I looked at the patch and I have a couple comments:

1. The loop that overwrites the b_enetaddr[] should check that it does not
contain any information before assigning the default. This could have been
passed in by the bios.

2. If you assume that any platform that uses CONFIG_EMBEDDEDBOOT may want to
pass in a bd_info structure, then the platform specific patch in head.S is
wrong. Based on the current architecture I believe this is a safe
assumption. You may totally ignore this parameter in embed_config.c where
the platform dependent code is located.
