Subject: [PATCH 2/6] bcm63xx_enet: do not write to random DMA channel on
|
|
BCM6345
|
|
|
|
The DMA controller regs actually point to DMA channel 0, so the write to
|
|
ENETDMA_CFG_REG will actually modify a random DMA channel.
|
|
|
|
Since DMA controller registers do not exist on BCM6345, guard the write
|
|
with the usual check for dma_has_sram.
