Greetings Sadeep,

The ESP32 xtensa port is really just designed to work with the Arduino
environment, using the makeEspArduino port. There is way too much black
magick to get the esp-idf to run on OpenBSD, with all its Linuxisms,
which is why there is no esp-idf port.

I had a version running a few years back, but gave up on the effort
since it was too much trouble and wouldn't fit within ports as it was.

Thanks,
Tracey
