Merge tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform support from Arnd Bergmann: "Converting more ARM platforms to multiplatform support. This time, OMAP gets converted, which is a major step since this is by far the largest platform in terms of code size. The same thing happens to the vt8500 platform." * tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: net: cwdavinci_cpdma: export symbols for cpsw remoteproc: omap: depend on OMAP_MBOX_FWK [media] davinci: do not include mach/hardware.h ARM: OMAP2+: Make sure files with omap initcalls include soc.h ARM: OMAP2+: Include soc.h to drm.c to fix compiling ARM: OMAP2+: Fix warning for hwspinlock omap_postcore_initcall ARM: multi_v7_defconfig: add ARCH_ZYNQ ARM: multi_v7_defconfig: remove unnecessary CONFIG_GPIOLIB arm: vt8500: Remove remaining mach includes arm: vt8500: Convert debug-macro.S to be multiplatform friendly arm: vt8500: Remove single platform Kconfig options ARM: OMAP2+: Remove now obsolete uncompress.h and debug-macro.S ARM: OMAP2+: Add minimal support for booting vexpress ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support ARM: OMAP2+: Disable code that currently does not work with multiplaform ARM: OMAP2+: Add multiplatform debug_ll support ARM: OMAP: Fix dmaengine init for multiplatform ARM: OMAP: Fix i2c cmdline initcall for multiplatform ARM: OMAP2+: Use omap initcalls ARM: OMAP2+: Limit omap initcalls to omap only on multiplatform kernels
