I tested Spring with next-20141124, and finally got it to work! :)
Thanks a lot, Ajay and Javier!
To be on the safe side, I reverted the patch pointed out by Javier and
was still using clk_ignore_unused.
Ajay, note that your rebased Snow patch has the last hunk indented one
level too deep.
I'll post a cleaned-up bridge patch for Spring later.
Cheers,
Andreas
