[PATCH v3 0/5] PCI: hisi: Add PCIe host support for Hisilicon Soc Hip05

[Zhou Wang]

This patchset adds PCIe host support for Hisilicon Soc Hip05. The PCIe hosts
use PCIe IP core from Synopsys, So this driver is base on designware PCIe driver.

Hip05 is an ARMv8 architecture Soc. It should be able to use ARM64 PCIe API in
designeware PCIe driver. So this patch also adds ARM64 support for designware
pcie.

I tested this patchset on D02 board of Hisilicon with Intel 82599 networking
card. It works well.

This patchset is based on v4.1-rc8.

Change from v2:
- move struct pci_dev *dev and struct pci_sys_data *sys in
  pcibios_align_resource in 1/5.
- Add Gabriele's codes in 2/5 which delete unnecessary information parse and
  use of_pci_get_host_bridge_resources for both ARM32 and ARM64.
- Add maintainer patch 5/5.

Change from RFC v1:
- Add 1/4 patch by Arnd which removes align_resource callback in ARM
  pcibios_align_resource.
- Change head file in pcie-designware from asm/hardirq.h to linux/hardirq.h.
- Set pp->root_bus_nr = 0 in dra7xx, exynos, imx6, keystone, layerscape,
  spear13xx.
- Remove unnecessary parentheses of some macros in pcie-hisi.
- Use macro to replace some magic values.
- Merge two loops together and add some comments about it in context_config
  function in pcie-hisi.
- Modify some value of items in pcie node example in binding document. 

Change from RFC:
- delete dw_pcie_setup, dw_pcie_scan_bus, dw_pcie_map_irq and struct hw_pci,
  merge related operations into dw_pcie_host_init.
