2013-07-22bcma: fix handling of big addrlHauke Mehrtens1-8/+8
The return value of bcma_erom_get_addr_desc() is a unsigned value and it could wrap around in the two complement writing. This happens for one core in the BCM4708 SoC. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

It is better to return the actual error code than just -1. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

The e1000e conflict is an addition of a new statistic in the ethtool code, trivial. The vmxnet3 conflict is about one change in 'net' removing a guarding conditional, whilst in 'net-next' we had a netdev_info() conversion. The iwlwifi conflict is dealing with a WARN_ON() conversion in 'net-next' vs. a revert happening in 'net'. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-01-14bcma: add support for 1 and 2 byte extended config space accessNathan Hintz1-7/+8
The sanity checks allow 1 and 2 byte reads/writes of the extended PCI config space to proceed; however, the code only supports 4 byte reads/writes.

2013-01-14bcma: don't map/unmap a subset of the PCI config spaceNathan Hintz1-11/+11
For PCI config space access offsets < 256 for device '0', bcma_extpci_write_config performs an 'ioremap_nocache' on a 4 byte section of the PCI config space (an area that has already previously been mapped), and then subsequently unmaps that 4 byte section. This can't be a good thing for future read access from that now unmapped location. Modify the config space writes to use the existing access functions (similar to how it is done for the reads).

2013-01-09bgmac: driver for GBit MAC core on BCMA busRafał Miłecki1-1/+2
BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA based SoCs have gigabit ethernet provided by the GBit MAC core. This patch adds driver for such a cores registering itself as a netdev. It has been tested on a BCM4706 and BCM4718 chipsets. In the kernel tree there is already b44 driver which has some common things with bgmac, however there are many differences that has led to the decision or writing a new driver: 1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44) 2) There is 64bit DMA engine which differs from 32bit one 3) There is no CAM (Content Addressable Memory) in GBit MAC 4) We have 4 TX queues on GBit MAC devices (instead of 1) 5) Many registers have different addresses/values 6) RX header flags are also different The driver in it's state is functional how, however there is of course place for improvements: 1) Supporting more net_device_ops 2) SUpporting more ethtool_ops 3) Unaligned addressing in DMA 4) Writing separated PHY driver Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: David S.
