Thu Apr 30 16:31:41 EDT 2015
The ability to read MAC addresses from MTD is useful for other targets besides
ramips and lantiq as well.

+Subject: 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.
