OK - now i know where the documentation is i've searched last days.
A little bit OT:
It would be nice to see the pure kernel sources for Edison standalone somewhere and not only integrated in the Yocto build process. I prefer to keep things simple and to build the kernel with modules for my needs using the original procedures.
The Yocto project is not for everybodys taste. I switched to Debian (ubiLinux) and it's only one advantage to have the choice among thousands of packages in these repositories - very important for me.
Just my 2 cents, kind regards,
Manfred.
