If you can make LEON stable before starting the code removal that would
be the best way forward. Then it should be easier to identify when
the removal patches breaks things.
With all the surgery I had to do to remove stuff it would have been a
big surprise if it just worked - so it goes as expected. qemu only
verify so much - the real target (and SMP) is way better.

If this round could be used to stabilize LEON and apply other more
trivial stuff, then I am happy to rebase the "sunset" patchset sometimes
after next -rc1.
I have accumulated a bit more on top of what I already posted, and I
will include a few more patches in the next round.
In other words - take your time!
