Robert Richter d38726c485 dts, arm/arm64: Remove dtbs build rules in sub-makes
Add dtb files to build targets and let kbuild handle them. Thus,
special dtbs rules can be removed. This eases Makefiles and the
implementation of the support of vendor dtb subdirectories.

Robert Richter 9fb5e53722 dts, kbuild: Factor out dtbs install rules to Makefile.dtbinst
Move dtbs install rules to Makefile.dtbinst. This change is needed to
implement support for dts vendor subdirs. The change makes Makefiles
easier and smaller as no longer the dtbs_install rule needs to be
defined. Another advantage is that install goals are not encoded in
targets anymore (%.dtb_dtbinst_).

Uwe Kleine-König c3c963e1fb ARM: 8161/1: footbridge: select machine dir based on ARCH_FOOTBRIDGE
Syntactically FOOTBRIDGE and ARCH_FOOTBRIDGE are identical (the former
is defined in an if ARCH_FOOTBRIDGE block and the latter selects the
former).

Sematically FOOTBRIDGE means "we have a DC21285 (aka footbridge) device
in the system" and ARCH_FOOTBRIDGE is the support for boards with a
footbridge device, so ARCH_FOOTBRIDGE is the better symbol here.

Linus Torvalds b3345d7c57 ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
 
 * Samsung S5PV210 has been converted to DT and multiplatform
 * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
 * Kirkwood, one of the popular Marvell platforms, is folded into the
   mvebu platform code, removing mach-kirkwood.
 * Hwmod data for TI AM43xx and DRA7 platforms.
 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being
   multiplatform/DT-enabled and the other two old platforms being removed.
 
 New platforms (most with only basic support right now):
 
 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced
 
 + as usual a lot other pieces all over the platform code.

Linus Torvalds 44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

Matthias Brugger f682a21854 arm: add basic support for Mediatek MT6589 boards
This adds a generic devicetree board file and a dtsi for boards
based on MT6589 SoCs from Mediatek.

Apart from the generic parts (gic, clocks) the only component
currently supported are the timers.

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.

Since some new Hisilicon SoCs are not named as hi3xxx, rename mach-hi3xxx
to mach-hisi instead. And the pronounciation of "hisi" is similar to the
chinese pronounciation of Hisilicon. So Hisilicon guys like this name.

ARCH_HI3xxx will be renamed later since other drivers are using it and
they are still in linux-next git tree. So rename ARCH_HI3xxx later.

Alexandre Courbot d9a1beaa10 ARM: add basic support for Trusted Foundations
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..

Linus Torvalds 21604cdcdc ARM: SoC cleanups for 3.13
This branch contains code cleanups, moves and removals for 3.13.
 
 Qualcomm msm targets had a bunch of code removal for legacy non-DT
 platforms. Nomadik saw more device tree conversions and cleanup of old
 code. Tegra has some code refactoring, etc.
 
 One longish patch series from Sebastian Hasselbarth changes the init_time
 hooks and tries to use a generic implementation for most platforms,
 since they were all doing more or less the same things.
 
 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
 board, etc.

Ben Dooks 0ab89d0bf8 ARM: set --be8 when linking modules
To avoid having to make every text section swap the instruction order
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
when loading a module, instead of just the instructions that we are
applying ELF relocations to.

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.

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"

 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.

Rearrange the ARM Makefile a bit to avoid extra calls to the compiler

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.

Heiko Stuebner d63dc0514d arm: add basic support for Rockchip RK3066a boards
This adds a generic devicetree board file and a dtsi for boards
based on the RK3066a SoCs from Rockchip.

Apart from the generic parts (gic, clocks, pinctrl) the only components
currently supported are the timers, uarts and mmc ports (all DesignWare-
based).

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.

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

Linus Torvalds 8b5628ab83 arm-soc: virtualization changes
This contains parts of the ARM KVM support that have dependencies on
 other patches merged through the arm-soc tree. In combination with
 patches coming through Russell's tree, this will finally add full
 support for the kernel based virtual machine on ARM,  which has
 been awaited for some time now.
 
 Further, we now have a separate platform for virtual machines
 and qemu booting that is used by both Xen and KVM, separating
 these from the Versatile Express reference implementation.
 Obviously, this new platform is multiplatform capable so it
 can be combined with existing machines in the same kernel.

Linus Torvalds b274776c54 arm-soc: cleanups
A large number of cleanups, all over the platforms. This is dominated
 largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
 others moving code out of arch/arm into more appropriate subsystems.
 The clocksource and irqchip drivers are now abstracted to the point
 where platforms that are already cleaned up do not need to even specify
 the driver they use, it can all get configured from the device tree
 as we do for normal device drivers. The clocksource changes basically
 touch every single platform in the process.
 
 We further clean up the use of platform specific header files here,
 with the goal of turning more of the platforms over to being
 "multiplatform" enabled, which implies that they cannot expose
 their headers to architecture independent code any more.
 
 It is expected that no functional changes are part of the cleanup.
 The overall reduction in total code lines is mostly the result of
 removing broken and obsolete code.

Kukjin Kim 09ec1d7ea6 ARM: S3C24XX: Remove plat-s3c24xx directory in arch/arm/
This patch is for just moving plat-s3c24xx/*.c into mach-s3c24xx/, so
that we could remove plat-s3c24xx directory. But since the PLAT_S3C24XX
is used in drivers, the statement is not deleted and it will be sorted
out next time.

