Merge tag 'soc-for-linus-3' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates (part 3) from Arnd Bergmann: "This is the third and smallest of the SoC specific updates. Changes include: - SMP support for the Xilinx zynq platform - Smaller imx changes - LPAE support for mvebu - Moving the orion5x, kirkwood, dove and mvebu platforms to a common "mbus" driver for their internal devices. It would be good to get feedback on the location of the "mbus" driver. Since this is used on multiple platforms may potentially get shared with other architectures (powerpc and arm64), it was moved to drivers/bus/. We expect other similar drivers to get moved to the same place in order to avoid creating more top-level directories under drivers/ or cluttering up the messy drivers/misc/ even more." * tag 'soc-for-linus-3' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (50 commits) ARM: imx: reset_controller may be disabled 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 ARM i.MX53: set CLK_SET_RATE_PARENT flag on the tve_ext_sel clock ARM i.MX53: tve_di clock is not part of the CCM, but of TVE ARM i.MX53: make tve_ext_sel propagate rate change to PLL ARM i.MX53: Remove unused tve_gate clkdev entry ARM i.MX5: Remove tve_sel clock from i.MX53 clock tree ARM: i.MX5: Add PATA and SRTC clocks ARM: imx: do not bring up unavailable cores ARM: imx: add initial imx6dl support ARM: imx1: mm: add call to mxc_device_init ARM: imx_v4_v5_defconfig: Add CONFIG_GPIO_SYSFS ARM: imx_v6_v7_defconfig: Select CONFIG_PERF_EVENTS ...

- * 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.
