825f4e0271 ARM: SoC updates for 3.16 (part 1)
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.

08d38bebb4 ARM: kconfig: allow PCI support to be selected with ARCH_MULTIPLATFORM
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.

1ee89e2231 ARM: mvebu: add SMP support for Armada 375 and Armada 38x
This commit adds the SMP support for Armada 375 and Armada 38x. It
turns out that the SMP logic for both of these SOCs are fairly
similar, the only differences being:

 * A different method to set the secondary CPU boot address

 * An Armada 375 specific workaround needed for the early Z1 stepping,
   added by the following patch.

Other than that, the patch is fairly straightforward and adds the
usual platsmp and headsmp code, defining the smp_operations structure
that is referenced from the DT_MACHINE structures.

8e6ac20338 ARM: mvebu: enable the ARM SCU on Armada 375 and Armada 38x
Contrary to the Armada 370 and XP that used the PJ4B Marvell cores,
the Armada 375 and Armada 38x use the ARM Cortex-A9. A consequence of
this is that the unit responsible for the coherency between CPUs is
now the ARM SCU, and not the Marvell coherency unit (which is still
present to do coherency with I/O devices).

Therefore this commit:

 * Ensures that the selection of the Armada 375 or Armada 38x SoC
   support enables the ARM SCU support in the kernel.

 * Make sure to initialize the SCU at boot time.

Lots of changes specific to one of the SoC families. Some that
 stick out are:
 
 * mach-qcom gains new features, most importantly SMP support for
   the newer chips (Stephen Boyd, Rohit Vaswani)
 * mvebu gains support for three new SoCs: Armada 375, 380 and 385
   (Thomas Petazzoni and Free-electrons team)
 * SMP support for Rockchips (Heiko Stübner)
 * Lots of i.MX changes (Shawn Guo)
 * Added support for BCM5301x SoC (Hauke Mehrtens)
 * Multiplatform support for Marvell Kirkwood and Dove
   (Andrew Lunn and Sebastian Hesselbarth doing the final part
   of a long journey)
 * Unify davinci platforms and remove obsolete ones (Sekhar Nori,
   Arnd Bergmann)

These cleanup patches are mainly move stuff around and should all

 Notable changes are:
 
 * We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
   longer used. (Uwe Kleine-König)
 * The Qualcomm MSM platform is split out into legacy mach-msm and
   new-style mach-qcom, to allow easier maintainance of the new
   hardware support without regressions. (Kumar Gala)
 * A rework of some of the Kconfig logic to simplify multiplatform
   support (Rob Herring)
 * Samsung Exynos gets closer to supporting multiplatform (Sachin
   Kamat and others)
 * mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
 * at91 gains some common clock framework support (Alexandre Belloni,
   Jean-Jacques Hiblot and other French people).

c7f094d5e8 ARM: mvebu: don't select CONFIG_NEON
CONFIG_NEON is meant to be user-selectable. Turning it on
unconditionally means we can't build a smaller kernel when
we don't need it, and causes build errors if CONFIG_VFP
is not also enabled.

To still have neon enabled however, we need to turn it on
now in multi_v7_defconfig and mvebu_v7_defconfig.

Move the kirkwood DT support into mach-mvebu, and make them part of
ARCH_MULTI_V5. Minimal changes have been made in order to make it
boot. Cleanup of the header files and integration with mvebu will
take place in following patches.

In order to help Debian transition between mach-kirkwood and
mach-mvebu, the DTS files are compiled for both, allowing Debian to
continue using mach-kirkwood until all remaining boards are supported
by mach-mvebu. Debian is then expected to simply swap from
mach-kirkwood to mach-mvebu and mach-kirkwood will be removed.

9aa30f1c13 ARM: mvebu: add initial support for the Armada 380/385 SOCs
This commit adds the basic support for the Armada 380 and Armada 385
SOCs. These SoCs share most of their IP with the Armada 370/XP
SoCs. The main difference is the use of a Cortex A9 CPU instead of the
PJ4B CPU. The Armada 380 is a single core Cortex-A9, while the Armada
385 is a dual-core Cortex-A9.

The support is introduced in board-v7.c, together with Armada 370/XP,
but a separate DT structure is added, because Armada 38x will need a
different set of SMP operations when the SMP support is introduced.

99b3d29462 ARM: mvebu: rename armada-370-xp.c to board-v7.c
In preparation to the introduction of the support of Armada 375 and
Armada 38x, this commit renames arch/arm/mach-mvebu/armada-370-xp.c to
arch/arm/mach-mvebu/board-v7.c. The board-v7.c name as we expect this
file to ultimately contain the DT_MACHINE_START definitions for all
ARMv7 Marvell EBU platforms (370, 375, 38x, XP and Dove as of today).

