I’ll have a look at it and will see what I can do. Also, thanks for your offer to answer my questions, I really appreciate it. I was thinking of FDT for the Ralink/Mediatek support, but I figured it would be beneficial to see if there is interest in these platforms at all in the community or not, so that’s why I first started working on adding basic support for more SoCs before trying to move to FDT (although I agree that moving to FDT first may have been wiser :-)). I am willing to work on moving the Ralink/Mediatek family support to FDT and doing more work on supporting currently unsupported peripherals (as far as I can be of any use), but I would only do so if the changes I make would end up committed to FreeBSD - I have no interest in doing something that will go unused by anyone… So if any committer is willing to suffer going through my patches and getting them in the tree - I’ll do my best, provided I have some spare cycles to work on this. I am also willing to do the commits myself (under proper supervision, of course) if my work is considered useful and of acceptable standards. Best wishes, Stanislav
