Madhukar Pappireddy cc485e27ac Rework smc_unknown return code path in smc_handler ... The intention of this patch is to leverage the existing el3_exit() return routine for smc_unknown return path rather than a custom set of instructions. In order to leverage el3_exit(), the necessary counteraction (i.e., saving the system registers apart from GP registers) must be performed. Hence a series of instructions which save system registers( like SPSR_EL3, SCR_EL3 etc) to stack are moved to the top of group of instructions which essentially decode the OEN from the smc function identifier and obtain the specific service handler in rt_svc_descs_array. This ensures that the control flow for both known and unknown smc calls will be similar.
