MAC address passing from U-Boot to Linux hjas nothing to do with  the
PHY  used.  In  2.4  you're  using the bd_info structure to pass this
information. Your Linux network driver should pick it  up  there;  in
2.6,  you  should  use  the  device  tree - again, your Linux network
driver should know where it can find the MAC addresses.

Best regards,
