* 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:
