GCD consumes the protocol to issue a Notify() on Add/Remove operations.
The intended use-case is to allow OvmfPkg take actions on behalf of an
SEV-enabled guest.
The new protocol is simply added to the list of optional protocols handled
by DxeMain, and as such leverages the existing DxeProtocolNotify framework.
I will follow this patch with "proof-of-concept" OvmfPkg driver that
installs the protocol to take pertinent actions based on GCD notifications.
