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."
