config RELEASE
    bool "Release build"
    help
      Whether this is a release build. Pass
      `-DCONFIG_RELEASE=y` to `./waf configure` to enable. Gates
      features like Memfault crash reporting that should only run on
      shipping firmware.

config RECOVERY_FW
    bool "Recovery firmware (PRF)"
    help
      Build the recovery firmware variant. Set via prj_prf.conf when
      configuring with --variant=prf; do not set manually.

config MFG
    bool "Manufacturing firmware"
    help
      Enable manufacturing-only functionality in the PRF build. PRF
      and MFG firmwares are mostly the same, so MFG builds also
      define the recovery-firmware symbols.

config PBLBOOT
    bool "PBLBOOT bootloader"
    help
      Build for the PBLBOOT bootloader: prepend the PBLBOOT image
      header to the firmware binary and assume a two-slot flash
      layout with direct XIP. Disable for boards whose SoC bootloader
      consumes a raw image and uses a single firmware slot.

      Lowercase token identifying the board family (or the single
