+          Support for a CROSSBAR ip that preceeds the main interrupt controller.
+          The primary irqchip invokes the crossbar's callback which inturn allocates
+          a free irq and configures the IP. Thus the peripheral interrupts are
+          routed to one of the free irqchip interrupt lines.
