   Patch by Stefan Roese, 07 Sep 2006
 * Fix mkimage -l bug with multifile images on 64bit platforms
   Patch by David Updegraff, 06 Sep 2006
 * Fix build problems on sorcery board.
 * Fix coldfire build problems.
   Patch by Marian Balakowicz, 01 Sep 2006
 * Add support for a saving build objects in a separate directory.
   Modifications are based on the Linux kernel approach and support
   two use cases:
   1) Add O= to the make command line 'make O=/tmp/build all'
   2) Set environement variable BUILD_DIR to point to the desired location
 	'export BUILD_DIR=/tmp/build'
 	'make'
   The second approach can also be used with a MAKEALL script
 	'export BUILD_DIR=/tmp/build'
 	'./MAKEALL'
   Command line 'O=' setting overrides the BUILD_DIR environent variable.
   When none of the above methods is used the local build is performed
   and the object files are placed in the source directory.
 * Remove the board/netstar/crcit binary from git repository.
 * Fix tools/updater build error.
 * Fix tools/easylogo build error.
 * Fixed problems on PRS200 board caused by adding splash screen on MCC200

   Also added Linux like BUG() macros.
 * Coding Style cleanup.
   Patch by Stefano Babic, 31 Aug 2006
 * Add splashscreen support for MCC200 board.
 * Make the serial driver framework work with CONFIG_SERIAL_MULTI
   enabled
 * PCIe endpoint support for AMCC Yucca 440SPe board
   Patch by Tirumala R Marri, 26 Aug 2006
 * Improve DIMM detection for AMCC Yucca 440SPe board
   Improved the memory DIMM detection for the Yucca 440SPe board for
   the case where a memory DIMM is falsely detected as present.
   This issue is seen on some AMCC Yucca 440SPe validation boards if
   only one 512MB memory DIMM is installed, i.e. DIMM slot 0 is
   populated and DIMM slot 1 is empty.  In this case, U-Boot does
   not correctly detect that there is only one DIMM memory module
   installed and will falsely detect two DIMM memory modules are
   present and therefore U-Boot will not calculate the correct amount
   of total memory and u-boot will not booting up.

