Actually the smc91111.c driver does something of the sort. See the
function get_rom_mac(). This is a very simplistic approach and it is
also invisible to the overall uboot structure. Maybe you can live with
such an approach?

Many embedded boards, however, will store their MAC address simply in
the global environment, so that's probably the reason why you don't
find what you're looking for.
