This file holds the UEFI build and evaluate instructions for RiscV Virt machine including a S-Mode EDK2 firmware and a StandaloneMm firmware which can be taken as a payload of the OpenSBI and run in a domain isolated by using the PMP/sPMP (re-used some Penglai code and put to OpenSBI).
We added MM service group in the RPMI spec Widget Connector
