Add Mor feature
Issue Description:
When SUT boot to Windows 10 (10586), MRC will clear memory when SUT enter into S4, Shutdown, etc...
Root Cause:
BIOS Platform ASL code Method(_PTS,1) to call “SB.TPM.PTS” method, which include SMI handler code that clears Mor variable, so
If the SUT enter S4, S5(shutdown), Restart normally, the BIOS SMI handler code will clear Mor variable.
[Test]
Windows 10(10586) s3, s4, shutdown, restart, boot, install OS passed
Windows 8 s3,s4,boot passed.
Yotcot s3, boot passed.
