlled by the following keys:
 	? - print current values og the CPM Timer registers
 	b - enable interrupts and start timer
 	e - stop timer and disable interrupts
 	q - quit application
 	=> loads
 	## Ready for S-Record download ...
 	~>examples/timer.srec

 Minicom warning:
 ================
 Over time, many people have reported problems when trying to use the
 "minicom" terminal emulation program for serial download. I (wd)
 consider minicom to be broken, and recommend not to use it. Under
 Unix, I recommend to use C-Kermit for general purpose use (and
 especially for kermit binary protocol download ("loadb" command), and
 use "cu" for S-Record download ("loads" command).
 Nevertheless, if you absolutely want to use it try adding this
 configuration to your "File transfer protocols" section:
 	   Name	   Program			Name U/D FullScr IO-Red. Multi
 	X  kermit  /usr/bin/kermit -i -l %l -s	 Y    U	   Y	   N	  N
 	Y  kermit  /usr/bin/kermit -i -l %l -r	 N    D	   Y	   N	  N
 NetBSD Notes:
 =============
 Starting at version 0.9.2, U-Boot supports NetBSD both as host
 (build U-Boot) and target system (boots NetBSD/mpc8xx).
 Building requires a cross environment; it is known to work on
 NetBSD/i386 with the cross-powerpc-netbsd-1.3 package (you will also
 need gmake since the Makefiles are not compatible with BSD make).
 Note that the cross-powerpc package does not install include files;
 attempting to build U-Boot will fail because <machine/ansi.h> is
 missing.  This file has to be installed and patched manually:
 	# cd /usr/pkg/cross/powerpc-netbsd/include
 	# mkdir powerpc
 	# ln -s powerpc machine
 	# cp /usr/src/sys/arch/powerpc/include/ansi.h powerpc/ansi.h
 	# ${EDIT} powerpc/ansi.h	## must remove __va_list, _BSD_VA_LIST
 Native builds *don't* work due to incompatibilities between native
 and U-Boot include files.
 Booting assumes that (the first part of) the image booted is a
 stage-2 loader which in turn loads and then invokes the kernel
 proper. Loader sources will eventually appear in the NetBSD source
 tree (probably in sys/arc/mpc8xx/stand/u-boot_stage2/); in the
 meantime, send mail to bruno@exet-ag.de and/or wd@denx.de for
 details.
 Implementation Internals:
 =========================
 The following is not intended to be a complete description of every
 implementation detail. However, it should help to understand the
 inner workings of U-Boot and make it easier to port it to custom
 hardware.
 Initial Stack, Global Data:
 ---------------------------
 The implementation of U-Boot is complicated by the fact that U-Boot
 starts running out of ROM (flash memory), usually without access to
 system RAM (because the memory controller is not initialized yet).
 This means that we don't have writable Data or BSS segments, and BSS
 is not initialized as zero. To be able to get a C environment working
 at all, we have to allocate at least a minimal stack. Implementation
 options for this are defined and restricted by the CPU used: Some CPU
 models provide on-chip memory (like the IMMR area on MPC8xx and
 MPC826x processors), on others (parts of) the data cache can be
 locked as (mis-) used as memory, etc.
 	Chris Hallinan posted a good summary of	 these	issues	to  the
 	u-boot-users mailing list:
 	Subject: RE: [U-Boot-Users] RE: More On Memory Bank x (nothingness)?
 	From: "Chris Hallinan" <clh@net1plus.com>
 	Date: Mon, 10 Feb 2003 16:43:46 -0500 (22:43 MET)
 	...
 	Correct me if I'm wrong, folks, but the way I understand it
 	is this: Using DCACHE as initial RAM for Stack, etc, does not
 	require any physical RAM backing up the cache. The cleverness
 	is that the cache is being used as a temporary supply of
 	necessary storage before the SDRAM controller is setup. It's
 	beyond the scope of this list to expain the details, but you
 	can see how this works by studying the cache architecture and
 	operation in the architecture and processor-specific manuals.
 	OCM is On Chip Memory, which I believe the 405GP has 4K. It
 	is another option for the system designer to use as an
 	initial stack/ram area prior to SDRAM being available. Either
 	option should work for you. Using CS 4 should be fine if your
 	board designers haven't used it for something that would
 	cause you grief during the initial boot! It is frequently not
 	used.
