2021-08-05firmware: arm_scmi: Add message passing abstractions for transportsPeter Hilber1-0/+111
Add abstractions for future transports using message passing, such as virtio. Derive the abstractions from the shared memory abstractions. Abstract the transport SDU through the opaque struct scmi_msg_payld. Also enable the transport to determine all other required information about the transport SDU.
