Okay, I suppose the IO mapping is guaranteed to work, ie. io_p2v() is behaving
correctly when xip_irqpending() is used, right ? I'm not challenging this, I'm
just ensuring this _could_ work (if anybody had the silly idea to make it work
again, and I admit I don't have that much courage).

This is not strictly equivalent to (ICIP & ICMR), I would have put for priority
reasons :
+#define xip_irqpending() (readl(ICIP) & readl(ICMR))
..zip..
Cheers.
