This is what I used to do, until non backward compatible changes were
introduced circa 2.6.29-2.6.30 in the bootloader and kernel support
which ended up requiring a more recent toolchain and uclinux-dist tree.

You will find the kernel commit mentioned in that tree:
git://git.kernel.org/pub/scm/linux/kernel/git/vapier/blackfin.git

This tree is maintained by Mike Frysinger; this is the source of what is
submitted upstream for inclusion blackfin-wise.

I pull the uclinux-dist code from a git tree mirroring the project's SVN
repo, the related commit number applies there:
git://sources.blackfin.uclinux.org/git/readonly-mirrors/uclinux-dist.git
