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:

I boot tested this on JunoR2 with a recent build of Tianocore EDK2.
It works enough to boot the machine with PCIe attached sata, and
ethernet, but is throwing messages like:
[ 1.094643] pci 0000:00:00.0: BAR 13: no space for [io size 0x2000]
[ 1.101022] pci 0000:00:00.0: BAR 13: failed to assign [io size 0x2000]
Its also throwing:
[ 1.029958] pci 0000:00:00.0: of_irq_parse_pci() failed with rc=-22
[ 1.052784] pci 0000:00:00.0: of_irq_parse_pci() failed with rc=-22
(see other response for the DwordIo resource i'm using).
