BBB kernel repos relationships


Can someone explain me the differences between the kernel repos for BBB (from ti, from meta-beagleboard and from Robert)? Which is the best supported?

I’m using OE/Yocto with meta-beagleboard, and I’m not be able to use a webcam.

Googling around I found some guys using the kernel from Robert C. Nelson. So I decided to test it. And for my surprise, it worked.
