Since all SCMI transports have been made standalone drivers, remove all the
core SCMI stack legacy support that was needed to run transports as built
into the stack.

firmware: arm_scmi: Add support for standalone transport drivers2024-08-13T11:15:12+00:00Cristian Marussicristian.marussi@arm.com2024-08-12T17:33:35+00:00urn:sha1:8b76a8c95930a36389e2301b306747ff6f06cb16
Extend the core SCMI stack with structures and methods to allow for
transports to be split out as standalone drivers, while still supporting
old style transports, defined as built into the SCMI core stack.
No functional change.

firmware: arm_scmi: Introduce packet handling helpers2024-08-13T11:15:12+00:00Cristian Marussicristian.marussi@arm.com2024-08-12T17:33:34+00:00urn:sha1:b6b7c77c988a1314b2a3505f9962a6bfc563a8dc
Introduce a pair of structures initialized to contain all the existing
packet handling helpers, both for transports based on shared memory
and messages.
No functional change.

firmware: arm_scmi: Add message passing abstractions for transports2021-08-05T09:23:23+00:00Peter Hilberpeter.hilber@opensynergy.com2021-08-03T13:10:20+00:00urn:sha1:f301bba0ca7392d16a6ea4f1d264a91f1fadea1a
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.
