Hi Ray,
The patches work for OVMF/Xen. The system booted into OS without
problem. However, With OVMF/KVM, I got this:
[...]

QemuFwCfg interface is supported.
Select Item: 0x19
InitRootBridge: populated root bus 0, with room for 255 subordinate bus(es)
RootBridge: PciRoot(0x0)

DmaAbove4G: No

Mem: 90000000 - FBFFFFFF
MemAbove4G: 800000000 - FFFFFFFFF

/home/gary/git/edk2/MdeModulePkg/Bus/Pci/PciHostBridgeDxe/PciRootBridgeIo.c(116):
Bridge->PMemAbove4G.Base >= 0x0000000100000000ULL
Would you mind to check it?
