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
