033ca72438 armv7: start.S: fixes and enhancements for SPL
- Allow SPL to have .bss disjoint from rest of the image
- Allow for .bss setup in CONFIG_SPL_BUILD case too.
- Take care of the special case where relocation offset = 0.
- Compile out exception handling code and install a simpler
  vector

f326cbba98 arm: fix incorrect monitor protection region in FLASH
Monitor protection region in FLASH did not cover .rel.dyn
and .dynsym sections, because it uses __bss_start to compute
monitor_flash_len. Use _end instead.

Add _end to linker scripts for end of u-boot image
Add _end_ofs to all the start.S.

44c6e6591c rename _end to __bss_end__
Currently, _end is used for end of BSS section.  We want _end to mean
end of u-boot image, so we rename _end to __bss_end__ first.

aaeb0a890a ARM: fix linker file for newer ld support
older ld emitted all ELF relocations in input sections named
.rel.dyn, whereas newer ld uses names of the form .rel*. The
linker script only collected .rel.dyn input sections. Rewrite
to collect all .rel* input sections.

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.

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.
