      stm32mp1: SCMI clock and reset service in SP_MIN · fdaaaeb4
      Etienne Carriere authored
      
      
      This change implements platform services for stm32mp1 to expose clock
      and reset controllers over SCMI clock and reset domain protocols
      in sp_min firmware.
      
      Requests execution use a fastcall SMC context using a SiP function ID.
      The setup allows the create SCMI channels by assigning a specific
      SiP SMC function ID for each channel/agent identifier defined. In this
      change, stm32mp1 exposes a single channel and hence expects single
      agent at a time.
      
      The input payload in copied in secure memory before the message
      in passed through the SCMI server drivers. BL32/sp_min is invoked
      for a single SCMI message processing and always returns with a
      synchronous response message passed back to the caller agent.
      
      This change fixes and updates STM32_COMMON_SIP_NUM_CALLS that was
      previously wrongly set 4 whereas only 1 SiP SMC function ID was to
      be counted. STM32_COMMON_SIP_NUM_CALLS is now set to 3 since the
      2 added SiP SMC function IDs for SCMI services.
