Merge tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead." Fix conflicts as per Olof. * tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (51 commits) ARM: add v7 multi-platform defconfig ARM: msm: Move core.h contents into common.h ARM: highbank: call highbank_pm_init from .init_machine ARM: dtb: move all dtb targets to common Makefile ARM: spear: move platform_data definitions ARM: samsung: move platform_data definitions ARM: orion: move platform_data definitions ARM: vexpress: convert to multi-platform ARM: initial multiplatform support ARM: mvebu: move armada-370-xp.h in mach dir ARM: vexpress: remove dependency on mach/* headers ARM: picoxcell: remove dependency on mach/* headers ARM: move all dtb targets out of Makefile.boot ARM: picoxcell: move debug macros to include/debug ARM: socfpga: move debug macros to include/debug ARM: mvebu: move debug macros to include/debug ARM: vexpress: move debug macros to include/debug ARM: highbank: move debug macros to include/debug ARM: move debug macros to common location ARM: make mach/gpio.h headers optional ...
