| |
All the currently defined SCMI events are meant to trace only regular SCMI transfers based on SCMI messages exchanges; SCMI transactions based on FastChannels, where used, are completely invisible from the tracing point of view.
Add support to trace FastChannel transactions; while doing that avoid exposing full shared memory location addresses.
