At present the PCI host bridge (PHB) for the pseries machine type has a fixed DMA window from 0..1GB (in PCI address space) which is mapped to real memory via the PAPR paravirtualized IOMMU. For better support of VFIO devices, we're going to want to allow for different configurations of the DMA window. Eventually we'll want to allow the guest itself to reconfigure the window via the PAPR dynamic DMA window interface, but as a preliminary this patch allows the user to reconfigure the window with new properties on the PHB device.
