The TEE subsystem allows session-based access to trusted services, requiring a session to be established to receive a service. This is not suitable for an environment that represents services as objects. An object supports various operations that a client can invoke, potentially generating a result or a new object that can be invoked independently of the original object. Add TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_INPUT/OUTPUT/INOUT to represent an object. Objects may reside in either TEE or userspace. To invoke an object in TEE, introduce a new ioctl. Use the existing SUPPL_RECV and SUPPL_SEND to invoke an object in userspace.
