This will definately require a BSP layer, and I'm hoping it will build out of box with all the necessary kernel changes for intel-mid already merged into linux-3.19.
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.
