Wolfgang Denk a9aa392629 Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
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.

Steve Sakoman 136c69ad79 ARMV7: OMAP3: Fix bug in get_sdr_cs_offset()
This patch fixes a typo in the routine to calculate the cs offset
based upon the contents of the SDRC cs_cfg register.  This function
mistakenly shifts the CS1STARTLOW field 17 bits right instead of
17 bits left.

This hasn't been an issue to date because all OMAP3 boards currently
are configured to have zeros in this field.

Heiko Schocher 561142af20 ARM: implement relocation for ARM V7 (OMAP)
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.

Portions of this work were supported by funding from
the CE Linux Forum.

Steve Sakoman 3667cbeed5 ARMV7: OMAP3: Remove erroneous hard coded sdram setup for 128MB/bank
Upcoming Beagle and Overo revisions use POP memory with 256MB or 512MB
per bank.  This patches uses the SDRC settings from x-load or the config
header to set up timing properly.

Steve Sakoman f56348af5d ARM: Rename arch/arm/cpu/arm_cortexa8 to armv7
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.
