I see that the ADI Coyote was included, but not the ADI Pronghorn which actually has sufficient RAM (64MB) and flash (16MB) to run OpenWrt.  I’ll be looking at using the ADI Coyote as a base to eventually create a pull request to get the ADI Pronghorn supported! I can also test the D-Link DSM-G600 and Gateworks GW2348 support.

Thanks for starting this effort.
