[PATCH v9 0/2] adding PCI support to AXS10x

[Joao Pinto]

This patch set has the goal to add suppport for DesignWare PCIe RC in ARC
AXS10x. It includes the necessary tweaks to:
 - the ARC architecture (PCI support)
 - the PCI subsystem (ARC CPU support)
 - to pcie-designware (Centralisation of wait for link routine)
 - to dra7xx, exynos, imx6 and spear13xx drivers to use the centralised
 code for link wait

A simple module was (pcie-designware-plat) was created to contain the 
specific platform init code.

The patches were produced against Bjorn Helgaas' repository. It was properly
tested in an IP Prototyping Kit.
