The patch is to support getting FEC MAC address from fuse bank.

Hi Jason,
I applied your patch and I tested on a i.MX27 Lite board. The result does not seem correct. According to the manual, the mac address is store at address 0x10028814. Rather there is no stored MAC at this address on my board, but your patch read the MAC from address 0x10028810 (I traced the address of fuse->mac_addr).
The reported address is what we can see at 0x10028810 (Word 4 of fusebank 0):
md 0x10028804 10028804: 00000020 00000081 00000040 00000010 .......@....... 10028814: 00000000 00000000 00000000 00000000 ................
And u-boot reports : Address in SROM is 00:00:00:00:00:10 Address in environment is 00:aa:dd:cc:11:22
It seems you read at a wrong address.
I think you are right. I did not have the mx27 board to do test. Thanks for test.
I only test it on mx51babbage board, the following is the output:
Net: got MAC address from fuse: 00:04:9f:00:f7:78 which is the same as the MAC address programmed on the board.
Do you have any other comments about this patch?
BR, Jason
Best regards, Stefano Babic
