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
