Patch v5 inherits the code from RFC v4; we don't restart the version number for RFC to PATCH change.
v5: - Patch 4/6: Modify the code according to the comments from Ray. - Patch 1/6 and 2/6 are totally new. They add initialization for all fields of PCI_ROOT_BRIDGE_APERTURE temporary variables in PciHostBridgeLib instances, so that they will not suffer from extension of PCI_ROOT_BRIDGE_APERTURE structure. - Generate a separate patch (3/6) for PciHostBridgeLib.h change. Though it is a prerequisite for patch 4/6, it does not change the code in PciHostBridge driver and won't cause any build failure or functional issue. 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.
