SPARC64-V support

As of yesterday, OpenBSD/sparc64 has full support for Fujitsu's
SPARC64-V processor.  As far as I know OpenBSD is the first free
operating system that supports this processor.

These processors are found in Fujitsu's PRIMEPOWER machines.  The work
was done on a PRIMEPOWER 250, so that model is known to work.  This
almost certainly means the PRIMEPOWER 450 works fine too.  And there
is no real reason why other models shouldn't work too.  So if you have
one of these machines, it would be great if you could try booting
OpenBSD and send a dmesg.  Make sure you grab a snapshot dated May 23
or later.

Even if you have no opportunity to boot OpenBSD on your PRIMEPOWER
there still is a way to help.  I'm looking for the output of the
'prtconf -pv' command for these machines.  I'd also love to receive
that information for the SPARC Enterprise M4000/M5000/M8000/M9000 as
well as any older Fujitsu SPARC64-based machines.

Thanks,

Mark
