I mentioned earlier that grepping OvmfPkg for PCI_LIB_ADDRESS would be
necessary. See PciInitialization() in
"OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c".

  //
  // Bus 0, Device 1, Function 0 - PCI to ISA Bridge
  //
  PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x3c), 0x00);
  PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x60), 0x0b); // LNKA routing target
  PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x61), 0x0b); // LNKB routing target
  PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x62), 0x0a); // LNKC routing target
  PciWrite8 (PCI_LIB_ADDRESS (0, 1, 0, 0x63), 0x0a); // LNKD routing target

This is not appropriate for q35. See "ICH9 PCI to ISA irq remapping" in
qemu's "q35-acpi-dsdt.dsl" file, vs. "PIIX PCI to ISA irq remapping" in
"acpi-dsdt.dsl".

The above was added in 05c89c7f.

Thanks
Laszlo
