This patch allows to build the Kernel for Vybrid (VF6xx) SoC
when ARMv7-M CPU is selected. The resulting image runs on the
secondary Cortex-M4 core. This core has equally access to all
peripherals as the main Cortex-A5 core. However, there is no
resource control mechanism, hence when both cores are used
simultaneously, orthogonal device tree's are required.
The boot CPU is dependent on the SoC variant. The available
boards use mostly variants where the Cortex-A5 is the primary
and hence the boot CPU. Booting the secondary Cortex-M4 CPU
needs SoC specific registers written. There is no in kernel
support for this right now, a external userspace utility
called "m4boot" can be used to boot the kernel:
m4boot xipImage initramfs.cpio.lzo vf610m4-colibri.dtb

When generic pm domain support is enabled, the PGC can be used
to completely gate power to the PU power domain containing GPU3D,
GPU2D, and VPU cores.
This code triggers the PGC powerdown sequence to disable the GPU/VPU
isolation cells and gate power and then disables the PU regulator.
To reenable, the reverse powerup sequence is triggered after the PU
regulator is enabled again.
The GPU and VPU devices in the PU power domain temporarily need
to be clocked during powerup, so that the reset machinery can work.

This adds support for Vybrid's interrupt router. On VF6xx models,
almost all peripherals can be used by either of the two CPU's,
the Cortex-A5 or the Cortex-M4. The interrupt router routes the
peripheral interrupts to the configured CPU.
This IRQ chip driver configures the interrupt router to route
the requested interrupt to the CPU the kernel is running on.
The driver makes use of the irqdomain hierarchy support. The
parent is given by the device tree. This should be one of the
two possible parents either ARM GIC or the ARM NVIC interrupt
controller. The latter is currently not yet supported.
Note that there is no resource control mechnism implemented to
avoid concurrent access of the same peripheral. The user needs
to make sure to use device trees which assign the peripherals
orthogonally. However, this driver warns the user in case the
interrupt is already configured for the other CPU. This provides
a poor man's resource controller.

This is the bulk of new SoC enablement and other platform changes for 3.17:
* Samsung S5PV210 has been converted to DT and multiplatform
* Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
* Kirkwood, one of the popular Marvell platforms, is folded into the
mvebu platform code, removing mach-kirkwood.
* Hwmod data for TI AM43xx and DRA7 platforms.
* More additions of Renesas shmobile platform support
* Removal of plat-samsung contents that can be removed with S5PV210 being
multiplatform/DT-enabled and the other two old platforms being removed.
New platforms (most with only basic support right now):
* Hisilicon X5HD2 settop box chipset is introduced
* Mediatek MT6589 (mobile chipset) is introduced
* Broadcom BCM7xxx settop box chipset is introduced
+ as usual a lot other pieces all over the platform code.

Merge tag 'soc-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"This is the bulk of new SoC enablement and other platform changes for
3.17:
- Samsung S5PV210 has been converted to DT and multiplatform
- Clock drivers and bindings for some of the lower-end i.MX 1/2
platforms
- Kirkwood, one of the popular Marvell platforms, is folded into the
mvebu platform code, removing mach-kirkwood
- Hwmod data for TI AM43xx and DRA7 platforms
- More additions of Renesas shmobile platform support
- Removal of plat-samsung contents that can be removed with S5PV210
being multiplatform/DT-enabled and the other two old platforms
being removed
New platforms (most with only basic support right now):
- Hisilicon X5HD2 settop box chipset is introduced
- Mediatek MT6589 (mobile chipset) is introduced
- Broadcom BCM7xxx settop box chipset is introduced
+ as usual a lot other pieces all over the platform code"

Since the OPP layer is a kernel library which has been converted to be
directly selectable by its callers rather than user selectable and
requiring architectures to enable it explicitly the ARCH_HAS_OPP symbol
has become redundant and can be removed. Do so.

After moving SOC_IMX51 support over to device tree, all i.MX5 support
becomes device tree only now. So options SOC_IMX5 and SOC_IMX51 can

Pull ARM fixes from Russell King:
"A number of low impact fixes, the most noticable one is the thumb2
frame pointer fix. We also fix a regression caused during this merge
window with ARM925 CPUs running with caches disabled, and fix a number
of warnings"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: arm925: ensure assembly sets up writethrough mapping
ARM: perf: fix compiler warning with gcc 4.6.4 (and tidy code)
ARM: l2c: fix dependencies on PL310 errata symbols
ARM: 8069/1: Make thread_save_fp macro aware of THUMB2 mode
ARM: 8068/1: scoop: Remove unused variable
A number of configurations spit out warnings similar to:
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_588369 which has unmet direct dependencies (CACHE_L2X0)
warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)
Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
eventually get rid of CACHE_PL310, surround these errata options with an
if CACHE_L2X0 conditional rather than repeating the dependency against
each.

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.

A quite large set of SoC updates this cycle. In no particular order:
- Multi-cluster power management for Samsung Exynos, adding support for
big.LITTLE CPU switching on EXYNOS5
- SMP support for Marvell Armada 375 and 38x
- SMP rework on Allwinner A31
- Xilinx Zynq support for SOC_BUS, big endian
- Marvell orion5x platform cleanup, modernizing the implementation and
moving to DT.
- _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
that their platform can be enabled in the same kernel binary as most
of the other v7 platforms in the tree. \o/ The work isn't quite complete,
there's some driver fixes still needed, but the basics now work.
New SoC support added:
- Freescale i.MX6SX
- LSI Axxia AXM55xx SoCs
- Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
- STi STIH407
Plus a large set of various smaller updates for different platforms. I'm
probably missing some important one here.

When targetting ARCH_MULTIPLATFORM, we may include support for SoCs with
PCI-capable devices (e.g. mach-virt with virtio-pci).
This patch allows PCI support to be selected for these SoCs by selecting
CONFIG_MIGHT_HAVE_PCI when CONFIG_ARCH_MULTIPLATFORM=y and removes the
individual selections from multi-platform enabled SoCs.

Booting a mx6q system built with multi_v7_defconfig leads to the following
error messages on boot:
[ 0.037758] imx6q_ocram_suspend_init: ocram pool unavailable!
[ 0.037768] imx6_pm_common_init: failed to initialize ocram suspend -19!
This happens because CONFIG_SRAM is not selected by default in
multi_v7_defconfig.
Fix this by selecting CONFIG_SRAM at ARCH_MXC level, so that other SoCs could
use the SRAM driver as well.
As SRAM automatically selects GENERIC_ALLOCATOR, just drop it from the Kconfig
entry.
