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.

+ARM Marvell SoCs
+================
+
+This document lists all the ARM Marvell SoCs that are currently
+supported in mainline by the Linux kernel. As the Marvell families of
+SoCs are large and complex, it is hard to understand where the support
+for a particular SoC is available in the Linux kernel. This document
+tries to help in understanding where those SoCs are supported, and to
+match them with their corresponding public datasheet, when available.

+      the later PXA95x were developed by Marvell.
+
+    * Due to their XScale origin, these SoCs have virtually nothing in

+      SoCs, except with the MMP/MMP2 family of SoCs.

+
+Long-term plans
+---------------
+
+ * Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ and
+   mach-kirkwood/ into the mach-mvebu/ to support all SoCs from the
+   Marvell EBU (Engineering Business Unit) in a single mach-<foo>
+   directory. The plat-orion/ would therefore disappear.
+
+ * Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
+   directory. The plat-pxa/ would therefore disappear.
