That's easy - the cooling maps are an entirely separate patch.
However, one thing we need to be careful of is whether someone has a
PWM fan plugged in, and whether not having any cooling maps results
in the fan stopping, as I think PWMs default to being disabled on
initialisation.

That could be a SoC-killing combination.
