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" Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@14837 6f19259b-4bc3-4df7-8a09-765794883524