Marc Zyngier 2a0ba73880 ARM: Dummy Virtual Machine platform support
Add support for the smallest, dumbest possible platform, to be

It only mandates a GIC and architected timers. Fits nicely with
a multiplatform zImage. Uses very little silicon area.

Linus Torvalds b8edf848e9 ARM: arm-soc: multiplatform conversion patches
Here are more patches in the progression towards multiplatform, sparse
 irq conversions in particular.
 
 Tegra has a handful of cleanups and general groundwork, but is
 not quite there yet on full enablement.
 
 Platforms that are enabled through this branch are VT8500 and Zynq. note
 that i.MX was converted in one of the earlier cleanup branches as
 well (before we started a separate topic for multiplatform). And both
 new platforms for this merge window, sunxi and bcm, were merged with
 multiplatform support enabled.

This contains the bulk of new SoC development for this merge window.
 
 Two new platforms have been added, the sunxi platforms (Allwinner A1x
 SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
 series of ARMv7 platforms from them, where the hope is that we can
 keep the platform code generic enough to have them all share one mach
 directory. The new Broadcom platform is contributed by Christian Daudt.
 
 Highbank has grown support for Calxeda's next generation of hardware,
 ECX-2000.
 
 clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
 taken on maintainership of the platform.
 
 Beyond this there has been a bunch of work from a number of people on
 converting more platforms to IRQ domains, pinctrl conversion, cleanup
 and general feature enablement across most of the active platforms.

Will Deacon e91b36efe5 ARM: 7592/1: nommu: prevent generation of kernel unaligned memory accesses
Recent ARMv7 toolchains assume that unaligned memory accesses will not
fault and will instead be handled by the processor.

For the nommu case (without an MPU), memory will be treated as
strongly-ordered and therefore unaligned accesses may fault regardless
of the SCTLR.A setting.

This patch passes -mno-unaligned-access to GCC when compiling for nommu
targets, preventing the generation of unaligned memory access in the
kernel.

Christian Daudt 8ac49e0485 Add support for generic BCM SoC chipsets
In order to start upstreaming Broadcom SoC support, create
a starting hierarchy, arch and dts files.
The first support SoC family that is planned is the
BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile
SoC cores.
This code is just the skeleton code for get the machine upstreamed. It
has been made MULTIPLATFORM compatible.
Next steps
----------
Upstream a basic set of drivers - sufficient for a console boot to
ramdisk. These will includer timer, gpio, i2c drivers.
After this basic set, we will proceed with a more comprehensive set
of drivers for the 281XX SoC family.

v2 patch mods
--------
 - Remove l2x0_of_init call as there were problems with the code.
   A separate patch will be submitted with cache init code
 - Rename capri files and refs to bcm281xx-based names
 - Add bcm281xx binding doc
 - various misc cleanups

v3 patch mods
-------------
 - Remove extra #include lines
 - Remove remaining references to capri
 - dt uart chipset string added
 - cleaned up chip # references

v4 patch mods
-------------
 - swap order of compatible definitions for uart
 - fix typo

v5 patch mods
-------------
 - Rename bcm281xx to bcm11351 in dts+code,
   leaving references to bcm281xx only in help+comments.

v6 patch mods
-------------
 - fix typo in uart 'compatible' string

Linus Walleij 694e33a7f4 ARM: plat-nomadik: move MTU, kill plat-nomadik
This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.

As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.

After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.

Josh Cartwright f7977939e9 zynq: remove use of CLKDEV_LOOKUP
The Zynq support in mainline does not (yet) make use of any of the
generic clk or clk lookup functionality.  Remove what is upstream for
now, until the out-of-tree implementation is in suitable form for
merging.

An important side effect of this patch is that it allows the building of
a Zynq kernel without running into unresolved symbol problems:

   drivers/built-in.o: In function `amba_get_enable_pclk':
   clkdev.c:(.text+0x444): undefined reference to `clk_enable'
   drivers/built-in.o: In function `amba_remove':
   clkdev.c:(.text+0x488): undefined reference to `clk_disable'
   drivers/built-in.o: In function `amba_probe':
   clkdev.c:(.text+0x540): undefined reference to `clk_disable'
   drivers/built-in.o: In function `amba_device_add':

   drivers/built-in.o: In function `pm_clk_resume':
   clkdev.c:(.text+0x29c28): undefined reference to `clk_enable'
   make[2]: *** [vmlinux] Error 1
   make[1]: *** [sub-make] Error 2
   make: *** [all] Error 2

In addition, eliminate Zynq's "use" of the versatile platform, as it is
no longer needed.  As Nick Bowler points out:

   For the record, I think this was introduced by commit 56a34b03ff
   ("ARM: versatile: Make plat-versatile clock optional") which forgot to
   select PLAT_VERSATILE_CLOCK on Zynq.  This is not all that surprising,
   because the fact that Zynq "uses" PLAT_VERSATILE is secretly hidden in
   the Makefile.

   Nevertheless, the only feature from versatile that Zynq needed was the
   clock support, so this patch should *also* delete the secret use of
   plat-versatile by removing this line from arch/arm/Makefile:

      plat-$(CONFIG_ARCH_ZYNQ)      += versatile

Shawn Guo 3995eb8205 ARM: imx: merge plat-mxc into mach-imx
It's really unnecessary to have plat-mxc, and let's merge it into
mach-imx.  It's pretty much just a bunch of file renaming and
Kconfig/Makefile merge.

To make the change less invasive, we keep using Kconfig symbol
CONFIG_ARCH_MXC for mach-imx sub-architecture.
