Must be an error in the preliminary spec. I have the engineering docs from 
AMCC and here UIC1 IRQ0 is the external IRQ 2, which is used for PCI. So this 
is still wrong in the current dts version. I'll send an updated version 
probably tomorrow.

Again, your documentation is incorrect. Took me 1/2 a day to figure this out 
myself.
