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.
