[PATCH v2 0/2] pci: xgene: Add multiple memory ranges support

From: Duc Dang <hidden>
Date: 2015-06-30 18:23:24
Also in: linux-devicetree, linux-pci, lkml

This patch set adds 1 large (up to 64GB) memory window for each PCIe
controller nodes in X-Gene device tree and fix PCIe controller driver
to handle multiple memory ranges correctly. These changes are required
to support PCIe devices that has huge BAR.

v2 changes:
	1. Separate device-tree changes and driver changes into different
	patches
	2. Explicitly define new large window as 64-bit prefetchable in dts
	3. Use IORESOURCE_PREFETCH flag to determine which PCIe controller
	register to be used to configure the memory ranges.
