Patch: m68k target documentation
- To: <gcc-patches at gcc dot gnu dot org>

Hi,
This patch adds the documentation strings to the m68k target, I've tested
this together with the other patches.
It's mostly copied it from other places and I left 'sky' empty, as I don't
know it and so I don't know how to document it.
bye, Roman
