Hi Liming,

thanks for your review!
Oh, I missed this, yes indeed, I can just include LockBoxNullLib and it works on RISCV64, too.
So we can drop this patch, too.

Cheers,
Daniel

Subject: RE: [edk2-devel] [PATCH v2 1/3] MdeModulePkg: Restrict libraries using SMM to x86

Daniel:
  Those modules consumes LockBox for S3 boot path. If the different ARCH doesn't depend on LockBox for S3 boot, it can use LockBoxNullLib.inf library instance. For EBC arch, LockBoxNullLib.inf has been specified. You can append more ARCHs with LockBoxNullLib library instance.

[LibraryClasses.EBC]
  LockBoxLib|MdeModulePkg/Library/LockBoxNullLib/LockBoxNullLib.inf

Thanks
Liming
