You could just remove the adress paragraph. Same for other places in this patch.

Can't you just remove this get_board_rev() from the board file and use
the generic one instead?

In this file you use multi-line style for single line comments.
You could simply do:
/* U-Boot Commands */

Why do you need such large size?

Are these values correct? You are only testing 64kB of the RAM.
