Thanks Gerd, I will try the S3 on OVMF.

And for AmdSmmRelocationLib usage in OVMF, do you prefer:
1. use the AmdSmmRelocationLib directly in this patch set? Or
2. still keep the original to create the OvmfPkg/SmmRelocationLib, and clean 
the code in the future patch?

Both are fine to me, depends on you.

Thanks,
Jiaxin
