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 da850 board: Tested-by: Ben Gardiner <bengardiner@nanometrics.ca> Portions of this work were supported by funding from the CE Linux Forum.
