Thank you for your work, it would be great to get more OSes running on
Qemu/OpenBIOS.
Just one comment: On my Sun4m machine (SS-5) the OBP properties for
interrupt and counter reg nodes are as follows:
$ cat obio/interrupt\@0\,e00000/reg
00000000.00e00000.00000010.00000000.00e10000.00000010
$ cat obio/counter\@0\,d00000/reg
00000000.00d00000.00000010.00000000.00d10000.00000010
Your patch deviates from this. If you want to emulate a SS-10, it may be
better to add it as a new sub-machine type to Qemu and OpenBIOS. I don't
know how much SS-5 and SS-10 differ. For example, what is the MMU on SS-10,
is it also Swift (SRMMU)?
