+Subject: [PATCH 4/6] MIPS: BCM63XX: provide a MAC address for BCM3368 chips
+
+The BCM3368 SoC uses a NVRAM format which is not compatible with the one
+used by CFE, provide a default MAC address which is suitable for use and
+which is the default one also being used by the bootloader on these
+chips.
