I've been trying diligently for a couple weeks now to reach out to Intel to find the community or forum to discuss the development of the Edison BSP.
The Intel BSP's appear to be maintained by Nitin Kamble
https://www.yoctoproject.org/about/governance/technical-leadership
- Intel BSPs - Nitin Kamble
http://layers.openembedded.org/layerindex/branch/master/layer/meta-intel
is listed as the "Official layer for the Intel platform/board support" but does not include the sources use to create the BSP edison*ww42-14.tgz
If the edison-src BSP layer were an opensource project (similar to https://github.com/intel-iot-devkit/mraa/issues), we'd have a Wiki, tickets, and a way to engage with intel in a developer friendly manner.
