Can you help to fix the build failure for these platforms in https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ftianocore%2Fedk2-platforms&data=02%7C01%7Cthomas.lendacky%40amd.com%7C9cff3475aff84a95728508d7f1604c99%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637243268217382019&sdata=jU0qrB%2BV6ZvFmPzjcxGo9o2Pu1%2FrhRW0gUZTMv%2BiXDQ%3D&reserved=0

I have fixed all of the build issues associated with the VS compiler using 
the pull request method that Laszlo mentioned. I then successfully built 
the RPi4 platform under GCC (build -n 32 -a AARCH64 -t GCC5 -p 
Platform/RaspberryPi/RPi4/RPi4.dsc) using the AARCH64 cross compiler.

Is there a particular platform that experiences an issue or are the 
failures related to the VS compiler errors that my next series will have 
fixed?

I don't see any platform other than OVMF using this feature as it is a 
virtualization feature. Having said that I can add an explanation of what 
is needed should another virtualization platform be created under EDK2 
that wants to support SEV-ES. And, as you said, I can also explain the 
feature overall on the page.

Thanks. Is there anyone in particular that I need to request this feature 
be added?

Thanks,
Tom
