[SeaBIOS] [RFC PATCH 0/2] Allow RedHat PCI bridges reserve more buses than necessary during init

[Aleksandr Bezzubikov]

Now PCI bridges (and PCIE root port too) get a bus range number in system init,
basing on currently plugged devices. That's why when one wants to hotplug another bridge,
it needs his child bus, which the parent is unable to provide.
The suggested workaround is to have vendor-specific capability in RedHat generic pcie-root-port
that contains number of additional bus to reserve on BIOS PCI init.

Aleksandr Bezzubikov (2):
  pci: add support for direct usage of bdf for capability lookup
  pci: enable RedHat pci bridges to reserve more buses
