This is not related to meta-fsl-arm, so it would be better to post
U-boot related questions into the U-boot list.
By default the MAC address is read from the fuses in mainline U-boot.
If you delete the ethaddr manually, ie: 'setenv ethaddr', then you
will notice that during the next boot the ethaddr will be read from
the fuses and then stored into the SD card.
