((readl(&emif4_base->sdram_iodft_tlgc) & (1<<10)) == 0x01)
is always false.
This does not match the comment
/*Wait till that bit clears*/

The problem was indicated by cppcheck.

I do not have the hardware to test if the code change below
leads to a correct system behavior.

By making dram_init_banksize() return an error code we can drop the
wrapper. Adjust this and clean up all implementations.

This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories.  All refernces to the former locations are updated to
the current locations.  For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.

With addition of "dram_init_banksize()" function from Heiko,Schocher
(commit ID: 561142af), the DRAM size
is getting configured wrongly to 512Mb (CS0 & CS1).
So fix it to 256Mb.

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support.  However, other recent changes led to a different
implementation (ELF relocation), where this no longer works.  By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

Change the implementation for ARM V7 to relocate the code to an
arbitrary address in RAM.

Adapt the Beagle board (Cortex A8) to test the changes.

The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9

Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.

The two architectures are similar enough that substantial code can be shared.
