 * Protocol overview
 *
 * request:  CMD [ P0 P1 P2 ... Pn S ]
 * response: ERR [ P0 P1 P2 ... Pn S ]
 *
 * where the bytes are defined as follow :
 *      - CMD is the command code. (defined by EC_CMD_ constants)
 *      - ERR is the error code. (defined by EC_RES_ constants)
 *      - Px is the optional payload.
 *        it is not sent if the error code is not success.
 *        (defined by ec_params_ and ec_response_ structures)
 *      - S is the checksum which is the sum of all payload bytes.
 *
 * On LPC, CMD and ERR are sent/received at EC_LPC_ADDR_KERNEL|USER_CMD
 * and the payloads are sent/received at EC_LPC_ADDR_KERNEL|USER_PARAM.
 * On I2C, all bytes are sent serially in the same message.
