Foreword
========
-Two implementations of a Secure Partition Manager co-exist in the TF-A codebase:
-
-- SPM based on the FF-A specification (:ref:`Secure Partition Manager`).
-- SPM based on the MM interface.
-
-Both implementations differ in their architectures and only one can be selected
-at build time.
-
-This document describes the latter implementation where the Secure Partition Manager
-resides at EL3 and management services run from isolated Secure Partitions at S-EL0.
-The communication protocol is established through the Management Mode (MM) interface.
