LEON3 interrupt controller
CONFIG_IRQ3_ENABLE
  Say Y here to enable the LEON3 interrupt controller. This is needed
  if you want to be able to receive interrupts. Operating systems like
  Linux, RTEMS and eCos needs this option to be enabled. If you intend
  to use the Bare-C run-time and not use interrupts, you could disable
  the interrupt controller and save about 500 gates.

LEON3 interrupt controller broadcast
CONFIG_IRQ3_BROADCAST_ENABLE
  If enabled the broadcast register is used to determine which
  interrupt should be sent to all cpus instead of just the first
  one that consumes it.
