[PATCH 0/4] PCI: X-Gene: Add APM X-Gene v1 MSI/MSIX termination driver

[Duc Dang]

This patch set adds MSI/MSIX termination driver support for APM X-Gene v1 SoC.
APM X-Gene v1 SoC supports its own implementation of MSI, which is not compliant
to GIC V2M specification for MSI Termination.

There is single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports. This MSI
block supports 2688 MSI termination ports coalesced into 16 physical HW IRQ lines 
and shared across all 5 PCIe ports.
