This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345
has a slightly different and older DMA engine which requires the
following modifications:
- the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes,
which means that the helpers enet_dma{c,s} need to account for this
channel width and we can no longer use macros
- BCM6345 DMA engine does not have any internal SRAM for transfering
buffers
- BCM6345 buffer allocation and flow control is not per-channel but
global (done in RSET_ENETDMA)
- the DMA engine bits are right-shifted by 3 compared to other DMA
generations
- the DMA enable/interrupt masks are a little different (we need to
enabled more bits for 6345)
- some register have the same meaning but are offsetted in the ENET_DMAC
space so a lookup table is required to return the proper offset
The MAC itself is identical and requires no modifications to work.
