 * @brief Populated vector table in ROM
 *
 * Vector table at the beginning of the image for starting system. The reset
 * vector is the system entry point, ie. the first instruction executed.
 *
 * The table is populated with all the system exception handlers. The NMI vector
 * must be populated with a valid handler since it can happen at any time. The
 * rest should not be triggered until the kernel is ready to handle them.
