[edk2-devel] [edk2-platforms: PATCH v3 1/6] MinPlatformPkg: Add SetCacheMtrrLib library class.

Thanks for updating the name.
Platform\Intel\MinPlatformPkg\Include\Library\SetCacheMtrrLib.h:
* The function description for SetCacheMtrrAfterEndOfPei () is
constraining the implementation in a way that I don't believe
is required:
/**
Update MTRR setting and set write back as default memory attribute.
@retval EFI_SUCCESS The function completes successfully.
@retval Others Some error occurs.
**/
While it is typical to set the default memory type to WB, I don't
think this API should care whether that is the case.
* "SetCacheMtrrAtEndOfPei ()" better describes the way this
is actually being used but I don't think it is a must change.
With the function description updated:
