Linus Torvalds dfc25e4503 ARM: SoC: cleanups for 3.15
These cleanup patches are mainly move stuff around and should all
 be harmless. They are mainly split out so that other branches can
 be based on top to avoid conflicts.
 
 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).

of individual platforms as they are redundant.
 - Make SMP, CACHE_L2X0 and GPIO config options user visible on
 multi-platform builds as most platforms enable these options and all
 platforms can run with them enabled.
 - Make multi-platform v6 default to more optimal v6k rather than v6

Jason Cooper f4d4ffc03e kbuild: dtbs_install: new make target
Unlike other build products in the Linux kernel, there is no 'make
*install' mechanism to put devicetree blobs in a standard place.

This commit adds a new 'dtbs_install' make target which copies all of
the dtbs into the INSTALL_DTBS_PATH directory. INSTALL_DTBS_PATH can be
set before calling make to change the default install directory. If not
set then it defaults to:

	$INSTALL_PATH/dtbs/$KERNELRELEASE.

This is done to keep dtbs from different kernel versions separate until
things have settled down.  Once the dtbs are stable, and not so strongly
linked to the kernel version, the devicetree files will most likely move
to their own repo.  Users will need to upgrade install scripts at that
time.

v7: (reworked by Grant Likely)
- Moved rules from arch/arm/Makefile to arch/arm/boot/dts/Makefile so
  that each dtb install could have a separate target and be reported as
  part of the make output.
- Fixed dependency problem to ensure $KERNELRELEASE is calculated before
  attempting to install
- Removed option to call external script. Copying the files should be
  sufficient and a build system can post-process the install directory.
  Despite the fact an external script is used for installing the kernel,
  I don't think that is a pattern that should be encouraged. I would
  rather see buildroot type tools post process the install directory to
  rename or move dtb files after installing to a staging directory.
  - Plus it is easy to add a hook after the fact without blocking the
    rest of this feature.
- Move the helper targets into scripts/Makefile.lib with the rest of the
  common dtb rules

Linus Torvalds 0ba3307a8e ARM: driver updates for 3.14
Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree.
 
 The largest part of this is a conversion of device registration for some
 renesas shmobile/sh devices over to use resources. This has required
 coordination with the corresponding arch/sh changes, and we've agreed
 to merge the arch/sh changes through our tree.
 
 Added in this branch is support for Trusted Foundations secure firmware,
 which is what is used on many of the commercial Nvidia Tegra products
 that are in the market, including the Nvidia Shield. The code is local
 to arch/arm at this time since it's uncertain whether it will be shared
 with arm64 longer-term, if needed we will refactor later.
 
 A couple of new RTC drivers used on ARM boards, merged through our tree
 on request by the RTC maintainer.
 
 ... plus a bunch of smaller updates across the board, gpio conversions
 for davinci, etc.

they are still in linux-next git tree. So rename ARCH_HI3xxx later.

Trusted Foundations is a TrustZone-based secure monitor for ARM that
can be invoked using the same SMC-based API on supported platforms.
This patch adds initial basic support for Trusted Foundations using
the ARM firmware API. Current features are limited to the ability to
boot secondary processors.

Note: The API followed by Trusted Foundations does *not* follow the SMC
calling conventions. It has nothing to do with PSCI neither and is only
relevant to devices that use Trusted Foundations (like most Tegra-based
retail devices).

Laurent Pinchart bf98c1eac1 ARM: Rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY
SH-Mobile platforms are transitioning from non-multiplatform to
multiplatform kernel. A new ARCH_SHMOBILE_MULTI configuration symbol has
been created to group all multiplatform-enabled SH-Mobile SoCs. The
existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't
been converted yet.

This arrangement works fine for the arch/ code, but lots of drivers
needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on
ARCH_SHMOBILE only. In order to avoid changing them, rename
ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean
ARCH_SHMOBILE configuration symbol that is selected by both
ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.

Linus Torvalds f47671e2d8 Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
 "Included in this series are:

   1. BE8 (modern big endian) changes for ARM from Ben Dooks
   2. big.Little support from Nicolas Pitre and Dave Martin
   3. support for LPAE systems with all system memory above 4GB
   4. Perf updates from Will Deacon
   5. Additional prefetching and other performance improvements from Will.
   6. Neon-optimised AES implementation fro Ard.
   7. A number of smaller fixes scattered around the place.

  There is a rather horrid merge conflict in tools/perf - I was never
  notified of the conflict because it originally occurred between Will's
  tree and other stuff.  Consequently I have a resolution which Will
  forwarded me, which I'll forward on immediately after sending this
  mail.

  The other notable thing is I'm expecting some build breakage in the
  crypto stuff on ARM only with Ard's AES patches.  These were merged
  into a stable git branch which others had already pulled, so there's
  little I can do about this.  The problem is caused because these
  patches have a dependency on some code in the crypto git tree - I
  tried requesting a branch I can pull to resolve these, and all I got
  each time from the crypto people was "we'll revert our patches then"
  which would only make things worse since I still don't have the
  dependent patches.  I've no idea what's going on there or how to
  resolve that, and since I can't split these patches from the rest of
  this pull request, I'm rather stuck with pushing this as-is or
  reverting Ard's patches.

  Since it should "come out in the wash" I've left them in - the only
  build problems they seem to cause at the moment are with randconfigs,
  and since it's a new feature anyway.  However, if by -rc1 the
  dependencies aren't in, I think it'd be best to revert Ard's patches"

I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences.  Any errors are likely mine.  Let's
see how the crypto issues work out..

 One longish patch series from Sebastian Hasselbarth changes the init_time

 Finally the "shark" platform is removed in this release. It's been
 abandoned for a while and nobody seems to care enough to keep it
 around. If someone comes along and wants to resurrect it, the removal
 can easily be reverted and code brought back.
 
 Beyond this, mostly a bunch of removals of stale content across the

of all instructions, make sure modules are built also built with --be8
(as is the current kernel final link).

If we do not do this, we would end up having to swap all instructions

Robert Richter 19514fc665 arm, kbuild: make "make install" not depend on vmlinux
Install targets (install, zinstall, uinstall) on arm have a dependency
to vmlinux. This may cause parts of the kernel to be rebuilt during
installation. We must avoid this since this may run as root. Install
targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus
emphasized this in:

 http://lkml.org/lkml/2013/7/10/600

So on arm and maybe other archs we need the same as for x86:

 1648e4f8 x86, kbuild: make "make install" not depend on vmlinux

This patch fixes this for arm. Dependencies are removed and instead a
check to install.sh is added for the files that are needed.

This issue was uncovered by this build error where the -j option is
used in conjunction with install targets:

 $ make <makeflags>
 $ make <makeflags> zinstall
 ...
   DEPMOD
 Usage: .../scripts/depmod.sh /sbin/depmod <kernelrelease>

(INSTALL_MOD_PATH and INSTALL_PATH variables set, so no root perms
required in this case.)

The problem is that zinstall on arm due to its dependency to vmlinux
does a prepare/prepare3 and finally does a forced rewrite of
kernel.release even if it exists already.

Rebuilding kernel.release removes it first and then recreates it. This
might race with another parallel make job running depmod.

So this patch should fix this one too.

Also quoting $(KERNELRELEASE) arg for install.sh as this messes
argument order in case it is empty (which is the case if the kernel
was not built yet).

Linus Walleij 136dfa5eda ARM: delete mach-shark
The Shark machine sub-architecture (also known as DNARD, the
DIGITAL Network Appliance Reference Design) lacks a maintainer
able to apply and test patches to modernize the architecture.

It is suspected that the current kernel, while it compiles,
does not even boot on this machine. The listed maintainer has
expressed that he will not be able to spend any time on the
maintenance for the coming year.

So let's delete it from the kernel for now. It can always be
resurrected with git revert if maintenance is resumed.

As the VIA82c505 PCI adapter was only used by this
architecture, that gets deleted too.

Linus Torvalds fb2af0020a Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
 "This contains the usual updates from other people (listed below) and
  the usual random muddle of miscellaneous ARM updates which cover some
  low priority bug fixes and performance improvements.

  I've started to put the pull request wording into the merge commits,
  which are:

   - NoMMU stuff:

     This includes the following series sent earlier to the list:
      - nommu-fixes
      - R7 Support
      - MPU support

     I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
     were discussing today until we've reached a conclusion/that's had
     some more review.

     This is rebased (and re-tested) on your devel-stable branch because
     otherwise there were going to be conflicts with Uwe's V7M work now
     that you've merged that.  I've included the fix for limiting MPU to
     CPU_V7.

   - Huge page support

     These changes bring both HugeTLB support and Transparent HugePage
     (THP) support to ARM.  Only long descriptors (LPAE) are supported
     in this series.

     The code has been tested on an Arndale board (Exynos 5250).

   - LPAE updates

     Please pull these miscellaneous LPAE fixes I've been collecting for
     a while now for 3.11.  They've been tested and reviewed by quite a
     few people, and most of the patches are pretty trivial.  -- Will Deacon.

   - arch_timer cleanups

     Please pull these arch_timer cleanups I've been holding onto for a
     while.  They're the same as my last posting, but have been rebased
     to v3.10-rc3.

   - mpidr linearisation (multiprocessor id register - identifies which
     CPU number we are in the system)

     This patch series that implements MPIDR linearization through a
     simple hashing algorithm and updates current cpu_{suspend}/{resume}
     code to use the newly created hash structures to retrieve context
     pointers.  It represents a stepping stone for the implementation of
     power management code on forthcoming multi-cluster ARM systems.

