I just got started with the openvehicles.com OVMS v3.1 module (which 
uses an ESP32) and I needed the xtensa-esp32-elf toolchain so I could 
move development from ubuntu to FreeBSD. I have done a few ESP8266 
projects with Arduino on ubuntu but the module doesn't have very many 
pio pins to start with and its internal flash uses a lot them so 
eventually I started working with the ESP32. (I have a project that can 
do wifi and wired ethernet with the waveshare lan8720 module, drive two 
spi oled displays and still have 5 pio pins for buttons.)

I've wanted to rename devel/arduino as arduino10, make a new 
devel/arduino that just provides a /usr/local/bin/arduino symlink to one 
of the two versions and then maybe add flavors for the library ports 
(e.g. arduino-irremote). And add ESP32 support to arduino18. I can 
probably help getting a xtensa-lx106-elf port going. (Looks like it also 
uses crosstools-NG so xtensa-esp32-elf is probably an excellent starting 
point).

The three of us should discuss offline.
