Hopefully the lesson on custom ATAGs has been learned and we don't
repeat it with something custom and undocumented in DT. I don't want
to hear "we're already using this binding in our bootloader and can't
change it". This example doesn't apply to MAC addresses since there
already is a defined way, but I'm sure there are other examples. That
is what I've gotten from the OLPC folks before.