 	CFG_INIT_RAM_ADDR should be somewhere that won't interfere
 	with your processor/board/system design. The default value
 	you will find in any recent u-boot distribution in
 	Walnut405.h should work for you. I'd set it to a value larger
 	than your SDRAM module. If you have a 64MB SDRAM module, set
 	it above 400_0000. Just make sure your board has no resources
 	that are supposed to respond to that address! That code in
 	start.S has been around a while and should work as is when
 	you get the config right.
 	-Chris Hallinan

 It is essential to remember this, since it has some impact on the C
 code for the initialization procedures:
 * Initialized global data (data segment) is read-only. Do not attempt
   to write it.
 * Do not use any unitialized global data (or implicitely initialized
   as zero data - BSS segment) at all - this is undefined, initiali-
   zation is performed later (when relocating to RAM).
 * Stack space is very limited. Avoid big data buffers or things like
   that.
 Having only the stack as writable memory limits means we cannot use
 normal global data to share information beween the code. But it
 turned out that the implementation of U-Boot can be greatly
 simplified by making a global data structure (gd_t) available to all
 functions. We could pass a pointer to this data as argument to _all_
 functions, but this would bloat the code. Instead we use a feature of
 the GCC compiler (Global Register Variables) to share the data: we
 place a pointer (gd) to the global data into a register which we
 reserve for this purpose.
 When choosing a register for such a purpose we are restricted by the
 relevant  (E)ABI  specifications for the current architecture, and by
 GCC's implementation.
 For PowerPC, the following registers have specific use:
 	R1:	stack pointer
 	R2:	TOC pointer
 	R3-R4:	parameter passing and return values
 	R5-R10: parameter passing
 	R13:	small data area pointer
 	R30:	GOT pointer
 	R31:	frame pointer
 	(U-Boot also uses R14 as internal GOT pointer.)
     ==> U-Boot will use R29 to hold a pointer to the global data
     Note: on PPC, we could use a static initializer (since the
     address of the global data structure is known at compile time),
     but it turned out that reserving a register results in somewhat
     smaller code - although the code savings are not that big (on
     average for all boards 752 bytes for the whole U-Boot image,
     624 text + 127 data).
 On ARM, the following registers are used:
 	R0:	function argument word/integer result
 	R1-R3:	function argument word
 	R9:	GOT pointer
 	R10:	stack limit (used only if stack checking if enabled)
 	R11:	argument (frame) pointer
 	R12:	temporary workspace
 	R13:	stack pointer
 	R14:	link register
 	R15:	program counter
     ==> U-Boot will use R8 to hold a pointer to the global data
 Memory Management:
 ------------------
 U-Boot runs in system state and uses physical addresses, i.e. the
 MMU is not used either for address mapping nor for memory protection.
 The available memory is mapped to fixed addresses using the memory
 controller. In this process, a contiguous block is formed for each
 memory type (Flash, SDRAM, SRAM), even when it consists of several
 physical memory banks.
 U-Boot is installed in the first 128 kB of the first Flash bank (on
 TQM8xxL modules this is the range 0x40000000 ... 0x4001FFFF). After
 booting and sizing and initializing DRAM, the code relocates itself
 to the upper end of DRAM. Immediately below the U-Boot code some
 memory is reserved for use by malloc() [see CFG_MALLOC_LEN
 configuration setting]. Below that, a structure with global Board
 Info data is placed, followed by the stack (growing downward).
 Additionally, some exception handler code is copied to the low 8 kB
 of DRAM (0x00000000 ... 0x00001FFF).
 So a typical memory configuration with 16 MB of DRAM could look like
 this:
 	0x0000 0000	Exception Vector code
 	      :
 	0x0000 1FFF
 	0x0000 2000	Free for Application Use
 	      :
 	      :
 	      :
 	      :
 	0x00FB FF20	Monitor Stack (Growing downward)
 	0x00FB FFAC	Board Info Data and permanent copy of global data
 	0x00FC 0000	Malloc Arena
 	      :
 	0x00FD FFFF
 	0x00FE 0000	RAM Copy of Monitor Code
 	...		eventually: LCD or video framebuffer
 	...		eventually: pRAM (Protected RAM - unchanged by reset)
 	0x00FF FFFF	[End of RAM]
 System Initialization:
 ----------------------
 In the reset configuration, U-Boot starts at the reset entry point
 (on most PowerPC systens at address 0x00000100). Because of the reset
 configuration for CS0# this is a mirror of the onboard Flash memory.
