Add support for reading and writing mac addresses to or from ID EEPROM.
Added code for reading and writing Mac addresses to/from ID EEPROM(0x57). With attached patch, we can use command "mac/mac read/mac save/" to read and write EEPROM under u-boot prompt. U-boot will calculate the checksum of EEPROM while bootup, if it is right, then u-boot will check whether the mac address of eTSEC0/1/2/3 is availalbe (non-zero). If there is mac address availabe in EEPROM, u-boot will use it, otherewise, u-boot will use the mac address defined in MPC8641HPCN.h. This matches the requirement to set unique mac address for each TSEC port. Signed-off-by: Haiying Wang <haiying.wang@freescale.com> Signed-off-by: York Sun <yorksun@freescale.com>
