This patch series allows users to access SCMI base protocol provided by SCMI server (platform). It will also be utilized in separate patches in the future to add sanity/validity checks for other protocols. See SCMI specification document v3.2 beta[1] for more details about SCMI base protocol.
What is currently not implemented is - SCMI_BASE_NOTIFY_ERRORS command and notification callback mechanism
This feature won't be very useful in the current U-Boot environment.
