Raspberry Pi Pico W

I am looking into adding support for the Raspberry Pi Pico W which uses the Infineon’s CYW43439 WiFi chip.

Rather than trying to write I complete interface to this chip, I was wondering whether it would be appropriate to build with the code in the Pico-SDK supplied by the Raspberry Pi foundation.  

The library Pico-SDK uses to communicate with the  CYW43439 is Copyright George Robotics Pty Ltd, and is generally licensed for non-commercial purposes.  It is also licensed for use with the RP2040 (or other Raspberry Pi Foundation chips) in a manner that permits commercial use.

Any thoughts on this would be appreciated.

Pulling in that SDK upstream is likely not feasible for multiple reasons
including the licencing side. That said there already is some support for
the BCM43xxx chips which if I recall correctly are the same family, and it
may be not too much work to add missing support.
