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 4.5-rc3 and can be found here:
git@github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v5)

NOTE, this patch set depends on Lorenzo's fixes:
https://patchwork.ozlabs.org/patch/576450/
which can be found in pci-acpi-v5 branch.

This has been tested on Cavium ThunderX server, JunoR2, HP RX2660 IA64, x86,
Hip05, X-Gene and QEMU-aarch64. Any help in reviewing and testing is very appreciated.

v4 -> v5
- dropped MCFG refactoring group patches 1-6 from series v4 and integrated Jayachandran's patch
  https://patchwork.ozlabs.org/patch/575525/
- rewrite PCI legacy IRQs allocation
- squashed two patches 11 and 12 from series v4, fixed bisection issue
- changelog improvements
- rebased to 4.5-rc3

v3 -> v4
- dropped Jiang's fix http://lkml.iu.edu/hypermail/linux/kernel/1601.1/04318.html
- added Lorenzo's fix patch 19/24
- ACPI PCI bus domain number assigning cleanup
- changed resource management, we now claim and reassign resources
- improvements for applying quirks
- dropped Matthew's http://www.spinics.net/lists/linux-pci/msg45950.html dependency
- rebased to 4.5-rc1

Having tested v4 and v5, I'm seeing some resource assignment problems and address conflicts. 
And problems booting QEMU.

Anybody else seeing the same?
