Linus Torvalds 150a8dcf10 ARM: arm-soc board specific changes for 3.10, part 1 
These changes are all for board specific files. These used to make up a
 large portion of the ARM changes in the past, but as we are generalizing
 the support and moving to device tree probing, this has gotten
 significantly smaller. The only platform actually adding new code here
 at the moment is Renesas shmobile, as they are still busy converting
 their code to device tree and have not come far enough to not need it.

Pull ARM SoC board specific changes (part 1) from Olof Johansson:
 "These changes are all for board specific files.  These used to make up
  a large portion of the ARM changes in the past, but as we are
  generalizing the support and moving to device tree probing, this has
  gotten significantly smaller.

  The only platform actually adding new code here at the moment is
  Renesas shmobile, as they are still busy converting their code to
  device tree and have not come far enough to not need it."
