Due to the brcmstb SoC's memory map, we may have holes in the memory if
we don't populate the maximum amount of memory supported by e.g: the
first memory controller which spans either the first 1GiB or first 2GiB
of memory.
We need to select ARCH_HAS_HOLES_MEMORYMODEL in order to enable
CONFIG_HAVE_ARCH_PFN_VALID on platforms that have CONFIG_SPARSEMEM
enabled.

Some Host Controller hardware blocks, like the OHCI, EHCI and SDIO
controllers, have hardware blocks that are not capable of doing 64 bit
DMA. These host controllers fail on boards with >3GB of memory because
the memory above 3GB is located physically >= 0x100000000 and can only
be accessed using 64 DMA. The way Linux is currently configured for
BRCMSTB systems, the memory given to drivers for DMA through functions
like dma_alloc_coherent() comes from CMA memory and CMA memory is taken
from the top of physical memory. When these drivers get a DMA buffer
with an address >=0x100000000, they end up dropping the upper 32 bit of
the address causing the hardware to DMA to incorrect memory, typically
BMEM (custom memory carveout). This issue was discovered on a
BCM97449SSV_DDR4 system with 4GB or memory.
The fix is to enable CONFIG_ZONE_DMA. On ARM systems this makes sure
that all DMA memory is located within the first 32 bits of address
space.

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.

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".

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).

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.

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.

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.
