I want to hear what Priyanka has to say, as there's been an effort a
few times on NXP's part to remove boards they don't want to maintain
anymore.

Outside of that, I do keep meaning to, but not quite finding the time
to, pick a random well-past migration deadline, make it fatal, and then
go start removing boards.  I think I'll go pick a not-PCI (as some
number of PowerPC ones will fail, and that's not as interesting until
Priyanka can chime in) one right now and see what fails there.
