+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.

Subject: mpc85xx: replace WDR4900 uci-defaults ethernet MAC address hack with DTS entry
This also changes the MAC address to one of the adresses actually used by the
stock firmware on one of the ethernet interfaces.
