Then, this is currently broken in all cases
and needs to be fixed since the CPM/CPM2
could have up to six UART ports.

Now I don't know anything about the Altix card, so I don't know if  
it's possible to use that card on a system with a CPM or a QE.  If  
it isn't, then I don't know if overlapping minor numbers is still a  
problem.

I don't think that would be a problem, and I'd like the
CPM/QE to share devices because it makes the
software distributions common to all Freescale
embedded processors.

If we move CPM/QE to 192, then I can change the CPM device driver  
to reflect that, but I don't know what that means for older kernels.

That would be bad.  It has nothing to do with the
kernel, but we have finally survived the distribution
updates to ttyCPM, and I don't want to go through
that again just because of QE.

Thanks.
