Subject: [PATCH v3 5/5] OvmfPkg/Tcg2ConfigPei: Update Depex for IA32 and X64
Date: Thu, 29 Apr 2021 12:12:14 -0500	[thread overview]
Message-ID: <d6538e6c557173d260e272a0e5659683175e2e06.1619716333.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1619716333.git.thomas.lendacky@amd.com>

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3345

The OVMF Tcg2Config PEIM adds the gOvmfTpmMmioAccessiblePpiGuid as a
Depex for IA32 and X64 builds so that the MMIO range is properly mapped
as unencrypted for an SEV-ES guest before the Tcg2Config PEIM is loaded.