   Patch by Matej Kupljen, 10 Aug 2005
 * Check argument count in "mii" command.
   Problem pointed out by Andrew Dyer, 13 Jun 2005
 * Cleanup TQM5200 board configurations:
   - make highboot configurations use environment at high end, too,
     to avoid flash fragmentation
   - always use redundand environment
   - don't enable video code for modules without graphics controller
   - provide useful (though different) mtdparts settings
   - get rid of CONFIG_CS_AUTOCONF which was always set anyway
 * Extend mkconfig tool to print more useful target name
 * Add support for high-boot on TQM5200 and TQM5200S boards.
   Hint: the CPLD on the TQM5200 must be programmed with a software
   version supporting the high boot option! The new TQM5200S is
   already supporting this option. On the TQM5200 this option will be
   supported in configurations with MPC5200 rev B processors.
   To actually "high boot", set jumper X30 on the STK52xx.
   Patch by Martin Krause, 12 Jul 2006
 * Add support for new TQM5200 revisions
   - Support for TQM5200S (short version without graphic controller)
   - Support for modules with 'N' type S29GL128N Spansion flashes
     (requires changes to flash layout)
   - Support for MPC5200B cpu (mostly support for second SDRAM bank)
   Patch by Martin Krause, 07 Jul 2006
 * Fix support for PS/2 keyboard on TQM85xx boards
   The PS/2 keyobard driver for the TQM85xx modules only supports the
   internal DUART of the MPC85xx CPU. Since the MPC8560 doesn't
   include a DUART, the TQM8560 modules can't be used with the PS/2
   keyboard controller on the STK85xx board.
   The PS/2 keyboard driver should work with the modules TQM8540,
   TQM8541 and TQM8555, but it only has been tested on a TQM8540, yet.
   Make sure the PS/2 controller on the STK85xx is programmed. Jumper
   settings: X66 1-2, 9-10; X61 2-3
   Patch by Martin Krause, 21 Jun 2006
 * Adjust RTC century handling on STK52xx board to match Linux driver.
   Patch by Martin Krause, 12 Jun 2006
 * Adjust filenames for USB update images on TRAB board.
   During an automatic update via USB stick, U-Boot searches for
   images with the name "firmware.img" and "kernel.img". This names
   are now changed to "firmw_01.img" and "kernl_01.img". This is done,
   to prevent updates of new boards (with the new macronics "c" step
   flashes) with old, incompatible firmware or kernel versions.
   Patch by Martin Krause, 21 Jun 2006
 * Bugfix in VFD routine on TRAB board.
   Make sure upper lext pixel can be set to blue, too
   (so far only red was possible).
   Patch by Martin Krause, 15 Feb 2006
 * Enable buffered flash writes for TB5200 board.
 * Fix some bugs in TRAB board flash driver.
   - increase CFG_FLASH_ERASE_TOUT from 2 to 15 seconds
   - use CFG_FLASH_WRITE_TOUT for programming instead of CFG_FLASH_ERASE_TOUT
   - remove "Unlock Bypass" mode, because macronix flashes do not support
     this mode officially
   - fix flash reset command from 0x00FF to 0x00F0. 0x00FF is only specified
     for Intel compatible flashes, not for AMD compatible.
   Patch by Martin Krause, 15 Feb 2006
 * Add additional error messages to flash driver on TRAB board
   (for erase errors and timeout errors)
   Patch by Martin Krause, 14 Feb 2006
 * Add support for TB5200 board
   The TB5200 ("Tinybox") is a small baseboard for the TQM5200 module
   integrated in a little aluminium case.
   Patch by Martin Krause, 8 Jun 2006
 * Enable buffered flash writes for TQM5200 board.
 * Fix problems with SanDisk Corporation Cruzer Micro USB memory stick.
 * Add support for TQM885D board.
   Patch by Martin Krause, 20 Mar 2006
 * Fix FEC initialisation: All MII configuration is done via FEC1
   registers, but MII_SPEED was configured according to FEC used. So
   if only FEC2 was used, this caused the real MII_SPEED register in
   FEC1 to stay uninitalised, leqading to "mii_send STUCK!" messages.
   Fix: always configure MII_SPEED on FEC1 only.
   Patch by Markus Klotzbuecher, 12 Jul 2006
 * Add support for SPC1920 board.
   Patch by Markus Klotzbuecher, 12 Jul 2006
 * MCC200 board: support console on any one of the Quad UART ports.
 * Fix error in flash protection calculation on MCC200 board.
 * Major PCMCIA Cleanup to make code better readable and maintainable.
   Notes:
   - Board-dependend code for RPXLITE and RPXCLASSIC-based boards
     placed to the drivers/rpx_pmcia.c file to avoid duplication.
     Same for TQM8xx-based boards (drivers/tqm8xx_pmcia.c).
   - drivers/i82365.c has been split into two parts located at
     board/atc/ti113x.c and board/cpc45/pd67290.c (ATC and CPC45 are
     the only boards using CONFIG_82365).
   - Changes were tested for clean build and *very* *few* boards.
 * Fix timer problems on AMCC yucca board.
   Set Timer Clock Select to use CPU clock as a timer input source.
 * Bring yucca config more in line with other AMCC boards.
 * Add AMCC bamboo board to MAKEALL build script.

