[edk2-devel] [edk2-staging][PATCH v1 2/7] MdePkg: MmCommunication: Add TPM subclass definition to MdePkg

[Kun Qin]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3966

This change introduces a new peripheral subclass definition.

The new subclass definition will cover system reboot events under the
status reports from Trusted Platform Modules (TPMs).

These definition could provide helpful datapoints to OEMs to analyze
system security state and healthiness, as well as avoid definition
collision with other existing peripheral subclass definitions.
