e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
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.

461be2f96e kconfig: remove redundant "string" type in arch and board Kconfigs
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//
}
'

93d4334f7f Add board MAINTAINERS files
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.

dd84058d24 kconfig: add board Kconfig and defconfig 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/.

9c653aad16 drivers: net: cpsw: add support to have phy address from cpsw platform data
Some platforms like AM437x have different EVMs with different phy addresses,
so this patch adds support for passing phy address via cpsw plaform data.
Also renamed phy_id to phy_addr so better understanding of the code.

7aecdb07a5 pcm051: Support for revision 3
Phytec sells revision or version 3 of pcm051. It is labeled 1358.3 on
the board. The difference for u-boot is that is has other DDR3 RAM on it:
1 x MT41K256M16HA125E instead of 2 x MT41J256M8HX15E on revisions 1 and
2. Both configurations are 512 MiB.
Configure your u-boot build with pcm051_rev3 for the new RAM and
pcm051_rev1 for the old RAM configuration. Board revision 2 has to use
pcm051_rev1 also.

6d8962e814 Switch from archive libraries to partial linking
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.
