It doesn't make sense if you move 86xx under 85xx right now, no.

What I meant (but didn't write) was more along the lines of forking off
a new platform (I don't know if you have a common code name for the SoC
side, but fsl-whatever) that contains the SoC and board support for the
parts and boards that share much (looks like the latest gen 85xx and
8641 would be candidates).

Looks like the CPM2-based stuff could be candidates for something similar
as well, but there's less activity there so there's less reason to rework
those, I suppose.

Of course, down the road I'm sure there'll be a part that contains 75%
of the current SoC, plus something new. And the next gen after that only
contains the 25% non-shared plus 75% brand new stuff and it all falls
apart. Not knowing your roadmap I have a hard time judging if that's
likely though. :-)
