It depends. Any questions regarding the ARM kernel should be on the
arm-linux-kernel (also CCed now), since the nommu support is merged
with the mainline kernel.

uClinux seems to be rather focused on m68knommu (coldfire) these days,
and contains both a kernel and user space. The last uClinux release
containst some changes for Samsung platforms (s3c24a0, s3c3410,
s3c44b0x and s5c7375). It's probably a good idea to look at that
code for reference, but I would suggest integrating the code for
your platform in the upstream  tree directly.

I could not find a git tree for uClinux that contains any recent
kernel. Does that exist?