   reasonable TEXT_BASE, update default environment and enable keyed
   autoboot.
   Patch by Ladislav Michl, 16. Aug 2005
 * Add forgotten changes for the PLEB 2 Board.
   Patch by David Snowdon, 13. Aug 2005
 * Add support for wrPPMC7xx/74xx boards
   Patch by Richard Danter, 12 Aug 2005
 * Add support for gth2 board
   Patch by Thomas Lange, Aug 11 2005
 * Add support for CONFIG_SERIAL_MULTI on MPC5xxx
   Patch by Martin Krause, 8 Jun 2006
   This patch supports two serial consoles on boards with
   a MPC5xxx CPU. The console can be switched at runtime
   by setting stdin, stdout and stderr to the desired serial
   interface (serial0 or serial1). The PSCs to be used as
   console port are definded by CONFIG_PSC_CONSOLE
   and CONFIG_PSC_CONSOLE2.
   See README.serial_multi for details.
 * Bugfix in I2C initialisation on S3C2400.
   If the bus is blocked because of a previously interrupted
   transfer, up to eleven clocks are generated on the I2CSCL
   line to complete the transfer and to free the bus.
   With this fix pin I2CSCL (PG6) is really configured as GPIO
   so the clock pulses are really generated.
   Patch by Martin Krause, 04 Apr 2006
 * Fix DDR6 errata on TQM834x boards
   Patch by Thomas Waehner, 07 Mar 2006
 * Remove obsolete flash driver board/tqm5200/flash.c

 * Add support for PS/2 keyboard on TQM85xx board
   Patch by Martin Krause, 07 Nov 2005
   Tested on a STK85XX baseboard. Make sure the PS/2 controller
   has been programmed. Jumper Settings: X66 1-2, 9-10; X61 2-3
 * Fix TRAB channel switching delay for trab_fkt.bin standalone applikation
   In tsc2000_read_channel() the delay after setting the multiplexer
   to a temperature channel is increased from 1,5 ms to 10 ms. This
   is to allow the multiplexer inputs to stabilize after huge steps
   of the input signal level.
   Patch by Martin Krause, 08 Nov 2005
 * Adjust TQM5200 make targets
   Make the automatic CS configuration the default.
   The dedicated configurations CONFIG_TQM5200_AA, CONFIG_TQM5200_AB
   and CONFIG_TQM5200_AC are removed.
   "TQM5200_config" is now the default for STK52XX.200 base boards.
   On a STK52XX.100 base board "TQM5200_STK100_config" must be used.
   Patch by Martin Krause, 07 Nov 2005
 * Fix setting of environment variable "ver" on trab board
   The environment variable "ver" is now set before
   do_auto_update() is called, so that "ver" can be used
   in USB update scripts.
   Patch by Martin Krause, 27 Oct 2005

 * Nios II - Add Altera EP1C20, EP1S10 and EP1S40 boards
   Patch by Scott McNutt, 08 Jun 2006
 * Nios II - Add EPCS Controller bootrom work-around
   -When booting from an epcs controller, the epcs bootrom may leave the
   slave select in an asserted state causing soft reset hang. This
   patch ensures slave select is negated at reset.
   Patch by Scott McNutt, 08 Jun 2006

 * Fix Quad UART mapping on MCC200 board due to new HW revision
 * Fix JFFS2 support for legacy NAND driver.
 * Remove dependencies between DoC code and old legacy NAND driver.
 * Fix PM828_PCI target, for which PCI was *not* configured in.
 * Fix Lite5200B support: initialize SDelay register
   See Freescale's AN3221 "MPC5200B SDRAM Initialization and
   Configuration", 3.3.1 SDelay--MBAR + 0x0190
 * Changes/fixes for drivers/cfi_flash.c:
   - Add Intel legacy lock/unlock support to common CFI driver
     On some Intel flash's (e.g. Intel J3) legacy unlocking is
     supported, meaning that unlocking of one sector will unlock
     all sectors of this bank. Using this feature, unlocking
     of all sectors upon startup (via env var "unlock=yes") will
     get much faster.
   - Fixed problem with multiple reads of envronment variable
     "unlock" as pointed out by Reinhard Arlt & Anders Larsen.
   - Removed unwanted linefeeds from "protect" command when
     CFG_FLASH_PROTECTION is enabled.
   - Changed p3p400 board to use CFG_FLASH_PROTECTION
   Patch by Stefan Roese, 01 Apr 2006
 * Changes/fixes for drivers/cfi_flash.c:
   - Correctly handle the cases where CFG_HZ != 1000 (several
     XScale-based boards)
   - Fix the timeout calculation of buffered writes (off by a
     factor of 1000)
   Patch by Anders Larsen, 31 Mar 2006
 * Updates to common PPC4xx onboard (DDR)SDRAM init code (405 and 440)
   405 SDRAM: - The SDRAM parameters can now be defined in the board
 	       config file and the 405 SDRAM controller values will
 	       be calculated upon bootup (see PPChameleonEVB).
 	       When those settings are not defined in the board
 	       config file, the register setup will be as it is now,
 	       so this implementation should not break any current
 	       design using this code.
 	       Thanks to Andrea Marson from DAVE for this patch.
   440 DDR:   - Added function sdram_tr1_set to auto calculate the
 	       TR1 value for the DDR.
 	     - Added ECC support (see p3p440).

 * Change max size of uncompressed uImage's to 8MByte and add
   CFG_BOOTM_LEN to adjust this setting.
   As mentioned by Robin Getz on 2005-05-24 the size of uncompressed
   uImages was restricted to 4MBytes. This default size is now
   increased to 8Mbytes and can be overrided by setting CFG_BOOTM_LEN

   If a host controller sets up a region as prefetchable and
   a device's BAR denotes it as prefetchable, allocate the
   BAR into the prefetch region.
   If a BAR is prefetchable and no prefetchable region has

 * Word alignment fixes for word aligned NS16550 UART
   Patch by Jean-Paul Saman, 01 Mar 2005
   Fixes bug with UART that only supports word aligned access: removed
   "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" some
   (broken!) versions of GCC generate byte accesses when encountering
   the packed attribute regardless if the struct is already correctly
   aligned for a platform. Peripherals that can only handle word
   aligned access won't work properly when accessed with byte access.
   The struct NS16550 is already word aligned for REG_SIZE = 4, so
   there is no need to packed the struct in that case.

   (locked/unlocked).
   Only the U-Boot image and it's environment is protected,
   all other sectors are unprotected (unlocked) if flash
   hardware protection is used (CFG_FLASH_PROTECTION) and
   the environment variable "unlock" is set to "yes".

   Patch by Alex Bastos and Thomas Schaefer, 2005-08-29
 * Changes/fixes for drivers/cfi_flash.c:
   We *should* check if there are any error bits if the previous call
   returned ERR_OK (Otherwise we will have output an error message in
   flash_status_check() already.)  The original code would only check for
   error bits if flash_status_check() returns ERR_TIMEOUT.
   Patch by Marcus Hall, 23 Aug 2005
 * Changes/fixes for drivers/cfi_flash.c:
   - Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c

   of all unreleased (untagged) U-Boot images will be automatically
   extended upon compiletime with a part of the GIT commit ID and
   possibly with "dirty" if uncommited changes are detected.
   Here an example for the resulting version:
   "U-Boot 1.1.4-g3457ac18-dirty"
   The version is now maintained in the toplevel Makefile and the
   version headers are autogenerated.

