+ The cores on the AXI bus are automatically detected by bcma with the

++Automatic detection of the IRQ number is not working on
++BCM47xx/BCM53xx ARM SoCs. To assign IRQ numbers to the cores, provide
++them manually through device tree. Use an interrupt-map to specify the
++IRQ used by the devices on the bus. The first address is just an index,
