The ability to read MAC addresses from MTD is useful for other targets besides ramips and lantiq as well.

-Subject: [PATCH 34/57] NET: add of_get_mac_address_mtd()
-
-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.
