Thanks for the pointer. AFAIW the sun2 and sun3 targets aren't
SPARC-based.  However, SPARCstation is SPARC V7 (so not too different
from the sparc RTEMS), and the sun-4u is SPARC V9, for which I'll be
releasing an RTEMS port in 4.11 -- So I will check this out and see if
it might be useful as a testing tool.
