A lot of reasons:
* Support 2.0 and 2.4 kernels configs and app/vendors configs with
* support uClibc/uC-libc and possibly glibc, again config selectable
* Get all the compiler/build info into one file (config.arch)
* Easily support processors other than m68k
* clean up the vendors area a little
and lastly but most importantly, do what "we", the people creating it,
need the tree to do :-)
> 2. Why was there no documentation to support this?
I can only speak for the colfire/uClinux-distribution, but mostly, we are
just too busy to write doco that the people here do not need. We are not
charging for the distro and we help out when we can ;-)

I appologise, I actually meant to make the point that this was based on the
old distribution back then, but at the time a lot of people were still working
on that release, and as such your document was correct ;-)

I agree, and I guess some of us get a little tired answering questions
that are in the mail archives several times already. I think most people's
simple questions are answered quite well on the list.

Hang in there, I'm sure we'll get something happening on the doco front ;-)
