emips status?

[Havard Eidnes <he%NetBSD.org@localhost>]

Hi,

I've toyed a bit with the giano emulator from Microsoft, mostly
to see if the emips port is in a runnable state.  Unfortunately,
it looks like the answer to that is "no" at the moment.

After my tvivial fix:

   Modified Files:
	   src/sys/arch/emips/emips: machdep.c

   Log Message:
   Initialize iospace_size instead of iospace (will be overwritten) to 64k.
   Brings boot of emips on giano a bit closer, but now it's stuck (hangs).

it gets a bit further, doesn't panic anymore, but also is not
<break>able into DDB, so as far as I can see it's wedged.  Hints
for next steps appreciated.  Dmesg so far attached below.

Regards,

- Håvard
