Merge tag 'soc_for_v3.10' of git://git.infradead.org/users/jcooper/linux into next/soc2

From Jason Cooper:
mvebu soc changes for v3.10

 - use the mvebu-mbus driver
 - prep for LPAE support

Depends:
 - mvebu/cleanup (tags/cleanup_for_v3.10)
 - mvebu/drivers (tags/drivers_for_v3.10)

* tag 'soc_for_v3.10' of git://git.infradead.org/users/jcooper/linux:
  ARM: mvebu: Align the internal registers virtual base to support LPAE
  ARM: mvebu: Limit the DMA zone when LPAE is selected
  arm: plat-orion: remove addr-map code
  arm: mach-mv78xx0: convert to use the mvebu-mbus driver
  arm: mach-orion5x: convert to use mvebu-mbus driver
  arm: mach-dove: convert to use mvebu-mbus driver
  arm: mach-kirkwood: convert to use mvebu-mbus driver
  arm: mach-mvebu: convert to use mvebu-mbus driver
  bus: mvebu: fix mistake in PCIe window target attribute for Kirkwood
  bus: mvebu-mbus: Restore checking for coherency fabric hardware
  ARM: Orion: add dbg_show function to gpio-orion driver
  bus: introduce an Marvell EBU MBus driver
  arm: mach-orion5x: use mv_mbus_dram_info() in PCI code
  arm: plat-orion: use mv_mbus_dram_info() in PCIe code
  arm: plat-orion: only build addr-map.c when needed

- * The Orion has fully programmable address map. There's a separate address
- * map for each of the device _master_ interfaces, e.g. CPU, PCI, PCIe, USB,
- * Gigabit Ethernet, DMA/XOR engines, etc. Each interface has its own
- * address decode windows that allow it to access any of the Orion resources.
- *
- * CPU address decoding --
- * Linux assumes that it is the boot loader that already setup the access to
- * DDR and internal registers.
- * Setup access to PCI and PCIe IO/MEM space is issued by this file.
- * Setup access to various devices located on the device bus interface (e.g.
- * flashes, RTC, etc) should be issued by machine-setup.c according to
- * specific board population (by using orion5x_setup_*_win()).
- *
- * Non-CPU Masters address decoding --
- * Unlike the CPU, we setup the access from Orion's master interfaces to DDR
- * banks only (the typical use case).
- * Setup access for each master to DDR is issued by platform device setup.
