This will probably require a BSP layer, or preferably a merge into edison-src.
Since edison-src is developed without a public facing issue tracker I setup an issue on my own import of edison-src and created a ticket to see if I can find the right folks that way. This forum doesn't seem to be the right location, but I'll be linking back and forth between the two so others can find the information.
The github issue includes a few mentions to the Intel folks publicly maintaining the Intel iot-devkit libraries.
