e8a0b37d28 Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
 "Bigger items included in this update are:

   - A series of updates from Arnd for ARM randconfig build failures
   - Updates from Dmitry for StrongARM SA-1100 to move IRQ handling to
     drivers/irqchip/
   - Move ARMs SP804 timer to drivers/clocksource/
   - Perf updates from Mark Rutland in preparation to move the ARM perf
     code into drivers/ so it can be shared with ARM64.
   - MCPM updates from Nicolas
   - Add support for taking platform serial number from DT
   - Re-implement Keystone2 physical address space switch to conform to
     architecture requirements
   - Clean up ARMv7 LPAE code, which goes in hand with the Keystone2
     changes.
   - L2C cleanups to avoid unlocking caches if we're prevented by the
     secure support to unlock.
   - Avoid cleaning a potentially dirty cache containing stale data on
     CPU initialisation
   - Add ARM-only entry point for secondary startup (for machines that
     can only call into a Thumb kernel in ARM mode).  Same thing is also
     done for the resume entry point.
   - Provide arch_irqs_disabled via asm-generic
   - Enlarge ARMv7M vector table
   - Always use BFD linker for VDSO, as gold doesn't accept some of the
     options we need.
   - Fix an incorrect BSYM (for Thumb symbols) usage, and convert all
     BSYM compiler macros to a "badr" (for branch address).
   - Shut up compiler warnings provoked by our cmpxchg() implementation.
   - Ensure bad xchg sizes fail to link"

3e0d0b81ea The i.MX SoC updates for 4.2:
- Add new SoC i.MX7D support, which integrates two Cortex-A7 and one
    Cortex-M4 cores.
  - Support suspend from IRAM on i.MX53, so that DDR pins can be set to
    high impedance for more power saving during suspend.
  - Move i.MX clock drivers from arch/arm/mach-imx to drivers/clk/imx.
  - Move i.MX GPT timer driver from arch/arm/mach-imx into
    drivers/clocksource.
  - A couple of clock driver update for VF610 and i.MX6Q.
  - A few random code correction and improvement.

499f164020 ARM: use ARM_SINGLE_ARMV7M for ARMv7-M platforms
Use the new config symbol ARM_SINGLE_ARMV7M which groups config
symbols used by modern ARMv7-M platforms. This allows supporting
multiple ARMv7-M platforms in one kernel image. However, a common
kernel image requires the combined platforms to share the same
main memory layout to be bootable.

9c77bc438f ARM: introduce ARM_SINGLE_ARMV7M for ARMv7-M platforms
This introduces a new top level config symbol ARM_SINGLE_ARMV7M
for non-MMU, ARMv7-M platforms. It also support multiple ARMv7-M
platforms in one kernel image since the cores share the same
basic memory layout and interrupt controller. However, this works
only if the combined platforms also have a similar (main) memory
layout.

Add support for NXP's LPC18xx (Cortex-M3) and LPC43xx (Cortex-M4)
SoCs. These SoCs are NXP's high preformance MCU line and can run at
clock speeds up to 180 MHz for LPC18xx and 204 MHz for LPC43xx.

LPC43xx is more or less a LPC18xx with a Cortex-M4F core and a few
extra peripherals. The LPC43xx series also features one or two
Cortex-M0 cores that can be used to offload the main M4 core.

e5ac320de1 ARM: SoC multiplatform code changes for v4.1
The changes here belong to two main platforms:
 
 - Atmel At91 is flipping the bit and going multiplatform. This includes some
   cleanups and removal of code, and the final flip of config dependencies
 
 - Shmobile has several platforms that are going multiplatform, but this
   branch also contains a bunch of cleanups that they weren't able to keep
   separate in a good way. THere's also a removal of one of their SoCs and the
   corresponding boards (sh7372 and mackerel).

 - A rework greatly simplifying adding new platform support to the MCPM

 - Cpuidle and PM improvements for Exynos3250
 - Misc updates for Renesas, OMAP, Meson, i.MX. Some of these could have
   gone in other branches but ended up here for various reasons.

 - OMAP removes legacy board files for three more platforms
 - Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom
 - Freescale i.MX25 also removes non-DT platform support

01081f5ab9 coresight: moving to new "hwtracing" directory
Keeping drivers related to HW tracing on ARM, i.e coresight,
under "drivers/coresight" doesn't make sense when other
architectures start rolling out technologies of the same
nature.

As such creating a new "drivers/hwtracing" directory where all
drivers of the same kind can reside, reducing namespace
pollution under "drivers/".

[arnd: The sh7372 platform is rather dated and is believed to

 of converting all of mach-shmobile to be multiplatform capable,
 as adding pinctrl and common-clock support for it would be more
 work than it's  worth. As always, should any legitimate upstream
 users show up in the future, we will revert this removal]

Remove support for the legacy Cortex-A8 based sh7372 SoC.

The Linux kernel still lacks DT bindings for the sh7372 INTC
interrupt controller so DT multiplatform support is not possibile.

Also, the sh7372 SoC never went into mass production anyway so to
aid migration to DT multiplatform simply get rid of sh7372 support.

878ba61aa9 ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

a61cbf51f0 ARM: 8274/1: Fix DEBUG_LL for multi-platform kernels (without PL01X)
When building a multi_v7_defconfig kernel it is not possible to configure
DEBUG_LL to use any serial device except a ARM Primecell PL01X, or more
accurately and worse, it is possible to configure a different serial
device but KConfig does not honour this request. In fact this also
overrides the user selection for some of the single platform kernels, for
example I don't think DEBUG_LL can be targeted at ICE or semihosted
supervisor for ARCH_VERSATILE.

This happens because DEBUG_UART_PL01X is automatically enabled by
some architectures and this means user decisions made regarding
the DEBUG_LL backend will be overridden. Problem is fixed by removing the
automatic enabling of this option.

d02fde7fc0 ARM: 8273/1: Seperate DEBUG_UART_PHYS from DEBUG_LL on EP93XX
On EP93XX uncompress.h uses CONFIG_DEBUG_UART_PHYS instead of a hard
coded serial port. This means the build breaks when DEBUG_LL
(and DEBUG_LL_UART_PL01X) is not enabled.

This is fixed by adding a new dependency.

c26b999353 ARM: 8271/1: omap1: Migrate debug_ll macros to use 8250.S
The omap1's debug-macro.S is similar to the generic 8250 code. Compared to
the 8520 code the omap1 macro automatically determines what UART to use
based on breadcrumbs left by the bootloader and automatically copes with
the eccentric register layout on OMAP7XX.

This patch drops both these features and relies instead on the generic
8250 macros:

1. Dropping support for the bootloader breadcrumbs is identical to the
   way the migration was handled for OMAP2 (see 808b7e07464d...).

2. Support for OMAP7XX still exists but it must be configured by hand
   (DEBUG_OMAP7XXUART1/2/3) rather than handled at runtime.

        initial pxa27x DT handling
   - rockchip:
        SMP support for rk3288
        add cpu frequency scaling support
   - shmobile:
        r8a7740 power domain support
        various small restart, timer, pci apmu changes
   - sunxi:
        Allwinner A80 (sun9i) earlyprintk support
   - ux500:
        power domain support

  Overall, a significant chunk of changes, coming mostly from the usual
  suspects: omap, shmobile, samsung and mvebu, all of which already
  contain a lot of platform specific code in arch/arm"
