AFAIK, no pci-host device abstraction exists.
Each arch deals with pci-host bridges as it sees fit.

But access methods to some PCI features are abstracted:
o method access to CFG space
o method to register IRQs
o advertise MMIO/IO Port routing.

Sounds like you want to add another method for error recovery
stats/control.
