37  * This file implement the SMC ABI used when communicating with secure world
41  * 2. Low level support functions to register shared memory in secure world
43  * 4. Do a normal scheduled call into secure world
266  * 2. Low level support functions to register shared memory in secure world
268  * Functions to enable/disable shared memory caching in secure world, that
285 	/* We need to retry until secure world isn't busy. */  in optee_enable_shm_cache()
310 	/* We need to retry until secure world isn't busy. */  in __optee_disable_shm_cache()
582  * when dynamic shared memory is supported by secure world.
640  * 4. Do a normal scheduled call into secure world
643  * call into secure world. During this call may normal world request help
644  * from normal world using RPCs, Remote Procedure Calls. This includes
804  * optee_handle_rpc() - handle RPC from secure world
844 		 * A foreign interrupt was raised while secure world was  in optee_handle_rpc()
875  * optee_smc_do_call_with_arg() - Do an SMC to OP-TEE in secure world
877  * @shm:	shared memory holding the message to pass to secure world
881  * Does and SMC to OP-TEE in secure world and handles eventual resulting
884  * Returns return code from secure world, 0 is OK
941 			 * Out of threads in secure world, wait for a thread  in optee_smc_do_call_with_arg()
960 	 * We're done with our thread in secure world, if there's any  in optee_smc_do_call_with_arg()
1148  * During driver initialization is secure world probed to find out which
1442 	 * reference counters and also avoid wild pointers in secure world  in optee_smc_remove()
