Subject: [PATCH v7 0/4] Prerequisites for Cavium OCTEON-III network driver.

We want to add 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?  These are the
prerequisite patches that are needed before the network driver can be
merged.

Changes in v7:

o Splitting of the patch set only.  These 4 mips patches are unchanged
  from the previous posting.

Changes in v6:

o Added back cleanup patch for previous generation SoC "staging"
  driver, as Greg K-H acked it.

o Moved FPA driver to drivers/net/ethernet/cavium/octeon as it is
  currently only used by the octeon3-ethernet driver.

o Many code formatting fixes as noted by davem.

Changes in v5:

o Removed cleanup patch for previous generation SoC "staging" driver,
  as it will be sent as a follow-on.

o Fixed kernel doc formatting in all patches.

o Removed redundant licensing text boilerplate.

o Reviewed-by: header added to 2/7.

o Rewrote locking code in 3/7 to eliminate inline asm.

Changes in v4:

o Use phy_print_status() instead of open coding the equivalent.

o Print warning on phy mode mismatch.

o Improve dt-bindings and add Acked-by.

Changes in v3:

o Fix PKI (RX path) initialization to work with little endian kernel.

Changes in v2:

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 (2):
  MIPS: Octeon: Enable LMTDMA/LMTST operations.
  MIPS: Octeon: Add a global resource manager.

David Daney (2):
  MIPS: Octeon: Automatically provision CVMSEG space.
  staging: octeon: Remove USE_ASYNC_IOBDMA macro.
