 From the functionality point of view this series might be split into the
following logic parts:
1. Make MMCONFIG code arch-agnostic which allows all architectures to
collect
    PCI config regions and used when necessary.
2. Move non-arch specific bits to the core code.
3. Use MMCONFIG code and implement generic ACPI based PCI host
controller driver.
4. Enable above driver on ARM64

Patches has been built on top of 4.4 and can be found here:
git at github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v3)

NOTE, this patch set depends on Matthew's patches:
http://www.spinics.net/lists/linux-pci/msg45950.html
https://github.com/Vality/linux/tree/pci-fixes

This has been tested on Cavium ThunderX server and QEMU.
Any help in reviewing and testing is very appreciated.

v2 -> v3
- fix legacy IRQ assigning and IO ports registration
- remove reference to arch specific companion device for ia64
- move ACPI PCI host controller driver to pci_root.c
- drop generic domain assignment for x86 and ia64 as I am not
   able to run all necessary test variants
- drop patch which cleaned legacy IRQ assignment since it belongs to
   Mathew's series:
   https://patchwork.ozlabs.org/patch/557504/
- extend MCFG quirk code
- rebased to 4.4

Tested this patch set (and Matthew's) on a HP RX2660 IA64 machine,
with the CONFIG_ACPI_PCI_HOST_GENERIC disabled on IA64 ( it's a minor
comment needs to be addressed in my previous email), it can boot
the system ok with NIC working properly, with the /pro/ioports [1] and
the boot log [2] if anyone needs refer to it.

For this patch set, on IA64 machine,

Tested-by: Hanjun Guo <redacted>

I tested this patch set on x86 server with CONFIG_ACPI_PCI_HOST_GENERIC
disabled today, also booted ok with NIC working properly.

Thanks
