Traditional q35 memory layout is 2.75 GB of low memory, leaving room for the pcie mmconfig at 0xb0000000 and the 32-bit pci mmio window at 0xc0000000. Because of that OVMF tags the memory range above 0xb0000000 as uncachable via mtrr. A while ago qemu started to gigabyte-align memory by default (to make huge pages more effective) and q35 uses only 2G of low memory in that case. Which effectively makes the 32-bit pci mmio window start at 0x80000000. This patch updates the mtrr setup code accordingly.
