Subject: [PATCH v6 26/42] OvmfPkg: Add support to perform SEV-ES initialization
Date: Tue, 24 Mar 2020 12:40:40 -0500	[thread overview]
Message-ID: <704c01ad1d3dc778963695257518c2be60b7724e.1585071656.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1585071656.git.thomas.lendacky@amd.com>

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198

When SEV-ES is enabled, then SEV is also enabled. Add support to the SEV
initialization function to also check for SEV-ES being enabled, and if
enabled, set the SEV-ES enabled PCD (PcdSevEsIsEnabled).
