We are adding the Cavium OCTEON-III network driver. But since
interacting with the input and output queues is done via special CPU
local memory, we also need to add support to the MIPS/Octeon
architecture code. Aren't SoCs nice in this way?
The first six patches add the SoC support needed by the driver, the
last two add the driver and an entry in MAINTAINERS.
Since these touch several subsystems (mips, staging, netdev), I would
propose merging via netdev, but defer to the maintainers if they think
something else would work better.
A separate pull request was recently done by Steven Hill for the
firmware required by the driver.
Changes from v2:
o Fix PKI (RX path) initialization to work with little endian kernel.
Changes from v1:
o Cleanup and use of standard bindings in the device tree bindings
document.
o Added (hopefully) clarifying comments about several OCTEON
architectural peculiarities.
o Removed unused testing code from the driver.
o Removed some module parameters that already default to the proper
values.
o KConfig cleanup, including testing on x86_64, arm64 and mips.
o Fixed breakage to the driver for previous generation of OCTEON SoCs (in
the staging directory still).
o Verified bisectability of the patch set.
Carlos Munoz (5):
dt-bindings: Add Cavium Octeon Common Ethernet Interface.
MIPS: Octeon: Enable LMTDMA/LMTST operations.
MIPS: Octeon: Add a global resource manager.
MIPS: Octeon: Add Free Pointer Unit (FPA) support.
netdev: octeon-ethernet: Add Cavium Octeon III support.
David Daney (3):
MIPS: Octeon: Automatically provision CVMSEG space.
staging: octeon: Remove USE_ASYNC_IOBDMA macro.