 To be able to re-map memory U-Boot then jumps to its link address.
 To be able to implement the initialization code in C, a (small!)
 initial stack is set up in the internal Dual Ported RAM (in case CPUs
 which provide such a feature like MPC8xx or MPC8260), or in a locked
 part of the data cache. After that, U-Boot initializes the CPU core,
 the caches and the SIU.
 Next, all (potentially) available memory banks are mapped using a
 preliminary mapping. For example, we put them on 512 MB boundaries
 (multiples of 0x20000000: SDRAM on 0x00000000 and 0x20000000, Flash
 on 0x40000000 and 0x60000000, SRAM on 0x80000000). Then UPM A is
 programmed for SDRAM access. Using the temporary configuration, a
 simple memory test is run that determines the size of the SDRAM
 banks.
 When there is more than one SDRAM bank, and the banks are of
 different size, the largest is mapped first. For equal size, the first
 bank (CS2#) is mapped first. The first mapping is always for address
 0x00000000, with any additional banks following immediately to create
 contiguous memory starting from 0.
 Then, the monitor installs itself at the upper end of the SDRAM area
 and allocates memory for use by malloc() and for the global Board
 Info data; also, the exception vector code is copied to the low RAM
 pages, and the final stack is set up.
 Only after this relocation will you have a "normal" C environment;
 until that you are restricted in several ways, mostly because you are
 running from ROM, and because the code will have to be relocated to a
 new address in RAM.

 Coding Standards:
 -----------------
 All contributions to U-Boot should conform to the Linux kernel
 coding style; see the file "Documentation/CodingStyle" in your Linux
 kernel source directory.
 Please note that U-Boot is implemented in C (and to some small parts
 in Assembler); no C++ is used, so please do not use C++ style
 comments (//) in your code.
 Please also stick to the following formatting rules:
 - remove any trailing white space
 - use TAB characters for indentation, not spaces
 - make sure NOT to use DOS '\r\n' line feeds
 - do not add more than 2 empty lines to source files
 - do not add trailing empty lines to source files
 Submissions which do not conform to the standards may be returned
 with a request to reformat the changes.
 Submitting Patches:
 -------------------
 Since the number of patches for U-Boot is growing, we need to
 establish some rules. Submissions which do not conform to these rules
 may be rejected, even when they contain important and valuable stuff.
 When you send a patch, please include the following information with
 it:
 * For bug fixes: a description of the bug and how your patch fixes
   this bug. Please try to include a way of demonstrating that the
   patch actually fixes something.
 * For new features: a description of the feature and your
   implementation.
 * A CHANGELOG entry as plaintext (separate from the patch)
 * For major contributions, your entry to the CREDITS file
 * When you add support for a new board, don't forget to add this
   board to the MAKEALL script, too.
 * If your patch adds new configuration options, don't forget to
   document these in the README file.
 * The patch itself. If you are accessing the CVS repository use "cvs
   update; cvs diff -puRN"; else, use "diff -purN OLD NEW". If your
   version of diff does not support these options, then get the latest
   version of GNU diff.
   The current directory when running this command shall be the top
   level directory of the U-Boot source tree, or it's parent directory
   (i. e. please make sure that your patch includes sufficient
   directory information for the affected files).
   We accept patches as plain text, MIME attachments or as uuencoded
   gzipped text.
 * If one logical set of modifications affects or creates several
   files, all these changes shall be submitted in a SINGLE patch file.
 * Changesets that contain different, unrelated modifications shall be
   submitted as SEPARATE patches, one patch per changeset.
 Notes:
 * Before sending the patch, run the MAKEALL script on your patched
   source tree and make sure that no errors or warnings are reported
   for any of the boards.
 * Keep your modifications to the necessary minimum: A patch
   containing several unrelated changes or arbitrary reformats will be
   returned with a request to re-formatting / split it.
 * If you modify existing code, make sure that your new code does not
   add to the memory footprint of the code ;-) Small is beautiful!
   When adding new features, these should compile conditionally only
   (using #ifdef), and the resulting code with the new feature
   disabled must not need more memory than the old code without your
   modification.
