The purpose of this series is to establish a common baseline that people
can use to work on top off. We expect the non-bootable state to be very
temporary, but for practical reasons I want to get this merged so we can
make quicker progress.

Tegra238 is a derivative of Tegra234, so there's even more similarities
than we typically have across generational gaps. Your recent comments
suggested that you'd like to see new compatible strings no matter how
minimal (or even non-existent) the differences might be, so I suppose we
could prepend a Tegra238-specific compatible to this.
