[Qemu-devel] [PATCH for-1.8 0/2 v3] pc: inform SeaBIOS where 64-bit PCI hole begins

[Igor Mammedov]

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

* add fw_cfg 'etc/reserved-memory-end' to allow QEMU reserve
  additional address space before 64-bit PCI hole. Which will be
  need for reserving memory hotplug region in highmem.

v3:
 *  rebased on top of current master (1.7-rc0), wich includes dependency 
    "memory: Change MemoryRegion priorities from unsigned to signed"
 *  s/pcimem64-minimum-address/reserved-memory-end/ per Michael suggestion

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

  pc: add 'etc/reserved-memory-end' fw_cfg interface for SeaBIOS

  pc: map PCI address space as catchall region for not mapped addresses
