Subject: [PATCH V5 09/13] OvmfPkg/PeilessStartupLib: Delete the duplicated tdx measurement
Date: Sat, 28 Jan 2023 21:58:38 +0800 [thread overview]
Message-ID: <20230128135842.980-10-min.m.xu@intel.com> (raw)
In-Reply-To: <20230128135842.980-1-min.m.xu@intel.com>
From: Min M Xu <min.m.xu@intel.com>
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243
After TdHob and Configuration FV (Cfv) are measured in SecMain, the
same measurements in PeilessStartupLib should be deleted.
