If you do use the bmw board as a model, be sure to include your define along with the "#if defined CONFIG_BMW" (in start.S) or you will not "drop" into early_init_f in early_init.S.

The Broadcom BMW board is based on the MPC8245, and it accesses part of that region of memory. You should use that code as an example.
However, I should note that, in U-Boot 1.0.0, the file "board/bmw/early_init.S" does not contain a GPL header.
