sun4u interrupt-map

[Artyom Tarasenko]

Could it be that OpenBIOS is missing interrupt-map and
interrupt-map-mask properties for the PCI bus?

On a real Ultra-5 it looks like this:
interrupt-map            0000003c 00000000 00000000 f005fa24 80000033
interrupt-map-mask       0000003e 00000000 00000000

What is mapped to what?

I couldn't find any documentation how these properties work, except
for Linux and OpenSolaris sources. Thought I ask here before trying to
reconstruct the picture from them.
