Quite of few different groups of people interested in non-MMU ARM platforms have shown up over the years, but none seem to stay active for long. > and contains both a kernel and user space.

I used to keep one on git.kernel.org for promoting non-architectural but non-MMU specific changes to mainline. http://git.kernel.org/?p=linux/kernel/git/gerg/uclinux.git;a=summary But I have had so few changes that fit in that category that I haven't used it in quite a while.
