While loading 7.1.0.9 release in ST60/SU60, driver indicates "/lib/firmware/lrdmwl/regpwr.db not found." What does it mean and how to handle it?

While loading 7.1.0.9 release in ST60/SU60, driver indicates "/lib/firmware/lrdmwl/regpwr.db not found." What does it mean and how to handle it?

It’s the adaptive world mode component (awm) which implements 802.11d/WorldMode “roaming” for SU60, not for ST60.
Among other things it includes a daemon which runs and checks the geo-location of the radio and sets the regulatory domain accordingly.  
The message is just informational. It is not an error and will not cause any problems.

To integrate this part, if you build by yocto, you can add adaptive_ww in your recipe.
