SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
for a few platforms:
* Gemini:
- Legacy platform that Linus Walleij has converted to multiplatform
and DT, so a handful of various tweaks there, removal of some old
stale support, etc.
* Atmel AT91:
- Fixup of various power management related pieces
- Move of SoC detection to a drivers/soc driver instead
* ST Micro STM32:
- New SoC support: STM32H743
* TI platforms:
- More driver support for Davinci (SATA in particular)
- Removal of some old stale hwmod files (linkspace platform)
* Misc:
- A couple of smaller patches for i.MX, sunxi, hisi

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:
- Added support for the TI DRA71x family of SoCs in mach-omap2,
this is an new variant of the the DRA72x/DRA74x automotive
infotainment chips we already supported for a while.
- Added support for the ST STM32F746 SoC, the first Cortex-M7
based microcontroller we support, related to the smaller
STM32F4 family.
- Renesas adds support for r8a7743 and r8a7745 in mach-shmobile,
see http://elinux.org/RZ-G
- SMP is now supported on the OX820 platform
- A lot of code in mach-omap2 gets removed as a follow-up to
removing support for board files in the previous release
- Davinci has some new work to improve USB support
- For i.MX, the performance monitor now supports profiling the
memory controller using 'perf'

The Sphinx transition is still creating a fair amount of work. Here we
have a number of fixes and, importantly, a proper PDF output solution,
thanks to Jani Nikula, Mauro Carvalho Chehab and Markus Heiser.
I've started a couple of new books: a driver API book (based on the old
device-drivers.tmpl) and a development tools book. Both are meant to show
how we can integrate together our existing documentation into a more
coherent and accessible whole. It involves moving some stuff around and
formatting changes, but, I think, the results are worth it. The good news
is that most of our existing Documentation/*.txt files are *almost* in RST
format already; the amount of messing around required is minimal.
And, of course, there's the usual set of updates, typo fixes, and more.

The GR8 is an SoC made by Nextthing Co, loosely based on the sun5i family.
It has a number of new controllers compared to the A10s and A13 (SPDIF, I2S),
but some controllers missing too (Ethernet, less I2C, less UARTs).

XP can provide events from two sources: watchpoints, observing traffic
on device ports and PMU looking at internal buses.
Unfortunately the sysfs definition of the PMU events was requiring
port number (instead of bus number) and direction (the buses are
unidirectional), as these fields were shared with the watchpoint event.
Although it does not introduce a major problem (port can be used as
bus alias and direction is simply ignored for XP PMU events), it's
better to fix it now, before external tools start depending on this
behaviour.

In preparation to the introduction of other SoCs in the ARMv8 Armada
EBU family, this commit tweaks the existing description of Armada 37xx
by making the core, homepage and other informations be visible "under"
the Armada 37xx item. Indeed, the new SoCs will not share the same
core or homepage.
In addition, a link to the Product Brief is added.

I'm still getting confused regarding which core specifically
is used in which SoC, so I've added some more detail to the
Marvell README file. I got most of this from random sources
on the internet, so it's possible that some of the information
is wrong, but most of it should be pretty obvious.
There are a few remaining points I could not find out:
* The CPU core in Orion 88F6183
* The difference (if any) between PJ4B-MP and PJ4C
* The naming of Feroceon/Jolteon/Flareon/Sheeva/Mohawk/PJ1/PJ4
is still confusing, as they tend to overlap.

[Thomas:
- move Armada SP out from the EBU family into its own "Storage"
family. This chip is indeed not part of the EBU family.
- fixed the URL for the Armada SP information, since the link of the
original patch no longer existed
- explicitly indicate that there is no support in upstream for the
Armada SP
- indent the "Core: " description for the Armada XP to be clearly
under the Armada XP category, so that it is clear it applies to
Armada XP only, and not other cores of the EBU family.]

This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings several
of the more minor and older platforms we have closer to multiplatform
support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
Much of this is moving around header files from old mach directories,
but there are also some cleanup patches of debug_ll (lowlevel debug
per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts.

Currently kernel crash randomly when K2L EVM is booted without
clk_ignore_unused in the bootargs. This workaround is not needed
on other K2 devices such as K2HK and K2E and with this fix, we can
remove the workaround altogether. netcp driver on K2L uses linked
ram on OSR (On chip Static RAM) and requires the clock to this peripheral
enabled for proper functioning. This is the reason for the kernel crash.
So add the clock node to fix this issue.
While at it, remove the workaround documentation as well.
With the fix applied, clk_summary dump shows the clock to OSR enabled.

"In this ARM merge, we remove more lines than we add. Changes include:
- Enable imprecise aborts early, so that bus errors aren't masked
until later in the boot. This has the side effect that boot
loaders which provoke these aborts can cause the kernel to crash
early in boot, so we install a handler to report this event around
the site where these are enabled.
- Remove the buggy but impossible to enable cmpxchg syscall code.
- Add unwinding annotations to some assembly code.
- Add support for atomic half-word exchange for ARMv6k+.
- Reduce ioremap() alignment for SMP/LPAE cases where we don't need
the large alignment.
- Addition of an "optimal" 3G configuration for systems with 1G of
RAM.

writable.
- Improve ARMs dma_mmap() support for mapping DMA coherent mappings
into userspace.
- Fix to the NMI backtrace code in the IPI case on ARM where the

Update the documentation about:
1. Usage of PMU_SPARE2 register.
Bootloaders on Exynos542x-based boards often use the register
PMU_SPARE2 (0x908) in the same way as on Exynos3250: as a indicator
the secondary CPU was booted on. The bootloader will set this value
to non-zero, after sucessfull power up of secondary CPU. In the same
time this booted CPU will stuck (spin) waiting for software reset.
2. Exynos542x entry address for secondary CPU boot up after system
suspend (with MCPM enabled and in non-secure mode).

Currently firmware file name is included in the DTS. This is not scalable
as user has to change the DTS if they need upgrade to a new firmware.
Instead, add the firmware file name in the driver itself. As long as there
is no API change, new firmware upgrade is easy and require no driver
change. User is expected to copy the firmware image to the file system
and add a sym link to the new firmware for doing an upgrade. Driver add
a array of firmware file names to search for the available firmware blobs.
This scheme also prepare the driver for future changes to API if ever
happens. In such case it is assumed that driver needs to change to
accommodate the new firmware and new firmware file name will get added to
the array.
Also update the DT document to remove the firmware attribute and add
description about firmware in the driver documentation.
