This commit accidentally reverted r349333, r349334, r349335, r349336,
r349339, r349340, r349341 and r349342. I rebased after one of the make
universes I did to proof this set and something must have gone wrong and I
lost these changes. I noticed while committing, but didn't hit ^C fast
enough to prevent the damage it seems.

I've reapplied those changes rather than revert this commit for two
reasons: first, reverting commits that delete things has caused me trouble
in the past. Second, I judge that to be less repo-churn than doing the
revert, then redoing the nand* removal.

Time was of the essence, so I hope my snap-judgement was sound. My
apologies both for the 'oops' and for any other fallout.
