thanks for reporting this.

Marc: I completely forget about this wiring for very ancient platform.
AFAIK Xilinx is not testing this platform for years and would likely the
best to remove support for it completely.
The second option is to get xintc_get_irq() back with note about powerpc
because it won't be that simple change all PPC platform to generic
domain irq handler.
Any other suggestion?

Thanks,
Michal
