Argh... Can you foresee how much longer this hardware is likely to be
maintained?

Yes, this would be possible, too.  But then, it appears you are the
only remaining active user of MPC82xx.  OK, MPC8247 is actually still
marked as "active" at Freescale, soory I missed that - the MPC824x
types I checked were in "No Longer Manufactured" state.

The thing is that there are tons of interdependencies an #defines that
need to be checked so we don't leave too many unused #defines and such
around.

I see several options now:

1) We apply the patch as is, and if you really have to modify your
   code you would do this out-of-tree based on the last frozen
   version.

2) I rework the patch to remove only the MPC826x / MPC828x code.

3) I rework the patch to remove only the broken boards - which are
   these actually?


Tom, what is your opinion here?

Best regards,

Wolfgang Denk
