Save and use the 3rd parameter of PSCI CPU_ON request: context_id.The context_id parameter is only meaningful to the caller. U-Boot PSCI preserves a copy of the value passed in this parameter. Following wakeup from a powerdown state, U-BOOT PSCI places this value in R0 when it first enters the OS. NB: this context id is not (yet?) used by Linux but it is mandatory to be PSCI compliant. update armv7 psci functions: - psci_save_target_pc(): keep for backward compatibility with current platform (only save PC and force context id to 0) => should be removed when all platform migrate to the new API - psci_save(): new API to use by ARMv7 platform with PSCI, save pc (= entry_point_address) and context_id
