That's the third interrupt entry code handled here with ifdefs. I
remember there was some infrastructure to have multiple irq
controllers. I can't find any pointers, but I think Eric (added him
to Cc) told me about it.
As this is also the last roadblock to compile i.MX3 and i.MX5 into a
single kernel this might be the right moment to work on this.
