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 Signed-off-by: Olof Johansson <olof@lixom.net>
