Hello Adrian,
This 'uboot' label was used only for MAC address extraction from
u-boot partition (kinda strange, I couldn't find a clue why it was
expected there), so I decided to remove it.

Nope, it should be calculated. In theory, according to Netgear uboot
sources, it should be in ART region at 0x108c but in all devices I
could inspect that area was empty (0xff). ar71xx target also derives
wlan0 MAC from ethX MACs.

MAC addresses for all interfaces are correctly assigned with this
patchset in place (tested), so apparently nothing interferes here.
