Linus Torvalds f6a26ae769 arm-soc: board specific changes
While we generally attempt to get rid of board specific files and replace
 them with device tree based descriptions, a lot of platforms have not
 come that far:
 
 In shmobile, we add two new board files because their recently started
 effort to add DT support has not proceeded enough to use it for all of
 the important hardware.
 
 In Kirkwood, we are adding support for new boards with a combination of
 DT and board file contents in multiple cases.
 
 pxa/mmp and imx are extending support for existing board files but not
 adding new ones.

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

Pull arm-soc board specific changes from Olof Johansson:
 "While we generally attempt to get rid of board specific files and
  replace them with device tree based descriptions, a lot of platforms
  have not come that far:

  In shmobile, we add two new board files because their recently started
  effort to add DT support has not proceeded enough to use it for all of
  the important hardware.

  In Kirkwood, we are adding support for new boards with a combination
  of DT and board file contents in multiple cases.

  pxa/mmp and imx are extending support for existing board files but not
  adding new ones."
