Bjorn,

I haven't seen any feedback on this revision of the patch set.

Are there any remaining issues that you are aware of that are blocking these?

Thanks in advance,
David Daney

Some Cavium ThunderX processors require quirky access methods for the
config space of the PCIe bridge.

There are now three patches:

1) Refactor code in pci-host-generic so that it can more easily be
    used by other drivers.  This splits the driver for CAM and ECAM
    access methods to a separate file from the common host driver code.

2) Add the ThunderX PCIe driver to external PCIe buses, which
    leverages the code in pci-host-generic

3) Add ThunderX PCI driver for internel SoC buses used on early
    ThunderX chip revisions.

Changes from v5: Added Acked-by Rob Herring for the device tree
binding in 3/3.  Fixed typo and split large functions as suggested by
Bjorn Helgaas.

Changes from v4: Added patch 3/3.  Stylistic changes to 2/3 suggested
by Bjorn Helgaas.  When expanding config write width to 32-bits, mask
out unintened writes to W1C bits, also suggested by Bjorn Helgaas.

Changes from v3: Add some Acked-by, rebased to v4.5.0-rc1

Changes from v2: Improve device tree binding example as noted by Rob
Herring.  Rename pcie-thunder-pem.* to pci-thunder-pem.* for better
consistency.  Update MAINTAINERS to reflect the changes.

Changes from v1: Split CAM and ECAM code from common driver code as
suggested by Arnd Bergmann.  Fix spelling errors in
pcie-thunder-pem.txt

David Daney (3):
   PCI: generic: Refactor code to enable reuse by other drivers.
   pci, pci-thunder-pem: Add PCIe host driver for ThunderX processors.
   pci, pci-thunder-ecam: Add driver for ThunderX-pass1 on-chip devices
