Sparc update

[Blue Swirl]

There was a bug in obp_nextprop, zs devices need to be mapped, and ESP 
needed an interrupt.

Now we get this far:

With NetBSD-GENERIC (forgot which version) we get this:
Jumping to entry point...

halt, power off

and with OpenBSD-3.5:
Jumping to entry point...
[ bsd ELF symbol table not valid: bad magic ]
data fault: pc=0xf8059a4c sfva=0xf05ea270 sfsr=126<FAV>

I think the error with Linux happens because the console device is not real 
serial but builtin console.

It used ascii "stan" as an address.  Does that help you?

This is probably due to:

romvec0.pv_romvers = 0;

can you run a trace at that point?

Yes, it is definitely dying in the serial driver code in linux.
