 The EETI touchscreen needs calibration after assembly, otherwise there may
 be dead zones or other mis-tracking.

 It would be good to do it during factory test.

 That said, I wonder if the calibration might drift before the unit is
 deployed, maybe as a result of temperature, altitude, humidity, shipping
 conditions, or other factors.  So it might be a good idea to recalibrate
 it somewhere else too, perhaps just before booting, or somewhere in the
 Linux startup.
