That was my thought.  If it were important enough to keep in
*this* source base, someone would have submitted some board
that uses it.  It's badly enough broken that I don't know who
would bother using it, though; anyone trying to use it has some
kind of (non-Linux?) support nightmare already.

I wouldn't mind doing that.

Right, mainline does not use that "broken" ECC.  I can't
figure out who *does* use it, either...
