Merge tag 'omap-for-v3.13/board-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/boards
From Tony Lindgren:
Platform data changes for omaps for the display subsystem and
n900 secure mode changes. Note that the n900 secure mode changes
will still be needed for device tree based booting also.
