From: Kumar Gala @ 2008-08-19 20:41 UTC (permalink / raw)
  To: u-boot

Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.

This makes the code a bit more flexible to the number of ethernet
interfaces.

Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Bump the array sizes to cover a vast number of ethernet mac addresses
at Wolfgang's request.
