[edk2-devel] Regarding StandaloneMmPkg/Include/Guid/MpInformation.h

All,

StandaloneMmPkg/Include/Guid/MpInformation.h contains the MP_INFORMATION_HOB_DATA HOB definition.
This HOB is used for transfering MP information collected in non-SMM phase to standalone MM environment.

#pragma pack(1)
typedef struct {
  UINT64                       NumberOfProcessors;
  UINT64                       NumberOfEnabledProcessors;
  EFI_PROCESSOR_INFORMATION    ProcessorInfoBuffer[];
} MP_INFORMATION_HOB_DATA;
#pragma pack()

extern EFI_GUID  gMpInformationHobGuid;


Is there any reason that the MP_INFORMATION_HOB_DATA HOB definition not documented in PI spec?
If no reason, I do feel that PI spec needs to carry the HOB definition.
Thoughts?

Thanks,
Ray
