Yes. This way does work. We will update the patch for it.

Thanks for the explanation.
Yes, I agree we need resolve the build issue.

I do not suggest to remove the API in SecFspSecPlatformLibNull, because we need provide a good sample to real FSP implementation.

Can we add empty symbol in FspApiEntryM.nasm and FspApiEntryS.nasm?

Thank you
Yao Jiewen

Jiewen:
  The change is in SecFspSecPlatformLibNull. This library instance provides the dummy function. It should not be used by any real FSP. We meet with the build issue with /WHOLEARCHIVE option. Because this library depends on the external TempRamInitApi(), but FspSecCoreS and FspSecCoreT don't provide TempRamInitApi(). Then, FspSecCoreS and FspSecCoreT will build failure. To fix this build failure, we choose to remove this unnecessary dependency.
