For the ip2k silicon exists and has been in production since 2001 and is 
still very much in production.  It is supported by gdb although I need 
to check with our gdb maintainer what the status of merging that back to 
the FSF tree is.  There is a free simulator, ip2k-sim (it's what we use 
to regression test gcc).

FWIW there was no scheduler description becaust there is nothing 
interesting to describe.  If someone has a dummy scheduler description 
that does precisely nothing and they'd prefer this port to use then I'd 
be more than happy to generate the patches :-)
