+Subject: [PATCH 2/7] ARM: atags/fdt: retrieve MAC addresses from Marvell boot
+ loader
+
+The atags are parsed and if a Marvell atag is found, up to 4 MAC
+addresses are extracted there and assigned to node aliases eth0..3
+with the name "mac-address".
+
+This was tested on my Mirabox and the two NICs had their correct
+address set.
