The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.

I did an extremely quick pass. Fantastic!

  • I did update the esp32s2 build cache key, but the esp32s2 builds are failing due to a newly guarded include in supervisor/shared/safe_mode.c. I would try to fix it but I can't push to your PR's.
  • Trivial copyediting. Not important.
  • Calling the port raspberrypi might be confusing given one of your aspirations. 😃 Did you think about rp2 or similar?

* Calling the port `raspberrypi` might be confusing given one of your aspirations. smiley  Did you think about `rp2` or similar?

I know it might be confusing. MicroPython is rp2 so we can't use it. My thought is that this is the chip manufacturer. For raspberry pi boards we'll add ports/broadcom.

Fine by me! Could be rpi or rp2x but raspberrypi fine as well. I will just type [tab] 😄 .
