RP2350 is Raspberry Pi's newest SoC. From the datasheet: "RP2350 is a new family of microcontrollers from Raspberry Pi that offers significant enhancements over RP2040. Key features include: • Dual Cortex-M33 or Hazard3 processors at 150 MHz • 520 kB on-chip SRAM, in 10 independent banks • 8 kB of one-time-programmable storage (OTP) • Up to 16 MB of external QSPI flash/PSRAM via dedicated QSPI bus ... " This commit introduces some changes to support the existing RP2040 and what is describe by Raspberry Pi as the "RP2350 family". Currently there are 4 published products in the family: RP2350A, RP2350B, RP2354A, and RP2354A. Within Zephyr's taxonomy, split the configuration as follows: Family: Raspberry Pi Pico. This contains all RP2XXX SoCs, SoC Series: RP2040 and RP2350. SoC: RP2040 and, for now, just the RP2350A, which is present on the Pico 2, where the A suffix indicates QFN-60 package type. This structure is reflected in `soc/raspberrypi/soc.yml`, and somewhat assumes that there won't be a RP2050, for example, as a RP2040 with more RAM. This is foundation work ahead of introducing support for Raspberry Pi's Pico 2 board, which is fitted with a RP2350A and 4MB of flash.
