X-Gene PCIe controllers support huge outbound BARs (with size upto
64GB). This patch configures additional 1 outbound BAR for X-Gene
PCIe controllers with size larger than 4GB. This is required to
support devices that request huge outbound memory (nVidia K40 as an
example)

The PCI specs don't use the "outbound BAR" terminology.  I assume this
is what we normally call "windows" or "apertures" for MMIO access by
the CPU?  (The specs rarely use those terms either, but they're
commonly used in Linux, and the PCIe spec does mention them a couple
times.)

By "request huge outbound memory," I assume you simply mean the device
has a huge BAR, right?
