[edk2-devel] [PATCH v4 16/20] SecurityPkg: Tpm2DeviceLibDTpm: Introduce StandaloneMm instance
Kun Qin
kun.q at outlook.com
Tue Jan 26 19:47:06 UTC 2021
This change added a new instance of Tpm2DeviceLibDTpm to support drivers
of type MM_STANDALONE. It abstracts dynamic Pcd access into separate file
for different instances to avoid dynamic usage for StandaloneMm modules.
