This way we can easily check with 'diff' for differences in our code and Atmel softpack. Also, this layout is more suitable for building various different firmware images (e.g. factory-test, dfu-loader, main application) for a variety of different boards (simtrace, owhw, qmod).

/* Code to read/track the status of the WWAN LEDs of attached modems

|
*
|
|
* Depending on the board this is running on, it might be possible
|
|
* for the controller to read the status of the WWAN LED output lines of
|
|
* the cellular modem. If the board supports this, it sets the
|
|
* PIN_WWAN1 and/or PIN_WWAN2 defines in its board.h file.
