bcm63xx_enet: add support Broadcom BCM6345 Ethernet

2013-06-14T00:22:08Z

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.

bcm63xx_enet: add support for Broadcom BCM63xx integrated gigabit switch

2013-06-10T21:28:28Z

Newer Broadcom BCM63xx SoCs: 6328, 6362 and 6368 have an integrated switch which needs to be driven slightly differently from the traditional external switches. This patch introduces changes in arch/mips/bcm63xx in order to: - register a bcm63xx_enetsw driver instead of bcm63xx_enet driver - update DMA channels configuration & state RAM base addresses - add a new platform data configuration knob to define the number of ports per switch/device and force link on some ports - define the required switch registers On the driver side, the following changes are required: - the switch ports need to be polled to ensure the link is up and running and RX/TX can properly work - basic switch configuration needs to be performed for the switch to forward packets to the CPU - update the MIB counters since the integrated Signed-off-by: Maxime Bizon Signed-off-by: Jonas Gorski Signed-off-by: David S.

MIPS: BCM63XX: Move DMA descriptor definition into common header file

2012-08-30T18:15:52Z

The "IUDMA" engine used by bcm63xx_enet is also used by other blocks, such as the USB 2.0 device. Move the definitions into a common file so that they do not need to be duplicated in each driver.
