-From: John Crispin <blogic@openwrt.org>
-Subject: NET: add mtd-mac-address support to of_get_mac_address()
-
-Many embedded devices have information such as mac addresses stored inside mtd
-devices. This patch allows us to add a property inside a node describing a
-network interface. The new property points at a mtd partition with an offset
-where the mac address can be found.
