The SCMI is intended to allow OSPM to manage various functions that are provided by the hardware platform it is running on, including power and performance functions. SCMI provides two levels of abstraction, protocols and transports. Protocols define individual groups of system control and management messages. A protocol specification describes the messages that it supports. Transports describe the method by which protocol messages are communicated between agents and the platform. This patch adds basic infrastructure to manage the message allocation, initialisation, packing/unpacking and shared memory management.
