Merge tag 'arm-soc-imx-move' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Consolidate i.MX 5 platforms to be under the new shared i.MX 3/5/6 tree.

* tag 'arm-soc-imx-move' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM i.MX: Update defconfig
  ARM i.MX: Merge i.MX5 support into mach-imx
  ARM i.MX5: remove unnecessary includes from board files

Fix up fairly trivial conflicts due to various changes nearby in
arch/arm/{mach,plat}-imx/{Kconfig,Makefile}

Pull request had been sent to the wrong email address, but happened
before the merge window closed.  I'm merging the MX 5 consolidation,
since it apparently will help the next development window and will avoid
conflicts later as per Arnd.

Kukjin Kim 830145796a ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

Nicolas Pitre 4702abd3f9 ARM: mach-nuc93x: delete
This architecture received only generic maintenance since December 2009
when it was originally submitted, and no actual additional support since
then.  It has no defconfig entry either, meaning that it was never built
by the ARM KAutobuild.  Incidentally it currently doesn't build either
when CONFIG_MACH_NUC932EVB is selected which is the only possible config
choice.

This is therefore dead code and should be removed.  If someone wants to
revive this code, it could be retrieved from the Git repository, and
ideally be merged in mach-w90x900/ instead.

Stephen Boyd 9e775ad19f ARM: 7012/1: Set proper TEXT_OFFSET for newer MSMs
MSMs post 8x50 have 2Mb at the beginning of RAM reserved for
shared memory. Since the kernel hasn't typically been told this
RAM exists, PHYS_OFFSET has been set to 0xN0200000 and the memory
atags passed to the kernel have matched. This doesn't play nicely
with things such as AUTO_ZRELADDR, which doesn't work at all, and
dynamic phys to virt, which requires an MSM specific workaround.

Work around these issues by telling the kernel RAM starts at
0xN0000000 (it actually does) and fixup the atags from the
bootloader (if necessary) to say the same. In addition, make sure
to set TEXT_OFFSET at least 2Mb beyond the start of RAM so that
the kernel doesn't end up being decompressed into shared memory.

After doing this, AUTO_ZRELADDR should work on MSM with no
problems and ARM_PATCH_PHYS_VIRT_16BIT should no longer be
necessary.

Binghua Duan 02c981c07b ARM: CSR: Adding CSR SiRFprimaII board support
SiRFprimaII is the latest generation application processor from CSR’s
Multifunction SoC product family. Designed around an ARM cortex A9 core,
high-speed memory bus, advanced 3D accelerator and full-HD multi-format
video decoder, SiRFprimaII is able to meet the needs of complicated
applications for modern multifunction devices that require heavy concurrent
applications and fluid user experience. Integrated with GPS baseband,
analog and PMU, this new platform is designed to provide a cost effective
solution for Automotive and Consumer markets.

This patch adds the basic support for this SoC and EVB board based on device
tree. It is following the ZYNQ of Xilinx in some degree.

Wolfram Sang f295dc6874 ARM: mach-stmp378x: remove mach
This mach has not seen any updates since the initial inclusion besides
generic cleanup. Furthermore:

- The i.MX23 covered in mach-mxs is just a renamed version of the
  STMP378x.

- mach-stmp378x has a lot of reinvented interfaces, leaking all sorts of
  mach-related includes into the drivers. One example is the dmaengine
  which does not use the linux dmaengine-API but some privately exported
  symbols. So drivers cannot be reused. mach-mxs does it better.

- There is only one board defined (which I couldn't find any trace of
  despite being a development board). It has been converted to
  mach-mxs in a previous patch.

Since the only user of this mach was converted, it means that
mach-stmp378x can go.

  which does not use the linux dmaengine-API but some privately exported

  does it better.

- It can be doubted that this worked at all. Check the DMA routines in
  stmp37xx.c for copy/paste bugs. A lot of APBX-related stuff is
  actually writing into registers for APBH.