     It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
     OMAP4 and Tegra, with processors hitting low-power states requiring
     warm-boot resume through the cpu_resume code path"

Linus Torvalds 42daabf62b ARM SoC late changes
These are changes that arrived a little late before the merge
 window or that have multiple dependencies on previous branches
 so they did not fit into one of the earlier ones. There
 are 10 branches merged here, a total of 39 non-merge commits.
 Contents are a mixed bag for the above reasons:
 
 * Two new SoC platforms: ST microelectronics stixxxx and
   the TI 'Nspire' graphing calculator. These should have
   been in the 'soc' branch but were a little late
 * Support for the Exynos 5420 variant in mach-exynos,
   which is based on the other exynos branches to avoid
   conflicts.
 * Various small changes for sh-mobile, ux500 and davinci
 * Common clk support for MSM
 
 Conflicts:

Linus Torvalds 3883cbb6c1 ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on
 17 platforms were pulled into this. Like last time, Renesas sh-mobile
 is now the platform with the most changes, followed by OMAP and EXYNOS.
 
 Two new platforms, TI Keystone and Rockchips RK3xxx are added in
 this branch, both containing almost no platform specific code at all,
 since they are using generic subsystem interfaces for clocks, pinctrl,
 interrupts etc. The device drivers are getting merged through the
 respective subsystem maintainer trees.
 
 One more SoC (u300) is now multiplatform capable and several others
 (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
 towards that goal with this series but need more work.
 
 Also noteworthy is the work on PCI here, which is traditionally part of
 the SoC specific code. With the changes done by Thomas Petazzoni, we can
 now more easily have PCI host controller drivers as loadable modules and
 keep them separate from the platform code in drivers/pci/host. This has
 already led to the discovery that three platforms (exynos, spear and imx)
 are actually using an identical PCIe host controller and will be able
 to share a driver once support for spear and imx is added.
 
 Conflicts:
 * asm/glue-proc.h has one CPU type getting added that conflicts
   with another addition in 3.10-rc7
 * Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

Douglas Anderson 1b21376a73 ARM: 7777/1: Avoid extra calls to the C compiler
Starting up the C compiler can be a slow operation on some systems.
Though these calls don't individually take a lot of time, they add up.
Rearrange the ARM Makefile a bit to avoid extra calls to the compiler
when they can be easily avoided.

When running with the Chrome OS ARM cross compiler
"armv7a-cros-linux-gnueabi-", this shaved .55 seconds (from 5.31
seconds to 4.76 seconds) off an incremental build of the kernel:
  time make -j32 ARCH=arm CROSS_COMPILE=armv7a-cros-linux-gnueabi-

This patch-set adds basic support for STMicroelectronics STi series SOCs
which includes STiH415 and STiH416 with B2000 and B2020 board support.

STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for
use in Set-top-boxes. The SOC support is available in mach-sti which
contains support code for STiH415, STiH416 SOCs including the generic
board support.

The reason for adding two SOCs at this patch set is to show that no new
C code is required for second SOC(STiH416) support.

Arnd Bergmann c5dece37c5 ARM: sirf: use CONFIG_SIRF rather than CONFIG_PRIMA2 where necessary
I got a build error today that made me realize that it is not
possible to build a kernel for a SiRF platform without enabling
CONFIG_PRIMA2, since a lot of common code depends on CONFIG_PRIMA2.

This fixes all occurences that appear like common SiRF code.

Tomasz Figa e245f9699e ARM: EXYNOS: Decouple ARCH_EXYNOS from PLAT_S5P
After removing support for ATAGS based boot on Exynos, there is not much
that can be shared between Exynos and other S5P platforms. This patch
makes Exynos a standalone Samsung platform, not using PLAT_S5P.

Santosh Shilimkar 828989ad87 ARM: keystone: Add minimal TI Keystone platform support
Texas Instruments Keystone family of multi-core devices are
based on ARM Cortex A15. Patch adds basic definitions for a
new Keystone sub-architecture in ARM.

The TCI66xxK2H Communications Infrastructure Keystone SoCs
are member of the C66x family based on TI's new KeyStone 2
multi-core SoC Architecture designed specifically for high
performance wireless and networking infrastructure applications.
The SOCs contains many subsystems like Cortex A15 ARM CorePacs,
C66XX DSP CorePacs, MSMC memory controller, Tera Net bus,
IP Network, Navigator, Hyperlink, 1G/10G Ethernet, Radio layers
and queue based communication systems.

Russell King f150abe101 Merge branch 'for-next' of git://git.pengutronix.de/git/ukl/linux into devel-stable
Pull ARM-v7M support from Uwe Kleine-König:
"All but the last patch were in next since next-20130418 without issues.
The last patch fixes a problem in combination with

  8164f7a (ARM: 7680/1: Detect support for SDIV/UDIV from ISAR0 register)

which triggers a WARN_ON without an implemented read_cpuid_ext.

The branch merges fine into v3.10-rc1 and I'd be happy if you pulled it
for 3.11-rc1. The only missing piece to be able to run a Cortex-M3 is
the irqchip driver that will go in via Thomas Gleixner and platform
specific stuff."
