Pull ARM SoC platform updates from Arnd Bergmann:
"These are updates for platform specific code on 32-bit ARM machines,
essentially anything that can not (yet) be expressed using DT files.
Noteworthy changes include:
- We get support for running in big-endian mode on two platforms:
sunxi (Allwinner) and s3c24xx (old Samsung).
- The recently added Uniphier platform now uses standard PSCI methods
for SMP booting and we remove support for old bootloader versions
that did not support it yet.
- In sunxi, we gain support for the "Nextthing GR8" SoC, which is a
close relative of the Allwinner A13 and R8 chips.
- PXA completes its move over to the generic dmaengine framework and
removes its old private API
- mach-bcm gains support for BCM47189/BCM53573, their first ARM SoC
with integrated 802.11ac wireless networking"

BCM53573 series is a new family with embedded wireless. By marketing
people it's sometimes called Northstar but it uses different CPU and has
different architecture so we need a new symbol for it.
Fortunately it shares some peripherals with other iProc based SoCs so we
will be able to reuse some drivers/bindings.

Make the clocks visible options that can be selected by anyone. This
avoids the problems of:
1) Select is a reverse dependency and is hard for people to understand
and can sometimes be a pain to track down
2) Build coverage goes down because configs are hidden
3) Code bloat

This replaces:
- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
now be selected directly.
- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
is now selectable by everyone, so we need not declare our
intent to select it.
When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Change the Kconfig option logic to fullfil with the current approach.
A new Kconfig option is added, CONFIG_BCM_KONA_TIMER and is selected by the
platform. Then the clocksource's Kconfig is changed to make this option
selectable by the user if the COMPILE_TEST option is set. Otherwise, it is
up to the platform's Kconfig to select the timer.

Do not have the machine Kconfig entry point need to select
BRCMSTB_GISB_ARB, instead, just let it be default ARCH_BRCMSTB which is
a better way to deal with this. While at it, also make it default
BMIPS_GENERIC so the legacy MIPS-based STB platforms can benefit from
the same thing.

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.
Please notice the difference between
config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7
and
config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7
These two are *not* equivalent!
In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.
The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)
For enabling/disabling sub-architectures, the latter is always correct.
As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).
[Arnd: I note that there is not really a bug here, according to
the discussion that followed, but I can see value in being consistent
and in making the lines shorter]

The BCM4708 I have, which is probably the first generation which got
to the consumer market, is using a ARM Cortex-A9 rev r3p0 and a
L2C-310 rev r3p2 L2 cache controller. There are 3 workarounds for known
erratas in the Linux kernel which could be activated and will be in
this patch. There are currently no workarounds which have to be
activated for the L2C-310 rev r3p2 in Linux.

router/gateway applications. The SoC features dual core Cortex
A9 ARM CPUs, integrating several peripheral interfaces including
multiple Gigabit Ethernet PHYs, DDR3 memory, PCIE Gen-2, USB 2.0
and USB 3.0, serial and NAND flash, SATA and several other IO
controllers.

A recent cleanup rearranged the Kconfig file for mach-bcm and
accidentally dropped the dependency on ARCH_MULTI_V7, which
makes it possible to now build the two mobile SoC platforms
on an ARMv6-only kernel, resulting in a log of Kconfig
warnings like
warning: ARCH_BCM_MOBILE selects ARM_ERRATA_775420 which has unmet direct dependencies (CPU_V7)
and which of course cannot work on any machine.
This puts back the dependencies as before.

Some chips, such as BCM6328, only require bcm7120-l2. Some BCM7xxx STB
configurations only require brcmstb-l2. Treat them as two separate

This patch adds SMP support for BCM281XX and BCM21664 family SoCs.
This feature is controlled with a distinct config option such that
an SMP-enabled multi-v7 binary can be configured to run these SoCs
in uniprocessor mode. Since this SMP functionality is used for
multiple Broadcom mobile chip families the config option is called
ARCH_BCM_MOBILE_SMP (for lack of a better name).
On SoCs of this type, the secondary core is not held in reset on
power-on. Instead it loops in a ROM-based holding pen. To release
it, one must write into a special register a jump address whose
low-order bits have been replaced with a secondary core's id, then
trigger an event with SEV. On receipt of an event, the ROM code
will examine the register's contents, and if the low-order bits
match its cpu id, it will clear them and write the value back to the
register just prior to jumping to the address specified.
The location of the special register is defined in the device tree
using a "secondary-boot-reg" property in a node whose "enable-method"
matches.

The System Type menu is getting quite long with platforms and is
inconsistent in handling of sub-arch specific options. Tidy up the menu

Pull part one of ARM SoC updates from Olof Johansson:
"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.

PCI-capable devices (e.g. mach-virt with virtio-pci).
This patch allows PCI support to be selected for these SoCs by selecting

individual selections from multi-platform enabled SoCs.

Add a new config option ARCH_BCM_MOBILE_L2_CACHE that allows support
for level-2 cache to be enabled or disabled at build time for
BCM218XX and BCM21664 family SoCs.
Build support for SMC only if it's required (currently it's only
required for to support level 2 cache control).
If arch/arm/mach-bcm/kona.c gets compiled, ARCH_BCM_MOBILE_L2_CACHE
must have been selected, which implies CONFIG_CACHE_L2X0 is set.
There is therefore no need to check CONFIG_CACHE_L2X0 at the top
of kona_l2_cache_init(), so get rid of that check.

Currently CONFIG_ARCH_BCM_MOBILE is used to select all (both)
Broadcom mobile SoC families. Instead, use that only as a config
menu switch, and define specific symbols like ARCH_BCM_281XX to
select a particular SoC family. If ARCH_BCM_MOBILE is selected, all
of the SoCs will be selected by default, but this way each can be
disabled individually as well.
Note that BCM281xx and BCM21664 both require the SMC and L2 cache
control code, so that code will be built based on ARCH_BCM_MOBILE.
