Hello,

This patch has been tested on Arm-based systems.

* It was tested on our internal simulator based on QEMU which supports boost.
* It was tested on the Nvidia grace system (which does not support boost).
* The cppc_cpufreq driver is working on both of the above systems.

We have also confirmed that it continues to work as expected on AMD systems.

Regards.
