This test is similar to the actual POST memory test but quicker and
far less complete. It checks the address and data lines and then only
tests some regularly placed sub regions of the RAM.
This can be useful when we want to test the RAM but we do not have enough
time to run the full memory test.
The POST memory test code was rearranged in order to avoid code duplication
between the two tests but the memory test functionnality remains the same.

This is needed for a further patch adding a new memory test.

change bd->bi_memsize to gd->ram_size, as this is defined
on all archs, so this post test can used on none powerpc
archs too.

Add weak functions to enable architecture depended preparation, address
advancing, cleaning up and error handling.
These weak functions provides the framwork to implemente arch/platform
dependent code for initializing/maintenance/restore the start address, size,
physical address as well as memory mapping before/between/after memory test.
arch_memory_failure_handle can also be implemented in case more care is needed
for arch/platform.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

As experienced on lwmon5, on some boards the POST memory test can
corrupt the global data buffer (bd). This patch fixes this issue
by checking and limiting this area.
