Rather than __bss_end, define a new symbol which sets the end boundary of
code to be relocated by relocate_code(). This allows us to add code after
the BSS section which is still relocatable.

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.

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.

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.

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.

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.
