*Multi-level interrupt support*

Type: ``bool``

Help
====

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".)
