I haven't heared that anyone run NetBSD on DESKstation Tyne, yet.

Yes, I believe so.

Yes, I think so, too.

As far as I've heard, there is no CPU-visible cache on Tyne.

According to recent trouble of Prasad Nuli and Mark Abene,
changing CONSOLEIN and CONSOLEOUT variable on ARC box seems to
be quite dangerous... (Could Prasad recover his box?)

Also, currently serial console is disabled on NetBSD/arc for 
Tyne. (See "case DESKSTATION_TYNE: .... com_console_address = 0;"
of sys/arch/arc/arc/machedep.c), but, I believe you can safely change
this to
	com_console_address = TYNE_V_ISA_IO + 0x3f8;
or something like that.

I tried to keep Tyne suppport from OpenBSD on NetBSD/arc.
So, it should not be too hard.
But, since I don't have access to actuall hardware, probably
I made some mistakes...

Anyway, please mail me output of arcdiag of the Tyne box,
I really would like to see it.
(Also, please mail me arcdiag output of your Olivetti box,
 the output last you sent was incomplete... only first 16K bytes
 remained.)
Probably I should put arcdiag output archive on somewhere.
