For current mx51 support in u-boot where we have no fuse support the patch is useful. I don't recall what the general policy is in u-boot for env vs eeprom mac addresses but I do remember discussions about it.

Applied, thanks.
Ben, I hope this is OK with you.
In fact, I don't think it's a good fix to fec-mac-address-not-set issue, it's just a hack. This is the output from bootup log,
Warning: FEC MAC addresses don't match: Address in SROM is 75:6e:20:62:6f:6f Address in environment is 00:01:02:04:05:06
It will give one confused warning that the FEC MAC has been set in the SROM, but actually, this the float value which induced by this patch.
In fact, we need read the mac address from FUSE(IIM), all the MAC address has burned into fuse after the chip has been shipped out.
I will send out one patch to fix this issue soon.
Best regards,
Wolfgang Denk
