From: Suravee Suthikulpanit <Suravee.Suthikulpanit@amd.com>

This is an RFC to introduce support for AMD Seattle ARM64 platform.

It is also intended to provide support for validating Liviu's PCI patch series:
[PATCH v12 00/12] Support for creating generic PCI host bridges from DT
https://lkml.org/lkml/2014/9/23/852

It is also intended to provide support for validating GICv2m patch series
(w/o multi-MSI).

Overview:

* Patch 1 adds AMD Seattle device tree (w/ PCI and MSI support)

* Patch 2-3) adds ARM64 and MSI support to the existing Generic PCI
host controller.

* Patch 4 comes from the GICv2m patch series:
[V8 2/2] irqchip: gicv2m: Add supports for ARM GICv2m MSI(-X)
(https://lkml.org/lkml/2014/9/20/113)

It has been slightly modified to remove the multi-MSI supports for now
(awaiting discussion with other maintainers), and will be submitted
separately.

Suravee Suthikulpanit (4):
arm64: amd-seattle: Adding device tree for AMD Seattle platform
PCI: generic: Add support for ARM64 and MSI(x)
arm64: Do not call enable PCI resources when specify PCI_PROBE_ONLY
irqchip: gicv2m: Add supports for ARM GICv2m MSI(-X)
