* 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

// This example overwrites itself with a serial blinker sketch using OTA
|
|
// In general, you will get a file from the Internet, over a serial port, etc.
|
|
// and not include it in a header like we do here for simplicity.
|
|
//
|
|
// You need to have at least 256K of filesystem configured in
|
|
// Tools->Flash Size
