@deffn {Flash Driver} {rp2040}
Supports RP2040 "Raspberry Pi Pico" microcontroller.
RP2040 is a dual-core device with two CM0+ cores. Both cores share the same
Flash/RAM/MMIO address space. Non-volatile storage is achieved with an
external QSPI flash; a Boot ROM provides helper functions.
@deffn {Flash Driver} {rp2xxx}
Supports RP2040 "Raspberry Pi Pico" microcontroller and RP2350 Pico 2
RP2040 is a dual-core device with two CM0+ cores.
RP2350 is a dual-core device with two slots switched to either Cortex-M33
or Hazard3 RISC-V core.
Both cores share the same Flash/RAM/MMIO address space.
Non-volatile storage is achieved with an external QSPI flash;
a Boot ROM provides helper functions.
