Yes, it is still used by the xinput_calibrator binary. 

If there is a  pointercal file (/etc/pointercal.xinput) defined for the device,
xinput_calibrator use it. Otherwise, the startup script runs the calibrator
and save the ‘xinput’ commands printed on stdout in the pointercal file.

Have tried a core-image-sato build with meta-fsl-arm for imx28evk to locate the
obvious failures. Build was successful.

Are you using this specific touch screen in your device? 

Most probably, we should fix the pointercal.xinput file in meta-fsl-arm for the
latest xinput_calibrator, for your machine. Please do file a bug.
