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.

Hi Arnd, Bjorn,

Do you have additional comment on this v2 patch set?

The changes look ok to me now, but I'd mention in the changelog about
the fact that one of the windows is prefetchable and the other one
is not, and that only prefetchable BARs are now using the 64-bit
window.
