I didn't say it wasn't well defined ;) I said it's usage by Apple is not.

prom.c has an interrupt tree parser that is used only on newworld macs
(they have a valid interrupt tree) and only when booting via Open
Firmware (booting via MacOS kills too much infos from the device tree to
be able to parse the interrupt tree any more).

I think it's also used on CHRP.
