9d86f0c30b kirkwood: make MPP arrays static const
This saves stack and code memory for local copy, and
consumes initialized data memory. For 22 of the 29
kirkwood-based boards, this results in a global saving
of about 30 bytes. For 7 of them, it results in an
increase of 6 to 14 bytes.

b3168f4be8 kirkwood: implement kw_sdram_size_adjust
Size of the SDRAM chips might differ between any two (otherwise
identical) instances of the same board.

So add a function kw_sdram_size_adjust() which reads out the current
ram size for a given bank, and adjusts the Kirkwood's SDRAM window size
register accordingly.

4551516525 kirkwood: implement kw_sdram_bs_set()
Some boards might be equipped with different SDRAM configurations.
When that is the case, CPU CS Window Size Register (CS[0]n Size)
should be set to the biggest value through board.cfg file; then its
value can be fixed at runtime according to the detected SDRAM size.

Therefore, implement kw_sdram_bs_set().

8f5d7a0398 kirkwood: add save functionality kirkwood_mpp_conf function
If a second non NULL argument is given to the kirkwood_mpp_conf
function, it will be used to store the current configuration of the MPP
registers. mpp_save  must be a preallocated table of the same size as
mpp_list and it must be zero terminated as well.

A later call to kirkwood_mpp_conf function with this saved list as first
(mpp_conf) argment will set the configuration back.

5307153236 Stop using builtin_run_command()
Boards can select either the 'built-in' parser or the hush parser. We
should not call builtin_run_command() if we are using the hush parser.
We use run_command() instead, since it knows how to call the correct
parser.

f47360a74e Rename run_command() to builtin_run_command()
The current run_command() is only one of the parsing options - the other
is hush. We should not call run_command() when the hush parser is being
used. So we rename this function to better explain its purpose.

a7efd719f4 ARM: kirkwood: reduce dependence of including platform file
For files like the drivers/serial/serial.c, it must include the
platform file, as the CONFIG_SYS_NS16550_COM1 must reference to the
definition in the platform definition files.

Include the platform definition file in the config file, so that it
would decouple the dependence for the driver files.

2e0c1c7d5c dreamplug: initial board support.
Copied wholeheartedly from board/Marvell/guruplug and modified to add support
for SPI NOR flash.

CONFIG_MACH_DREAMPLUG defined in include/configs/dreamplug.h until Linus's
kernel.org tree adds it to mach-types.h.  Once it trickles down, the definition
can be removed from include/configs/dreamplug.h.

c9ac3ba129 arm926ejs: timer: Replace bss variable by gdr
Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss
values in the arm926ejs timers implementation.

The usage of bss values in drivers before initialisation of bss is forbidden.
In that special case some data in .rel.dyn gets corrupted.

This patch is similiar to the patch Dirk Behme posted
for the armv7/omap-common/timer.c and added suggestions
from Reinhard Meyer.

Tested on the arm926ejs mx27 based magnesium board
Tested on the arm926ejs kirkwood based suen3 board

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.

28e57108a6 Kirkwood: bugfix: DRAM size initialization
If start of any DRAM bank is greater than total DDR size, remaining DDR banks' start address & size were left un-initialized in dram_init function. This could break other functions who uses array 'gd->bd->bi_dram'. Kirkwood network driver is one example. This also stops Linux kernel from booting.

v2 - Set start address also to 0. Without this Linux kernel couldn't
     boot up

beeb258976 Kirkwood: dram_init is moved to dram.c
For all Kirkwood boards so far dram_init function is duplicated
dram_init function is moved to dram.c and relevant code from all
board specific files removed

If any board needs specific dram init handling than standard one,
then, a macro CONFIG_SYS_BOARD_DRAM_INIT should be defined in
board config header file and the dram_init function can be put
in board specific source file
For ex. keymile boards
