Adafruit Fruit Jam board

• Fixes Add Adafruit Fruit Jam board #2362.

Add Adafruit Fruit Jam "Mini RP2350 Computer" board. https://www.adafruit.com/product/6200. Description:

• RP2350B dual 150MHz Cortex M33
• PicoProbe debug port
• 16 MB Flash + 8 MB PSRAM - the PSRAM will help when we want do do things like run emulations that we need to store in fast RAM access, and also let us use the main SRAM as the DVI video buffer.
• USB type C for bootloading/USB client
• Micro SD card with SPI or SDIO
• DVI output on the HSTX port
• I2S stereo headphone + mono speaker via the TLV320DAC3100
• 2-port USB type A hub for both keyboard and mouse or game controllers
• Chunky on-off switch
• Stemma QT I2C
• Stemma classic JST 3-pin
• EYESPI for TFT displays
• 5x NeoPixels
• 3x tactile switches
• 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins.

LGTM 👍

Hmmm, for the benefit of users of your new board, is it worth adding additional defines to your header for "3x tactile switches" etc. ?

Yes, probably a good idea :) Done.

I see that https://www.adafruit.com/product/6200 currently says "we also need a name, right now we're just calling it Fruit Jam since its inspired by the IchigoJam project." - has the name now been finalised? Looks like a fun little board though 😃

I apologize for the churn here. It's been a bit of a moving target. Fruit Jam is going to be the name -- that copy hasn't been updated yet. There will also be a WiFi/BLE co-processor on the final board. We've got it running a bunch of emulators now, like C64, old Mac (HyperCard, anyone?) etc.

Note 2.1.2 is approaching - so best to finalize this soon

@lurch This is ready for re-review. The board is in its final form now. Changes here reflect your suggestions from #2510 (another PR for this board that you reviewed and then we closed in favor of this one). I ran https://github.com/raspberrypi/pico-sdk/blob/master/tools/check_board_header.py and it does not complain. Thank you.

One question: is #define PICO_BOOT_STAGE2_CHOOSE_W25Q080 1 correct if we are using a W25Q128 (16MB)?

Tagging @ladyada for reference.

I'm afraid I don't know the answer to that, but @will-v-pi or @kilograham might know?

Oh, I've also just remembered that there's a pico_audio library in pico-extras as well, so maybe you want to include some of the PICO_AUDIO_ defines from https://github.com/raspberrypi/pico-sdk/blob/develop/src/boards/include/boards/vgaboard.h too?
(of course this is all entirely optional, but I believe that these extra defines will make it easier to get some of the pico-playground demos running on your new board)

I added yet more pins for I2S.

I started writing something about the limitations and implicitness of passing of pins and settings via macro names versus function call arguments, but this PR was not the place to discuss it. You can see how the API's from pico-extras, etc., are leaking into the board header files. Maybe I'll bring it up in the forums or in a pico-extras issue.
