9c261f89a3 ARM: firmware: Introduce suspend and resume operations
This patch extends the firmware_ops structure with two new callbacks:
.suspend() and .resume(). The former is intended to ask the firmware to
save all its volatile state and suspend the system, without returning
back to the kernel in between. The latter is to be called early by
very low level platform suspend code after waking up to restore low
level hardware state, which can't be restored in non-secure mode.

While at it, outdated version of the structure is removed from the
documentation and replaced with a reference to the header file.

836a241832 ARM: expand fixmap region to 3MB
With commit a05e54c103 ("ARM: 8031/2: change fixmap mapping region to
support 32 CPUs"), the fixmap region was expanded to 2MB, but it
precluded any other uses of the fixmap region. In order to support other
uses the fixmap region needs to be expanded beyond 2MB. Fortunately, the
adjacent 1MB range 0xffe00000-0xfff00000 is availabe.

Remove fixmap_page_table ptr and lookup the page table via the virtual
address so that the fixmap region can span more that one pmd. The 2nd
pmd is already created since it is shared with the vector page.

eb785bef68 ARM: SoC DT updates for 3.18
As usual, this is the largest branch, though this time a little under
 half of the total changes with 307 individual non-merge changesets.
 
 The largest changes are the addition of new machines, in particular
 the Tegra based Chromebook, the Renesas r8a7794 SoC, and DT support
 for the old i.MX1 platform.
 
 Other changes include
 - at91: various sam9 and sama5 updates
 - exynos: much extended Peach Pi/Pit (Chromebook 2) support
 - keystone: new peripherals
 - meson: added DT for meson6 SoC
 - mvebu: new device support for Armada 370/375
 - qcom: improved support for IPQ8064 and MSM8x60
 - rockchip: much improved support for rk3288
 - shmobile: lots of updates all over the place

10c8e05620 ARM: SoC driver changes for 3.17
A handful of driver-related changes. We've had a bunch of them going in through
 other branches as well, so it's only a part of what we really have this release.
 
 Larger pieces are:
 
 * Removal of a now unused PWM driver for atmel
   - This includes AVR32 changes that have been appropriately acked.
 * Performance counter support for the arm CCN interconnect
 * OMAP mailbox driver cleanups and consolidation
 * PCI and SATA PHY drivers for SPEAr 13xx platforms
 * Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to
   better model regulators/power.

Marvell has very recently released a public version of the "Functional

Marvell Armada XP SoC. This allows contributors and developers not
under NDA with Marvell to get more details about this SoC than what
the current kernel code shows, and hopefully allows to improve the

Pull ARM updates from Russell King:

 - Major clean-up of the L2 cache support code.  The existing mess was
   becoming rather unmaintainable through all the additions that others
   have done over time.  This turns it into a much nicer structure, and
   implements a few performance improvements as well.

 - Clean up some of the CP15 control register tweaks for alignment
   support, moving some code and data into alignment.c

 - DMA properties for ARM, from Santosh and reviewed by DT people.  This
   adds DT properties to specify bus translations we can't discover
   automatically, and to indicate whether devices are coherent.

 - Hibernation support for ARM

 - Make ftrace work with read-only text in modules

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these
   exceptions.

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.

a05e54c103 ARM: 8031/2: change fixmap mapping region to support 32 CPUs
In 32-bit ARM systems, the fixmap mapping region can support no more
than 14 CPUs(total: 896k; one CPU: 64K). And we can configure NR_CPUS
up to 32. So there is a mismatch.

This patch moves fixmapping region downwards to region 0xffc00000-
0xffe00000. Then the fixmap mapping region can support up to 32 CPUs.

dfd10e7ae6 ARM: SoC platform changes for 3.14
New core SoC-specific changes.
 
 New platforms:
 * Introduction of a vendor, Hisilicon, and one of their SoCs with some
   random numerical product name.
 * Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m, i.e. !MMU).
 * Marvell Berlin series of SoCs, which include the one in Chromecast.
 * MOXA platform support, ARM9-based platform used mostly in industrial products
 * Support for Freescale's i.MX50 SoC.
 
 Other work:
 * Renesas work for new platforms and drivers, and conversion over to
   more multiplatform-friendly device registration schemes.
 * SMP support for Allwinner sunxi platforms.
 * ... plus a bunch of other stuff across various platforms.

83d26d1113 ARM: 7824/1: update advice on kernel, initramfs and FDT load address.
- Recommend that the kernel be placed under 128MiB, this is required if
    CONFIG_AUTO_ZRELADDR=y and good (or at least not bad) advice even if
    CONFIG_AUTO_ZRELADDR=n.
  - Recommend that a zImage kernel be placed above 32MiB, this avoids the need
    to relocate prior to decompression, which can speed up boot.
  - Add basic info on the requirements when loading a raw (non-zImage) kernel
    which are stricter than the zImage requirements.
  - Recommend that the DTB be placed after the 128MiB boundary, avoiding any
    potential conflict with the kernel decompressor, and within the lowmem
    region.  In practice it could follow the kernel loaded after 32MiB,
    assuming the kernel decompesses to less than 32MiB, but the 128MiB
    recommendation is simple and unambiguous.
  - Add similar recommendation regarding initramfs.

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:
 * In Kconfig.debug, various additions trivially conflict,
   the list should be kept in alphabetical order when
   resolving.
