* Adds RISC-V compilation option to the IDE and Platform.IO.
* Build RP2350-RISCV libpico, libbearssl
* Fix RP2350 BearSSL library (was copied from RP2040, now built for M33)
* New GCC 14.2 toolchain is required (12.4 RISC-V support is borked)
* Newlib locking fixed prototypes
* Manually force all runtime init code into RP2350 binaries
* Add RISC-V to CI
* Remove RP2350 BOOT2.S files, binaries (not used)
* Clean up minor GCC 14.x warnings
* Add RP2350-RISCV OTA build, link
* Add RISC-V FreeRTOS files (configuration still not running, but builds)
* Add basic documentation
Newlib built using `-Os` causes things like `memcpy` to be very slow on the
RP2350 because it uses byte-wise operations. On the RP2040 this doesn't
matter because there is a ROM routine we use instead of the library, but on
the Pico 2 it's almost 10x slower than the optimal method.
Update GCC to 12.4
Update Newlib to 4.4.0
Move to -O2 library compilation
New toolchain looks to add ~10K to RP2350 flash usage (less on the RP2040).
* Adds a menu item for selecting type of ESP wifi type.
* Updated pin definitions to work with ESP hosted.
* Fixed residual debug modification.
* Added ESPHost support library.
* Removed local cloning of ESPHost and added to excluded from CI
* Updated boards.txt

Split the 1300+ char define-setting line into a multi-line value.
Makes it more maintainable and easier to see when changes needed.
No settings should have been modified.
The RP2350 has a different blob header requirement to identify a working
image. Ensure that header is present in the OTA loader.
Update the PicoOTA examples for the 2350
Several Arduino APIs realloc(NULL) which is legal and equivalent to
"malloc()", but the PSRAM logic was placing those malloc calls in PSRAM
and not RAM because "0" < RAM_START.
Ensure the realloc address is non-null and before RAM_START before
using PSRAM.
Pull in Raspberry Pi's custom RP2350 ARM and RISC-V ports for FreeRTOS.
Basic tests run, but stress mutex test is failing in unique and interesting
ways.
* Add simplified switching test catching task swap problem
* Freertosrp2350: use FreeRTOS macros in noInterrupts/interrupts when applicable. (#2456)
* Use FreeRTOS macros in noInterrupts/interrupts when applicable.
* Fixed calling taskEXIT_CRITICAL and taskENTER_CRITICAL

* Add support for the extra 16 GPIO pins in the menus and core.
* Clean up Generic RP2350 PSRAM ("none" is valid) and flash (other than 16MB) options.
* Add extra GPIO<->peripheral connections
* Add Pimoroni PGA2350 RP2350B-based board
* Pins 32-47 can be used for PIOPrograms
* Avoid hang when PSRAM fails to initialize
* Move libpico to an RP2350B board for SDK (otherwise the SDK drops all GPIOHI support)
SWSerial wasn't even building due to a typo in the header, and SerialPIO
needs to set the OE-invert flag after PIO initialization for transmit.
Fixes#2419
Use real GPIO pad inversion to allow inverted RX, TX, and controls for
the hardware UART and software PIO-emulated serial ports.
Adds ``setInvertTX(bool)`` and ``setInvertRX(bool)`` calls to both ports,
with ``setInvertControl(bool)`` for the HW UARTS.
