The Raspberry Pi Pico 2 is Raspberry Pi's first board fitted with their
RP2350A SoC.
This adds a minimal board definition, sufficient to build and run
`samples/hello_world` and `samples/basic/blinky` on the board. Images
can be run on the target using OpenOCD. Raspberry Pi's `picotool` can
create a UF2 binary, which ensures that errata RP2350-E10 is avoided
e.g.
```
> picotool uf2 convert build\rpi_pico2\hello_world\zephyr\zephyr.elf \
build\rpi_pico2\hello_world\zephyr\zephyr.uf2 \
--family rp2350-arm-s --abs-block`
```
Raspberry Pi Pico 2 is a low-cost, high-performance microcontroller
board with flexible digital interfaces. Key features include:
- RP2350A microcontroller chip designed by Raspberry Pi in the United
Kingdom
- Dual Cortex-M33 or Hazard3 processors at up to 150MHz
- 520KB of SRAM, and 4MB of on-board flash memory
- USB 1.1 with device and host support
- Low-power sleep and dormant modes
- Drag-and-drop programming using mass storage over USB
- 26x multi-function GPIO pins including 3 that can be used for ADC
- 2x SPI, 2x I2C, 2x UART, 3x 12-bit 500ksps Analogue to Digital
Converter (ADC), 24x controllable PWM channels
- 2x Timer with 4 alarms, 1x AON Timer
- Temperature sensor
- 3x Programmable IO (PIO) blocks, 12 state machines total for custom
peripheral support
- Flexible, user-programmable high-speed IO
- Can emulate interfaces such as SD Card and VGA
The Raspberry Pi Pico 2 comes as a castellated module which allows
soldering direct to carrier boards.
Only enable timer 0 for now. Timer 1 won't work correctly until the
rpi_pico HAL has picked up the fix for `hardware_alarm_irq_handler`. See
https://github.com/raspberrypi/pico-sdk/pull/1949 .
Added some documentation for the board itself (mostly aiming to refer to
canonical sources of information rather duplicate). Add entries in the
release notes where applicable.
