 * In Case 1/2, Mbed OS takes over vector table.
 * In Case 3, TFM takes over vector table.
 *
 * If TFM_LVL isn't defined, it is equivalent to TFM_LVL == 0.
 *
 * FIXME: Currently, we still go mbed relocating vector table sequence. When TFM (Secure PSA)
 *        updates to take over NVIC itself, we must disable this sequence:
 *        1. Do not allocate vector RAM (cmsis.h/cmsis_nvic.h/linker files):
 *           Image$$ER_IRAMVEC$$ZI$$Base
 *           __section_begin("IRAMVEC")
 *           __start_vector_table__
 *        2. Secure PSA may go mbed boot sequence. We must leave NVIC_RAM_VECTOR_ADDRESS
 *           undefined to make the mbed_copy_nvic() function dummy (cmsis_nvic.h).
