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.
