Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Kevin Hilman:
 "A relatively small setup of cleanups this time around, and similar to
  last time the bulk of it is removal of legacy board support:

   - OMAP: removal of legacy (non-DT) booting for several platforms

   - i.MX: remove some legacy board files"