In relation to this file rename, this commit also:

 * Renames the hidden Kconfig symbol MACH_ARMADA_370_XP to
   MACH_MVEBU_V7. This hidden symbol is selected by the various
   per-SoC visible Kconfig options to trigger the build of board-v7.c.

 * Renames a certain number of functions in board-v7.c so that their
   armada_370_xp prefix is replaced by a mvebu prefix. The .dt_compat
   array keeps its armada_370_xp prefix because the new SOCs will be
   introduced with separate .dt_compat arrays, due to the need for
   different SMP operations.

c689cbac25 ARM: mvebu: select ARCH_REQUIRE_GPIOLIB for mvebu platform
Initially ARCH_REQUIRE_GPIOLIB was part of Thomas Petazzoni series
when he introduced the gpiolib support for mvebu:
93a59cf arm: mvebu: use GPIO support now that a driver is available

This commit was written to be applied for the ARCH_MVEBU which was
located in arch/arm/KConfig and was merged in 3.7.

In the same time Rob Herring moved the ARCH_MVEBU block to
arch/arm/mach-mvebu/Kconfig with this commit and also merged in 3.7:
387798b ARM: initial multiplatform support

Unfortunately the ARCH_REQUIRE_GPIOLIB have been lost during this
migration. This was not noticed until the v3.10-rc1, because mvebu as
part of ARCH_MULTIPLATFORM was always selected with ARCH_VEXPRESS, and
this architect selected ARCH_REQUIRE_GPIOLIB.

Since the following commit from Arnd: "883a106 ARM: default machine
descriptor for multiplatform", ARCH_VEXPRESS was then no more selected
by default with ARCH_MVEBU and it made appeared the lack of
ARCH_REQUIRE_GPIOLIB for mvebu. This commit added back the selection
of ARCH_REQUIRE_GPIOLIB for ARCH_MVEBU.

87e1bed406 arm: mach-mvebu: convert to use mvebu-mbus driver
The changes needed to migrate the mach-mvebu (Armada 370 and Armada
XP) to the mvebu-mbus driver are fairly minimal, since not many
devices currently supported on those SoCs use address decoding
windows. The only one being the BootROM window, used to bring up
secondary CPUs.

However, this BootROM window needed for SMP brings an important
requirement: the mvebu-mbus driver must be initialized at the
->early_init() time, otherwise the BootROM window cannot be setup
early enough to be ready before the secondary CPUs are started.

de4901933f arm: mm: Add support for PJ4B cpu and init routines
PJ4B is an implementation of the ARMv7 (such as the Cortex A9 for
example) released by Marvell. This CPU is currently found in
Armada 370 and Armada XP SoCs. This patch provides a support for the
specific initialization of this CPU.

46f2007c1e ARM: mvebu: fix build breaks from multi-platform conversion
Moving ARCH_MVEBU for multi-platform support caused several breakages in
recently added addr-map and pinctrl support for mvebu. This adds the
necessary selects and include paths to fix the build.

85077087d4 arm: mvebu: split Kconfig options for Armada 370 and XP
Until now, all the code for Armada 370 and XP was common, so we had a
single Kconfig option to support all boards using both SoCs. With the
addition of pinctrl drivers, this situation has changed: those two
SoCs are radically different in terms of pinctrl, so they have two
separate drivers. Since pinctrl drivers are typically select-ed from
the SoC Kconfig option, it makes sense to split the 370/XP option into
two separate options: one for Armada 370 and another for Armada XP.

We keep an hidden option selected by both ARMADA_370 and ARMADA_XP in
order to easily compile common code.

A followup patch actually makes use of this split to select the
appropriate pinctrl drivers.

387798b37c ARM: initial multiplatform support
This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:

* SMP support must be turned off because of conflicting symbols.
  Marc Zyngier has proposed a solution by adding a new SOC
  operations structure to hold indirect function pointers
  for these, but that work is currently stalled

* We turn on SPARSE_IRQ unconditionally, which is not supported
  on most platforms. Each of them is currently in a different
  state, but most are being worked on.

* A common clock framework is in place since v3.4 but not yet
  being used. Work on this is on its way.

* DEBUG_LL for early debugging is currently disabled.

* THUMB2_KERNEL does not work with allyesconfig because the
  kernel gets too big

[Rob Herring]: Rebased to not be dependent on the mass mach header rename.
As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
picoxcell, mvebu, and socfpga are converted.
