[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.
