What I did was buy a wifi router with a chipset supported by OpenWrt but with no build target yet. One of the OpenWrt maintainers then guided me in what I had to do to get the info he needed for a patch. I followed his instructions, he wrote the patch and there it was, a new build target. Later I wrote a patch myself to fix the LED control. It was a rewarding and educational experience. Later I even found someone using OpenWrt on the router I helped get supported which put a smile on my face.
