First, *PLEASE* don't start from 2.0 - it's nearly 5 years old
and very out of date.  Use CVS instead.

Secondly, read the porting guide, part of the standard documentation.
It has lots of good information about how to create new targets and
packages.

Finally, any changes you make for your port go in .CDL files.  The
.ECC files are ethereal (not part of the source tree and are recreated
*every* time you run 'ecosconfig')
