Thread-topic: Interrupt routing issue on BCM1480.
Hi guys,

Ralf's fixes in arch/mips/pci/pci-bcm1480.c break on our board. Multiple
devices somehow report the same pin number (or perhaps some invalid pin
number that is mapped to 1).  The mapping function then assigns IRQ 8 to
multiple devices.

The old ``return dev->irq'' in pcibios_map_irq worked fine.

What was the issue: is it that CFE sets up these IRQ numbers, such that
they might not correspond to pins?
