This completes the multi-step task of converting 4MB Espressif boards to use a single larger firmware partition, instead of having one main partition and a second OTA-update partition of the same size. The increased size of the partition allows us to turn on BLE on 4MB boards, and allow other features.

  • Fixes correct board special pin setup #9553 (last task: do ESP32-S2 boards)
  • Clean up espressif/boards/*/mpconfigboard.mk.
    • remove CIRCUITPY_ESPCAMERA = 0, which no longer needs to be done explicitly on non-PSRAM boards: it is turned off automically on those boards.
    • turn on modules on a few boards now that there is more space.
    • add comments about why some modules are turned off, mostly due to not having enough pins available

… add more modules now

- CIRCUITPY_ESPCAMERA = 0 is now automatic for boards without PSRAM, so remove explicit references.
- Restore some modules to boards now that there is more room.
- Add comments noting boards with few pins. More could be turned off on these boards, but it doesn't matter much.
