They are in the process of being edited by our tech writer as well as
being converted from ascii to docbook. You can see the current state of
them here:

http://www.yoctoproject.org/docs/hart/kernel-dev/kernel-dev.html

See Section 2.2.2 and the sections that follow.

Keep in mind these are being actively worked on, so there are some rough
edges we're working through still.
