Please note: this is still *RFC* version, so we have not gone thru all the code in EDK2 for applying the change of PciSegmentLib definition.
v4: - Modify the code according to the comments from Ray, Laszlo and Ard (Please see the notes of Patch 1/3) - Ignore translation of bus in CreateRootBridge. v3: - Keep definition of Translation consistent in EDKII code: Translation = device address - host address. - Patch 2/2 is split into 2 patches (2/3 and 3/3). - Refine comments and commit messages to make the code easier to understand. v2: Changs are made according to the discussion on the mailing list, including: - PciRootBridgeIo->Configuration should return CPU view address, as well as PciIo->GetBarAttributes, and Translation Offset should be equal to PCI view address - CPU view address. - Add translation offset to PCI_ROOT_BRIDGE_APERTURE structure definition. - PciHostBridge driver internally used Base Address is still based on PCI view address, and translation offset = CPU view - PCI view, which follows the definition in ACPI, and not the same as that in UEFI spec.
