OvmfPkg/AcpiPlatformDxe/Qemu: Decrease upper limit for PCI window 32
In a later patch we will want to mark the flash memory as a
runtime services data memory range. This will allow a new runtime
services firmware block driver to read & write flash memory when
the OS has set up virtual memory protection.
Since this memory range will appear as runtime services data, we
need to adjust the limit when scanning for PCI window 32 down to
just below the flash device. If we don't adjust the limit, then
the algorithm in PopulateFwData will fail because it will see a
EfiGcdMemoryTypeSystemMemory memory range just below 4GB.
v2:
* This patch replaces the v1 patch:
"OvmfPkg/AcpiPlatformDxe/Qemu: Allow high runtime memory regions"
