+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.
