*Multi-level interrupt support*

Type: ``bool``

.. code-block:: none

    Multiple levels of interrupts are normally used to increase the
    number of addressable interrupts in a system. For example, if two
    levels are used, a second level interrupt aggregator would combine
    all interrupts routed to it into one IRQ line in the first level
    interrupt controller. If three levels are used, a third level
    aggregator combines its input interrupts into one IRQ line at the
    second level. The number of interrupt levels is usually determined
    by the hardware. (The term "aggregator" here means "interrupt
    controller".)
