Code can also be found here:
https://github.com/iwishguo/edk2/tree/patch-pci-host-bridge-v7

v7:
- Patch 4: implement 1 comments from Ray.

v6:
- Patch 1, 2: implement 3 comments from Laszlo.
- Patch 4: implement 3 comments from Ray.

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.

Thanks Heyi.

I will merge this v7 by the end of today unless anyone objects.

Maurice, Prince, Benjamin: you have had ample time to respond to the
Coreboot changes. I am going to assume that you have no objections
unless you raise them today.

Thanks all,
Ard.

Hi,

I consulted Ray. I have no objection to the patch for CorebootPayloadPkg.

Thanks,

I see you added your R-b to the OvmfPkg commit (e33305ea6c6a), so
everything is OK from my side. (The patch is good as well.)

Thanks!
