Subject: [PATCH v2 1/1] OvmfPkg/PlatformPei: drop S3Verification()
Date: Wed, 24 May 2023 11:11:17 +0200	[thread overview]
Message-ID: <20230524091117.302120-1-kraxel@redhat.com> (raw)

Not needed any more, SMM + 64-bit PEI + S3 suspend works now.  While
being at it also remove it from Bhyve (where it is dead code).

Fixed by commits:
 - 8bd2028f9ac3 ("MdeModulePkg: Supporting S3 in 64bit PEI")
 - 6acf72901a2e ("UefiCpuPkg: Supporting S3 in 64bit PEI")
