The impact is mainly on the MCU hold boot management. 1) Configuration without SCMI server (legacy): Trusted context not activated - The MCU reset is controlled through the Linux RCC reset driver. - The MCU HOLD BOOT is controlled through The RCC sysconf. 2) Configuration with SCMI server: Trusted context activated - The MCU reset is controlled through the SCMI reset service. - The MCU HOLD BOOT is no more controlled through a SMC call service but through the SCMI reset service. In consequence this series: - Use the SCMI server to manage the MCU hold boot instead of the a SMC call service, - determine the configuration to use depending on the presence of the "reset-names" property if ( "reset-names" property contains "hold_boot") then use reset_control services else use regmap access based on "st,syscfg-holdboot" property. - Update the bindings and DTs in consequence.
