Add initial RP2040 support 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. Datasheet: https://pico.raspberrypi.org/files/rp2040_datasheet.pdf 2021-01-20 19:47:18 -05:00			`USB_VID = 0x239A`

Redo RP2040 flash settings This switches stage2 to C and uses Jinja to change the C code based on flash settings from https://github.com/adafruit/nvm.toml. It produces the fastest settings for the given set of external flashes. Flash size is no longer hard coded so switching flashes with similar capabilities but different sizes should just work. This PR also places "ITCM" code in RAM to save the XIP cache for code execution. Further optimization is possible. A blink code.py still requires a number of flash fetches every blink.
