* Without `ranges;` the addresses below stay flash-relative: the code partition resolves
* to 0x100 instead of 0x10000100, so RP2_REQUIRES_SECOND_STAGE_BOOT is not selected (its
* Kconfig tests for 0x10000100) and the image ships without a second-stage bootloader,
* while the generated UF2 targets 0x00000100. Neither is loadable by the RP2040 boot ROM.
