This got broken in committing, due to a catalogue of broken practices.
Firstly, we should *pull* git submissions, never recommit them. You
preserve the correct history then, and don't risk rebasing to result in
a history which *never* worked in the form that gets preserved.
That would have kept the authorship attrbution correct too.
Secondly, we shouldn't be storing CRLF line endings in the objects that
git stores in its database. It is designed to store simple LF line endings,
and then check that out as appropriate for the system (resulting in CRLF
in the working tree for Windows users, as they expect). That would avoid
this problem, and all the other problems we have with patches being

InitRootBridge() in "OvmfPkg/PciHostBridgeDxe/PciHostBridge.c" passes the
EFI_PCI_HOST_BRIDGE_COMBINE_MEM_PMEM allocation attribute to
RootBridgeConstructor(); we should do the same here.
From "MdePkg/Include/Protocol/PciHostBridgeResourceAllocation.h":
/// If this bit is set, then the PCI Root Bridge does not support separate
/// windows for Non-prefetchable and Prefetchable memory. A PCI bus driver
/// needs to include requests for Prefetchable memory in the
/// Non-prefetchable memory pool.
Which implies that both the 32-bit and 64-bit prefetchable MMIO apertures
should be marked empty. (The CreateRootBridge() function actually enforces
this in "MdeModulePkg/Bus/Pci/PciHostBridgeDxe/PciRootBridgeIo.c".)
Furthermore, since OvmfPkg/PciHostBridgeDxe does *not* set the
EFI_PCI_HOST_BRIDGE_MEM64_DECODE allocation attribute:
/// If this bit is set, then the PCI Root Bridge supports 64 bit memory
/// windows. If this bit is not set, the PCI bus driver needs to include
/// requests for 64 bit memory address in the corresponding 32 bit memory
/// pool.
we follow suit in the PciHostBridgeLib instance.
In turn, the 64-bit MMIO apertures (both prefetchable and
non-prefetchable) should be marked empty.
MdeModulePkg/Bus/Pci/PciHostBridgeDxe enforces this too.
(64-bit MMIO aperture support, based on yet more fw_cfg files, is a
planned future improvement.)