- There is only one board defined (which I couldn't find any trace of
  despite being a development board). In this board, only two devices
  have resources, the debug uart and the application uart. Neither of
  those have the needed custom drivers merged (and never will). debug
  uart is amba-pl011 which has an in-kernel driver without the
  mach-specific-stuff. appuart has a driver which was introduced for
  mach-mxs, and this one is reusable for a properly done mach.

So, this single board registers only unsupported devices and the
generic code looks suspicious and has poor design. Delete this
stuff. If there is interest, it is wiser to restart using
mach-mxs.

Dave Martin 6f685c5cdd ARM: 6781/1: Thumb-2: Work around buggy Thumb-2 short branch relocations in gas
Various binutils versions can resolve Thumb-2 branches to
locally-defined, preemptible global symbols as short-range "b.n"
branch instructions.

This is a problem, because there's no guarantee the final
destination of the symbol, or any candidate locations for a
trampoline, are within range of the branch.  For this reason, the
kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
relocation in modules at all, and it makes little sense to add
support.

The symptom is that the kernel fails with an "unsupported
relocation" error when loading some modules.

Until fixed tools are available, passing
-fno-optimize-sibling-calls to gcc should prevent gcc generating
code which hits this problem, at the cost of a bit of extra runtime
stack usage in some cases.

The problem is described in more detail at:
    https://bugs.launchpad.net/binutils-linaro/+bug/725126

Only Thumb-2 kernels are affected.

This patch adds a new CONFIG_THUMB2_AVOID_R_ARM_THM_JUMP11 config
option which adds -fno-optimize-sibling-calls to CFLAGS_MODULE
when building a Thumb-2 kernel.

Russell King a65d29225e ARM: add 'uinstall' target for installing uboot kernels
We have 'install' and 'zinstall' for installing Image and zImage
kernels, so add 'uinstall' to complete the set.

This allows developers to have a ~/bin/installkernel script which (eg)
copies the kernel to the tftp server automatically once the kernel
has built, resulting in a better workflow.

Pawel Moll dc810efb0c ARM: 6740/1: Place correctly notes section in the linker script
Commit 18991197b4 added --build-id
linker option when toolchain supports it. ARM one does, but for some
reason places the section at 0 when linker script doesn't mention it
explicitly.

The 1e621a8e37 worked around the problem
removing this section from binary image with explicit objcopy options,
but it still exists in vmlinux, confusing tools like debuggers and perf.

This problem was discussed here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html
but the proposed changes to the linker script were substantial.

This patch simply places NOTES (36 bytes long, at least when compiled
with CodeSourcery toolchain) between data and bss, which seem to be
the right place (and suggested by the sample linker script in
include/asm-generic/vmlinux.lds.h).

It is enough to place it correctly in vmlinux (so debuggers are happy):

Section Headers:
  [11] .data             PROGBITS        c07ce000 7ce000 020fc0 00  WA  0   0 32

Section to Segment mapping:
  Segment Sections...
   00     <...> .data .notes .bss
   01     .notes

and to get it exposed as /sys/kernel/notes used by perf tools.

Russell King e399b1a4e1 ARM: v6k: introduce CPU_V6K option
Introduce a CPU_V6K configuration option for platforms to select if they
have a V6K CPU core.  This allows us to identify whether we need to
support ARMv6 CPUs without the V6K SMP extensions at build time.

Currently CPU_V6K is just an alias for CPU_V6, and all places which
reference CPU_V6 are replaced by (CPU_V6 || CPU_V6K).

Select CPU_V6K from platforms which are known to be V6K-only.

Alexey Charkov 21f47fbc5b ARM: 6597/1: Add basic architecture support for VIA/WonderMedia 85xx SoC's
This adds support for the family of Systems-on-Chip produced initially
by VIA and now its subsidiary WonderMedia that have recently become
widespread in lower-end Chinese ARM-based tablets and netbooks.

Support is included for both VT8500 and WM8505, selectable by a
configuration switch at kernel build time.

Included are basic machine initialization files, register and
interrupt definitions, support for the on-chip interrupt controller,
high-precision OS timer, GPIO lines, necessary macros for early debug,
pulse-width-modulated outputs control, as well as platform device
configurations for the specific drivers implemented elsewhere.
