soc: rp2350: Add initial support for the Raspberry Pi RP2350
Browse files Browse the repository at this point in the history 
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
the new "RP2350 family". Currently there are 4 published products in the
family: RP2350A, RP2350B, RP2354A, and RP2354A. For now, split the
configuration into RP20XX and RP23XX. This is foundation work ahead of
introducing support for Raspberry Pi's Pico 2 board, which is fitted
with a RP2350 and 4MB of flash.
