Merge tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC board specific changes from Arnd Bergmann:
"These are 18 branches on 9 platforms with board specific changes,
mostly for defconfig files, but nothing really exciting in here.
Since the shmobile platform still uses board files for some of the
newer machines, we get a few changes there as the result of drivers
getting enabled for those boards. This causes some conflicts with
contents getting added from multiple branches in sh-mobile specific
files. Renesas is putting a lot of work into migrating to device-tree
based setup, which will make all those files obsolete in the future
and avoid both the conflicts and the need to have these files in the
first place."
