3beb40c247 85xx: Ensure BSS segment isn't linked at address 0
When U-Boot is relocated from flash to RAM pointers are modified
accordingly.  However, pointers initialzed with NULL values should not
be modified so that they maintain their intended NULL value.  If the
BSS segment is linked at address 0 its address will not be
updated as necessary during relocation.

This is a temporary workaround.  The end goal is to add support to
U-Boot to dynamically locate the BSS at an arbitrary address at
runtime.  When the ability to fixup the BSS inteligently is
added, this workaround can be removed and the 85xx link script
can put the BSS at a fixed address at link time.

858290178f ppc: Enable full relocation to RAM
The following changes allow U-Boot to fully relocate from flash to
RAM:
 - Remove linker scripts' .fixup sections from the .text section
 - Add -mrelocatable to PLATFORM_RELFLAGS for all boards
 - Define CONFIG_RELOC_FIXUP_WORKS for all boards

Previously, U-Boot would partially relocate, but statically initialized
pointers needed to be manually relocated.

6c97a20d0b ppc/85xx: Introduce RESET_VECTOR_ADDRESS to handle non-standard link address
Some board ports place TEXT_BASE at a location that would cause the
RESET_VECTOR_ADDRESS not to be at 0xfffffffc when we link.  By default
we assume RESET_VECTOR_ADDRESS will be 0xfffffffc if the board doesn't
explicitly set it.

ec79d33b2c 85xx: Move to a common linker script
There are really no differences between all the 85xx linker scripts so
we can just move to a single common one.  Board code is still able to
override the common one if need be.
