Isn't this a little bit too simple? Not every ARM/ARM64 platform is a
heterogeneous one.

Does it matter?  Is there any problem with doing the callibration and
having it say that all the CPUs performs very similarly?  My
understanding was that this was simply saying it was worth checking to
see if there was some asymmetry.

No, the calibration would work on any platform. I can see your point,
you want to have this feature not depend on dt.
