From: David Daney <david.daney@xxxxxxxxxx> 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.
