I dunno, if the firmware affects the functionality of the hardware in a
way that cannot be detected from the operating system at runtime how
else is it supposed to deal with that?
The devicetree is supposed to describe hardware, yes, but at a certain
point the line between firmware and hardware is invisible :)
Not describing software is mostly about not using it to determine
software policy in the operating system.
