I should add that I tried to use XIP on omap (for research purposes),
but it was broken and I didn't have time to fix it.  My bad.
If anyone is using XIP on in-tree platforms, I'd like to hear
about it.

As for in-tree-ness - I thought the most recent message was to stay
out of tree until the refactoring was over. ;-)
