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.

Heyi,
I have given the Reviewed-by for the whole patch series. So please just 
add my R-b if you want to send further version of patches.
I only have a minor comment for #4 patch. I don't think you need to send 
another version of #4 patch. You can just change the code when committing.
Thanks,
Ray

Thanks, but I don't have commit privilege myself, so maybe a v7 is needed, and I
will add your R-b for the whole series :)
