ARM: implement relocation for ARM926
Change the implementation for arm926 to relocate the code to
an arbitrary address in RAM.
Adapt the TX25 (i.MX25), magnesium board to test the changes.
On the tx25 board TEXT_BASE is set to the final relocation
address to prevent one more copying of u-boot code
when relocating. More info see:
doc/README.arm-relocation
