 * @brief Tests the leon3 BSP family SMP-specific shutdown procedure.
 *
 * This test case performs the following actions:
 *
 * - Check the effects of the leon3 BSP family shutdown procedure.
 *
 *   - Check that the second processor was not powered down during system
 *     initialization.
 *
 *   - Wait until the second processor is powered down.
 *
 *   - Check that the RTEMS_FATAL_SOURCE_SMP with SMP_FATAL_SHUTDOWN_RESPONSE
 *     fatal error occurred exactly once.
 *
 *   - Check that the RTEMS_FATAL_SOURCE_SMP with SMP_FATAL_SHUTDOWN_RESPONSE
 *     fatal error occurred on the second processor.
