The board select menu in arch/arm/Kconfig is still big.
To slim down it, this commit moves AT91 boards to
arch/arm/mach-at91/Kconfig.
Also, consolidate "config SYS_SOC" in each board Kconfig.
The Kconfig files under board/ directory were modified with the
following command:
find board -name Kconfig | xargs sed -i -e '
/config SYS_SOC/ {
N
/default "at91"/ {
N
d
}
}
'

This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.
For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.
Also, it removes redundant "string" type in some Kconfig files.

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.
We can delete the ones in arch and board Kconfig files.
This commit can be easily reproduced by the following command:
find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
N
s/\n[[:space:]]*string//
}

We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.
The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.
After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.
TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

On at91sam platforms, u-boot grew larger than the allocated size in
dataflash, the layout was:
bootstrap 0x00000000
ubootenv 0x00004200
uboot 0x00008400
kernel 0x00042000
fs 0x00252000
u-boot with the defconfig doesn't seem to fit in 0x42000 - 0x8400 =
0x39C00 bytes anymore.
Now, the layout is:
bootstrap 0x00000000
ubootenv 0x00004200
uboot 0x00008400

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.

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.

AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed.
The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board.
It is essentially the same, with a few minor differences.

AT91 RSTC registers are battery-backuped, so their values
are not reset across power cycles. One of those registers,
the AT91_RSTC_MR register, is being modified by U-Boot, in
the ethernet initialisation routine, to generate a 500ms
user reset.
Unfortunately, this value is not being restored afterwards,
causing subsequent resets to also last for 500ms.
This long reset sequence causes problems (at least) in the
boot sequence from NOR: by the time the CPU tries to load
a program from the NOR flash, the latter is still in reset
and not yet available.
Additionaly, this patch fixes a bug in the original code which
caused the reset delay to last for 2s instead of 500ms.
