With this change driver will benefit from existing phylib and thus
custom phy functionality implemented in the driver will go away:
* Instantiation of the driver is now much shorter - 2 parameters
instead of 4.
* Simplified phy management/functoinality in driver is replaced with
rich functionality of phylib.
* Support of custom phy initialization is now done with existing
"board_phy_config".Note that after this change some previously used config options
(driver-specific PHY configuration) will be obsolete and they are simply
substituted with similar options of phylib.For example:
* CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled
by default.
* CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy
explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise
automatically the first discovered on MDIO bus phy will be usedI believe there's no need now in "doc/README.designware_eth" because
user only needs to instantiate the driver with "designware_initialize"
whose prototype exists in "include/netdev.h".Cc: Joe Hershberger

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.Replace FALSE, False with false. Replace TRUE, True with true.

This patch adds support for the X600 SPEAr600 based board. Its also
the first SPEAr600 board that uses the newly introduced SPEAr600
SPL support. Xloader is not necessary any more. By using the new
"u-boot.spr" make target, one image will generated containing both,
U-Boot SPL (with mkimage header as needed by the SPEAr BootROM, and
the main U-Boot with mkimage header.Signed-off-by: Stefan Roese

Enable data cache with 1:1 mapping of DDR to enable fast file
transfer over tty which was doing lot of copy.This feature is enabled only for flashing operation i.e. when
CONFIG_SPEAR_USBTTY is enabled.This has been tested on SPEAr320, SPEAr600 and SPEAr900 evaluation
boards.Following figures show an estimate on the performance improvements. The
test setup was a Linux host (not Windows) and involved measurement of
only binary transfer time, through kermit. The flash erase and flash
copy time would be unaffected by these patches.Another thing is this that the timings remained more or less same across
ARM9 and Cortex based devices, hence reporting only one of the cases.Before Enhancements

This patch adds options for all the below mentioned configurations and
subsequently renames the include/configs/spearxxx.h files to spear3xx_evb.h,
spear6xx_evb.h etc to depict evaluation board configuration.SPEAr3xx and SPEAr6xx boards can be compiled in following configurations
1. Environment placed in NAND
2. Console on usb device
3. Console on usb device with environment placed in NAND
4. SPEAr310 and SPEAr320 support environment variables in parallel
NOR flash.Signed-off-by: Vipin Kumar

While the u-boot code is running from the flash, it is essential that no access
is made to the bss segment. This is due to the fact that .rel.dyn and .bss areas
overlap and former contains information used in relocation. In SPEAr, this was
not taken into consideration. As a result, while the relocation wasn't complete,
dram_init populated an uninitialized global variable resulting in corruption of
.rel.dyn area, which resulted in u-boot crash.This commit fixes this problem by removing code that accesses bss segment

The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used. Punt them all.MAKEALL didn't report any errors related to this that I could see.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.Signed-off-by: Sebastien Carlier

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.Signed-off-by: Wolfgang Denk

Lots of code use this construct:
cmd_usage(cmdtp);
return 1;Change cmd_usage() let it return 1 - then we can replace all these
ocurrances byreturn cmd_usage(cmdtp);
This fixes a few places with incorrect return code handling, too.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {
