Great!

Is this option to keep imx6[q,qp,dl,solo]sabresd.conf configs and add a
new one that is something like imx6-spl-sabresd.conf?

I think option #2 sounds cleaner and it's more beneficial to people doing
their own spl-based designs since it's easier to find and follow. It also
would make using SPL the default for a lot of new designs which is
probably a good thing.

Also who knows, it might nudge NXP to merge their stuff and use SPL too.
