Hi,
I think these are the "functional" changes that need to be included in
the ibmebus driver. We'll add a RT flag in the final version to enable
these changes only for RT-Linux for now.
Ben, can you / your team look into the implementation
of the set_irq_type functionality needed for XICS?
Regards,
Jan-Bernd & Christoph
