+ *                 authenticated data write requests made by the host.
+ * @addr         : Address of the data to be programmed to or read

+ * @result       : Includes information about the status of the write counter
+ *                 (valid, expired) and result of the access made to the RPMB.
+ * @req_resp     : Defines the type of request and response to/from the memory.
