 * ============ KeyStore driver Secure Message Structs =========

 * KeyStore secure service. There is a single input vector for the PSA call
 * which is a pointer to secure message struct. If the underlying function
 * has a return value, there is a single output vector which is a pointer to
 * storage for the return value.
