The Zynq driver attachment currently takes the mac address from
the dtb key 'local-mac-address'.

The driver itself will fall back to a hardcoded address when
no such key was set. That's unfortunate, it should be able
to read out an already configured address and keep it (like
other drivers do). Then u-boot could just configure the
hardware.

Another possibility is for u-boot to modify the dtb.
