a variant that is very close to what you need. So most of the porting effort 
is already done. What you have to do hardly depends on the platform you have 
and the drivers you need.
What kind of evaluation board do you have ?

You have to decide on your own (or ask ecoscentric if they have a commercial 
port ready to use for you). I would be glad to see another fr30 architecture, 
with powerpc you have an architecture port that is more established and