 ======================================================================
 * Changes to Yellowstone & Yosemite 440EP/GR eval boards:
   - Changed GPIO setup to enable another address line in order to
     address 64M of FLASH.
   - Added function sdram_tr1_set to auto calculate the tr1 value for
     the DDR.
   Patch by Steven Blakeslee, 12 Dec 2005
 * MPC5200:  Set PCI retry counter to 0 = infinite retry;
   The default of 255 is too short for slow devices.
   Patch by Martin Nykodym, 12 Dec 2005
 * Change port configuration for O2DNT (CODEC1 on PSC1).
 * Fix register for PCI async mode on PPC440EP
   Patch by Youngchul Bang, 08 Dec 2005
 * Fix U-Boot linking problems (add .eh_frame segment to linker script)
   This segment may be required by some libgcc.a functions
   (like _udivdi3).
 * Fix DPRAM offset/size for MPC8541/8555.
   Simplify TQM85xx Makefile handling.
 * Fix data overflow (typo?) in rtc/ds1302.c
 * Fix U-Boot compilation for MIPS boards using ELDK 4.0
 * Add support for TQM8541/8555 boards, TQM85xx support reworked:
   - Support for TQM8541/8555 boards added.
   - Complete rework of TQM8540/8560 support.
   - Common TQM85xx code now supports all current TQM85xx platforms
     (TQM8540/8541/8555/8560).
   - DDR SDRAM size detection added.
   - CAS latency default values can be overwritten by setting "serial#"
     to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used.
     If problems are detected with this non default CAS latency,
     the default values will be used instead.
   - Flash size detection added.
   - Moved FCC ethernet driver initialization behind TSEC driver init
     -> TSEC is first device.
   Patch by Stefan Roese, 30 Nov 2005
 * Add support for AMCC 440SP, add support for AMCC Luan 440SP eval board.
   Patch by John Otken, 23 Nov 2005
 * Changed PPC44x startup message (cpu info, speed...) to common style:
   On PPC44x platforms, the startup message generated in "cpu.c" only
   comprised the ppc type and revision but not additional information
   like speed etc. Those speed infos where printed in the board specific
   code. This new implementation now prints all CPU infos in the common
   cpu specific code. No board specific code is needed anymore and
   therefore removed from all current 44x implementations.
   Patch by Stefan Roese, 27 Nov 2005
 * Adjust TQM834x PHY addresses for latest hardware revision.
 * Increase malloc arena on TQM5200 board to 256 kB.
   With 64 kb uniform flash sector size the old value of 128 kB was
   too small.
 * Fix miiphy global data initialization (problem on 4xx boards when
   no ethaddr is assigned). Initialization moved from
   miiphy_register() to eth_initialize().
   Based on initial patch for 4xx platform by Matthias Fuchs.
 * Remove unnnecessary #include <linux/types.h> from include/asm-*/u-boot.h
 * Allow use of include/image.h and include/asm-*/u-boot.h in proprietary code.
   The COPYING file was extended to make clear that these files can be
   used in non-GPL code, too.
   Also, a corresponding note was placed in the headers of the affected files.
 * Add support for Prodrive P3P440 board:
   - Added onboard PPC440 DDR autodetection in cpu/ppc/sdram.c
   - CFG_FLASH_QUIET_TEST added to use the common CFI driver
     for bank autodetection
   Patch by Stefan Roese, 22 Nov 2005
 * Change all '$(...)' variable references into '${...}'
   which makes the environment compatible with the hush shell.
   WARNING: Support for the old '$(...)' syntax will be
   discontinued in a later version.
 * Minor changes to init flags in TQM834x PCI.
 * Fix Bamboo DDR SDRAM initialization (problem with onboard SDRAM)
   Patch by Stefan Roese, 15 Nov 2005

   Patch by Stefan Roese, 01 Nov 2005
 * Fix external IRQ configuration on Yellowstone & Yosemite
   Patch by Stefan Roese, 28 Oct 2005
 * Add support for multiple PHYs.
   Tested on the following boards:
 	cmcpu2	    (at91rm9200/ether.c)
 	PPChameleon (ppc4xx/4xx_enet.c)
 	yukon	    (mpc8220/fec.c)
 	uc100	    (mpc8xx/fec.c)
 	tqm834x	    (mpc834x/tsec.c) with EEPRO100
 	lite5200    (mpc5xxx/fec.c) with EEPRO100 card (drivers/eepro100.c)
   Main changes include:
   common/miiphyutil.c
   - miiphy_register routine was added to allow multiple PHYs to be registered
   - miiphy_read and miiphy_write are now defined in this file, and
     require additional argument (char *devname)
   - other miiphy_* routines also require additional device name argument
   ../lib_i386/board.c
   ../lib_ppc/board.c
   Calling reset_phy() was moved to be executed *after* eth_initialize().
   This is necessary as now some of the implementations of reset_phy()
   may need to use miiphy_reset() which is not allowed before eth_initialize()
   as eth_initialize registers all required miiphy_* routines.
   Tested on IP860 and PHY initializes properly after this change.

