- Fix EEPROM_data structure definition according to System EEPROM Data Format. - Read MAC addresses from EEPROM to ethXaddr before saving ethXaddr to bd->bi_ethaddr.
Signed-off-by: Haiying Wang Haiying.Wang@freescale.com ---
This patch was only tested on MPC8641HPCN board, but it is supposed to work for all NXID boards. Please help to verify if possible.
