On my little endian PXA270, the ethernet address is byte swapped:
correct ethernet address: 00:50:c2:80:a7:bd
broken ethernet address: 50:00:80:c2:bd:a7
The correct value is what the sticker on the baoard and the linux driver
says. This patch fixes the problem by reading the ethaddr byte-wise from
the eeprom.
