... which is also somewhat unfortunate. Have you ever tried to run one
of those boards to see whether you've broken something with your code
changes or not? Hunting the firmware for such a board can be quite
challenging. I'm not saying that we should now try to include way more
firmware blobs in our repository (its size would explode, I guess), but
maybe we should at least start a Wiki page with links to the various
firmware images or so?
