[SeaBIOS] [PATCH v3 0/2] pci: reserve resources for pcie-pci-bridge to fix regressed hotplug on q35 with ACPI hotplug enabled

[Igor Mammedov]

Since QEMU-6.1, Q35 machine is using ACPI PCI hotplug by default.
However SeaBIOS did not take in account pcie-pci-bridge and treated it
as any other PCIe device which is not correct in the case of the bridge.

Patch [1/2] fixes main issue by treating the bridge as a device with
possible SHPC capability.
Patch [2/2] fixes missed IO reservation, by making sure that in the case of
the bridge firmware reserves IO resource.

Igor Mammedov (2):
  pci: reserve resources for pcie-pci-bridge to fix regressed hotplug on
    q35
  pci: let firmware reserve IO for pcie-pci-bridge
