Subject: [PATCH v4 5/5] OvmfPkg: rework TPM configuration
Date: Wed, 15 Dec 2021 12:39:20 +0100 [thread overview]
Message-ID: <20211215113920.1015403-6-kraxel@redhat.com> (raw)
In-Reply-To: <20211215113920.1015403-1-kraxel@redhat.com>
Rename TPM_ENABLE to TPM2_ENABLE so naming is in line with the
ArmVirtPkg config option name.
Add separate TPM1_ENABLE option for TPM 1.2 support.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
Tested-by: Stefan Berger <stefanb@linux.ibm.com>
