[Qemu-devel] [PATCH 0/2 v2] pc: inform SeaBIOS where 64-bit PCI hole begins

[Igor Mammedov <imammedo@redhat.com>]

* simplify PCI address space mapping into system address space,
  replacing code duplication in piix/q53 PCs with a helper function

* add fw_cfg 'etc/pcimem64-minimum-address' to allow QEMU reserve
  additional address space before 64-bit PCI hole. Which will be
  need for reserving memory hotplug region in highmem.
  SeaBIOS counterpart: http://patchwork.ozlabs.org/patch/283623/

v2:
 *  use negative priority to map PCI address space under RAM memory
    regions which allows simplify code by removing pci_hole &
    pci_hole64 memory region aliases

Series depends on:
 "memory: Change MemoryRegion priorities from unsigned to signed:
