Merge tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC board updates from Olof Johansson:
 "Board-related updates.  This branch is getting smaller and smaller,
  which is the whole idea so that's reassuring.

  Right now by far most of the code is related to shmobile updates, and
  they are now switching over to removal of board code and migration to
  multiplatform, so we'll see their board code base shrink in the near
  future too, I hope.

  In addition to that is some defconfig updates, some display updates
  for OMAP and a bit of new board support for Rockchip boards"
