[edk2-devel] [PATCH v6 20/29] OvmfPkg/PlatformPei: set the SEV-SNP enabled PCD

[Brijesh Singh via groups.io]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275

The MpInitLib uses the PcdSevSnpIsEnabled to determine whether the SEV-SNP
is active. If the SEV-SNP is active, then set the PCD to TRUE.
