The Generic Root Port behaves the same as the Intel's IOH device with id 3420, without having Intel specific attributes. The device has two purposes: (1) Can be used on both X86 and ARM machines. (2) It will allow us to tweak the behaviour (e.g add vendor-specific PCI capabilities) - something that obviously cannot be done on a known device. Patch 1/3: Introduce a base class for Root Ports - most of the code is migrated from IOH3420 implementation. Patch 2/3: Derives the IOH3420 from the new base class Patch 3/3: Introduces the generic Root Port. Tested with Linux and Windows guests only on x86 hosts.