 * Eliminate hard-coded address of Ethernet transfer buffer on at91rm9200
   Patch by Anders Larsen, 07 Oct 2005
   The Atmel errata #11 states that the transfer buffer descriptor
   table must be aligned on a 16-word boundary. As it turned out, this
   is insufficient - it seems the table must be aligned on a boundary
   at least as large as the table itself (in Linux this is not an
   issue - the table is aligned on a PAGE_SIZE (4096) boundary).
 * Fixed compilation for ARM when using a (standard) hard-FP toolchain
   Patch by Anders Larsen, 07 Oct 2005

 * Fix warnings for PCI code on ixp
   Patch by Joe <lgxue@yahoo.com>, 13 Jan 2005
 * virtex2 fix for bogus download error messages
   The virtex2 FPGA download code watches for init going active during
   a download of config data as an error condition. init also goes
   active after a configuration is finished in concert with the done
   signal. So far, the code does not check for done active until all
   of the configuration data is sent. If configuration data has a few
   extra pad bytes at the end, this would cause an error message even
   though the download had suceeded.
   NOTE: virtex2 slave serial and spartan2 versions may still have the
   same problem.
   Patch by Andrew Dyer, 12 Jan 2005

   Patch by Stefan Roese, 08 Aug 2005
 * Fix compiler warnings with older GCC versions
 * Add common (with Linux) MTD partition scheme and "mtdparts" command
   Old, obsolete and duplicated code was cleaned up and replace by the
   new partitioning method. There are two possible approaches now:
   The first one is to define a single, static partition:
   #undef CONFIG_JFFS2_CMDLINE
   #define CONFIG_JFFS2_DEV		 "nor0"
   #define CONFIG_JFFS2_PART_SIZE	 0xFFFFFFFF	/* use whole device */
   #define CONFIG_JFFS2_PART_SIZE	 0x00100000	/* use 1MB */
   #define CONFIG_JFFS2_PART_OFFSET	 0x00000000
   The second method uses the mtdparts command line option and dynamic
   partitioning:
   /* mtdparts command line support */
   #define CONFIG_JFFS2_CMDLINE
   #define MTDIDS_DEFAULT	 "nor1=zuma-1,nor2=zuma-2"
   #define MTDPARTS_DEFAULT	 "mtdparts=zuma-1:-(jffs2),zuma-2:-(user)"
   Command line of course produces bigger images, and may be inappropriate
   for some targets, so by default it's off.

   LBA48 fixes
 * 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)

        allocation of DPRAM
     2. shut down FEC after network transfers

 * 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:

     "common/main.c" can use the "reset_cmd_timeout()" function before
     entering the main loop
   - add DTT support for adm1021 (new file dtt/adm1021.c; config
     slightly different. see include/configs/hymod.h for an example

     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

 * Add support for V37 board
   (patch by Jón Benediktsson, 11 Dec 2002)
 * Update baudrate in bd_info when it gets changed
 * Add watchdog trigger points while waiting for serial port
   (so far only 8xx -- needed on LWMON with 100ms watchdog)
 * Improve command line tool to access the U-Boot's environment
   (figuration of the utility, using a config file)
 * Add single quote support for (old) command line parser
 * Switch LWMON board default config from FRAM to EEPROM;
   in POST, EEPROM shows up on 8 addresses
 ======================================================================
 Changes for U-Boot 0.2.0:
 ======================================================================
 * Use 1-byte-read instead of -write for iprobe() function
   Add i2c commands to PM826 config
 * extend I2C POST code: check for list on known addresses
 * Improve log buffer code; use "loglevel" to decide which messages
   to log on the console, too (like in Linux); get rid of "logstart"
 * Add command line tool to access the U-Boot's environment
   (board-specific for TRAB now, to be fixed later)

   Increase number of network RX buffers (PKTBUFSRX in
   "include/net.h") for EEPRO100 based boards (especially SP8240)
   which showed "Receiver is not ready" errors when U-Boot was
   processing the receive buffers slower than the network controller
   was filling them.
 * Patch by Andreas Oberritter, 09 Nov 2002:
   Change behaviour of NetLoop(): return -1 for errors, filesize
   otherwise; return code 0 is valid an means no file loaded - in this
   case the environment still gets updated!
