+[PATCH] MIPS: BCM63XX: enable ethernet for BCM6345
+
+BCM6345 has a slightly older DMA engine which is not supported by default by
+the bcm63xx_enet driver. This patch adds the missing Ethernet DMA definitions
+as well as patches all the places in the ethernet driver were the DMA
+reading/writing is different.
