   * The FreeRTOS Cortex-A port implements a full interrupt nesting model.
   *
   * Interrupts that are assigned a priority at or below
   * configMAX_API_CALL_INTERRUPT_PRIORITY (which counter-intuitively in the ARM
   * generic interrupt controller [GIC] means a priority that has a numerical
   * value above configMAX_API_CALL_INTERRUPT_PRIORITY) can call interrupt safe
   * FreeRTOS API functions and will nest.
   *
   * Interrupts that are assigned a priority above
   * configMAX_API_CALL_INTERRUPT_PRIORITY (which in the GIC means a numerical
   * value below configMAX_API_CALL_INTERRUPT_PRIORITY) cannot call any FreeRTOS
   * API functions, will nest, and will not be masked by FreeRTOS critical
   * sections (although it is necessary for interrupts to be globally disabled
   * extremely briefly as the interrupt mask is updated in the GIC).
   *
   * FreeRTOS functions that can be called from an interrupt are those that end in
   * "FromISR".  FreeRTOS maintains a separate interrupt safe API to enable
   * interrupt entry to be shorter, faster, simpler and smaller.
   *
   * The Cyclone V SoC implements 32 unique interrupt priorities.  For the
   * purpose of setting configMAX_API_CALL_INTERRUPT_PRIORITY 32 represents the
   * lowest priority.
