Re: [PATCH] UefiPayloadPkg: Fix the warning when building UefiPayloadPkg with IA32+X64

["duntan" <dun.tan@intel.com>]

Hi Ray,

There are only "UniversalPayloadEntry.inf" and "UefiPayloadEntry.inf" under [Components.IA32] in UefiPayloadPkg.dsc. The [Packages] sections in these two .inf file only contain MdePkg, MdeModulePkg, UefiCpuPkg and UefiPayloadPkg. So the PCDs in .dec files of these four pkgs used in UefiPayloadPkg.dsc will not be treated as unspecified PCDs when building with IA32. In order to avoid warnings when building under IA32, the PCDs in the dec files other than these four pkgs needs to be placed in the PCD section with the 'X64' suffix in UefiPayloadPkg.dsc.

The ' gEfiMdeModulePkgTokenSpaceGuid.PcdAriSupport' is in 'MdeModulePkg.dec '. So it won't be regarded as an unspecified PCD.

Thanks,
Dun

Dun,
I am curious, why ' gEfiMdeModulePkgTokenSpaceGuid.PcdAriSupport' doesn't cause build warning?
It is referenced by "MdeModulePkg/Bus/Pci/PciBusDxe/PciBusDxe.inf" under "[Components.X64]".

Thanks,
Ray
