Take a look at src/sim/README-HACKING.  It has some bits and pieces on
the subject.  The main other things to watch for are:

* sim/configure.in - to map target triples to sim/<processor> subdirs
  Add a clause for your target.

* sim/<processor>/Makefile.in and configure.in - source tree build skeleton
  If you're using sim/common, copy these files from anther port such as d30v,
  mips, fr30.

* populate sim/<processor> and get things running.

* Send a pack of patches.  We can tidy up the build system here, if needed.


I believe we will need an FSF copyright assignment, so you may want to get
started on that paperwork in parallel.
