Looking at the list above, I don't see an update to SUPPORT.md. So I
believe, this would fall under:
### Arm: SCMI over SMC calls forwarding to EL3 Firmware
Enable SCMI calls using SMC as doorbell mechanism and Shared Memory for
transport ("arm,scmi-smc" compatible only) to reach EL3 Firmware if issued
by hwdom. Some platforms use SCMI for access to system-level resources.
Status: Supported
I think this should be updated for the multi-agent support to tech preview.
Cheers,
