Allows the BCMA version of the bgmac driver to obtain MAC address
from the device tree. If no MAC address is specified there, then
the previous behavior (obtaining MAC address from SPROM) is
used.

PS: you might want to specify which tree this applies to by using [PATCH
net-next] or [PATCH net] in the subject, see the netdev-FAQ.txt for
