I would prefer if you removed these unneeded parentheses here:

#define CONFIG_SPEAR_ETHBASE			0xE0800000

Perhaps best done by doing a cosmetic cleanup patch before the newly added 
defines. I know that checkpatch doesn't complain about this, but these 
parentheses really distract me. Not sure how other feel about it.

This routine is added multiple times in this patch. Perhaps this can be moved 
to a "common/" file instead?

Again, please remove these parentheses.
