From: Florian Fainelli Date: Wed, 12 Jun 2013 19:53:05 +0000 (+0100) Subject: bcm63xx_enet: add support Broadcom BCM6345 Ethernet X-Git-Tag: v3.11-rc1~16^2~85 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3dc6475c0c9e55ac7f053ad6b8b398e779954545;p=pandora-kernel.git bcm63xx_enet: add support Broadcom BCM6345 Ethernet 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.
