Merge branch 'kirkwood/boards' of git://git.infradead.org/users/jcooper/linux into late/kirkwood

* 'kirkwood/boards' of git://git.infradead.org/users/jcooper/linux:
  ARM: Dove: allow PCI to be disabled
  ARM: dove: SolidRun CuBox DT
  ARM: dove: add device tree descriptors
  ARM: dove: add device tree based machine descriptor
  ARM: dove: add crypto engine
  ARM: dove: add clock gating control
  ARM: dove: unify clock setup
  ARM: initial DTS support for km_kirkwood
  arm: add documentation describing Marvell families of SoC
  ARM: kirkwood: DT descriptor for Seagate FreeAgent Dockstar
  ARM: kirkwood: DT board setup for Seagate FreeAgent Dockstar
  ARM: Kirkwood: Iomega ix2-200 DT support

Context conflicts in arch/arm/Kconfig and arch/arm/mach-dove/common.c.

The new device trees added to arch/arm/mach-kirkwood/Makefile.boot are
kept and dealt with in a separate changeset, since moving them out to
the new Makefile in this merge commit doesn't work well.
