f327d43da1 ARM: mvebu: use GIC_{SPI,PPI} in Armada 375/38x DTs
Instead of hardcoding 0 and 1 to indicate SPI and PPI GIC interrupts,
use the definitions of <dt-bindings/interrupt-controller/arm-gic.h> to
clarify the Device Tree code.

a2be1561a3 ARM: mvebu: use C preprocessor include for Armada 375/38x DTs
Some of the Armada 375/38x DTs that were recently submitted were still
using the old-style /include/ instead of the new-style, C-preprocessor
based #include. Since we are going to start including more headers,
switching to the C-preprocessor based includes is important.

868eb61602 watchdog: orion: Make RSTOUT register a separate resource
In order to support other SoC, it's required to distinguish
the 'control' timer register, from the 'rstout' register
that enables system reset on watchdog expiration.

To prevent a compatibility break, this commit adds a fallback
to a hardcoded RSTOUT address.

2d0a7addbd ARM: Kirkwood: Add support for many Synology NAS devices
Add device tree fragments and files to support many of the kirkwood
based Synology NAS devices. This is a modification of
Andrew Lunn's <andrew@lunn.ch> translation of the board setup file
maintained by Ben Peddell <klightspeed@killerwolves.net>

The Ricoh RS5C372 RTC was used in all 2009 units and some 2010 units.
All other Synology Kirkwood-based DiskStations and RackStations use
the Seiko S35390A RTC.

Most of the 1-bay and 2-bay units use the GPIOs that are multiplexed
with the built-in SATA interface activity/presence pins on mpp 20-23,
while the 4-bay units use ge01 and a PCIe SATA controller, and put the
software controlled HDD leds on mpp 36-43.

Most of the 6281 units with HDD power controls use mpp 29 and 31, while
most of the 6282 units with HDD power controls use mpp 30, 34, 44 and 45
and provide a model ID on mpp 28, 29, 46 and 47.  Pre-2012 units and
most 4-bay units didn't have a separate power control for HDD1.  These
power controls are presumably to limit startup current from the 12V
brick power supply.

Instead of using separate dtsi files in a synology directory, this
patch uses a single dtsi file containing all of the modules for
these boards, with all of the modules not common to all boards
disabled.  The board dts files then enable the appropriate modules for
their boards.

9aa30f1c13 ARM: mvebu: add initial support for the Armada 380/385 SOCs
This commit adds the basic support for the Armada 380 and Armada 385
SOCs. These SoCs share most of their IP with the Armada 370/XP
SoCs. The main difference is the use of a Cortex A9 CPU instead of the
PJ4B CPU. The Armada 380 is a single core Cortex-A9, while the Armada
385 is a dual-core Cortex-A9.

The support is introduced in board-v7.c, together with Armada 370/XP,
but a separate DT structure is added, because Armada 38x will need a
different set of SMP operations when the SMP support is introduced.

ca4a6f8715 ARM: mvebu: add workaround for data abort issue on Armada 375
Early versions of Armada 375 SoC have a bug where the BootROM leaves
an external data abort pending. The kernel is hit by this data abort
as soon as it enters userspace, because it unmasks the data aborts at
this moment. We register a custom abort handler below to ignore the
first data abort to work around this problem.

99b3d29462 ARM: mvebu: rename armada-370-xp.c to board-v7.c
In preparation to the introduction of the support of Armada 375 and
Armada 38x, this commit renames arch/arm/mach-mvebu/armada-370-xp.c to
arch/arm/mach-mvebu/board-v7.c. The board-v7.c name as we expect this
file to ultimately contain the DT_MACHINE_START definitions for all
ARMv7 Marvell EBU platforms (370, 375, 38x, XP and Dove as of today).

In relation to this file rename, this commit also:

 * Renames the hidden Kconfig symbol MACH_ARMADA_370_XP to
   MACH_MVEBU_V7. This hidden symbol is selected by the various
   per-SoC visible Kconfig options to trigger the build of board-v7.c.

 * Renames a certain number of functions in board-v7.c so that their
   armada_370_xp prefix is replaced by a mvebu prefix. The .dt_compat
   array keeps its armada_370_xp prefix because the new SOCs will be
   introduced with separate .dt_compat arrays, due to the need for
   different SMP operations.

  This branch contains a bug fix for the way devicetree code identifies

  of_device_ids, but it more than one entry will match, then the device
  driver may choose the wrong one.  Commit 105353145e, "match each node

  ended up causing other bugs.  Commit 06b29e76a7 attempted to fix it
  but it had other bugs.  Merely reverting the fix and waiting until
  v3.15 isn't a good option because there is code in v3.14 that depends
  on the revised behaviour to boot.

  This branch should finally fixes the problem correctly.  This time
  instead of just hoping that the patch is correct, this branch also
  adds new testcases that validate the behaviour.

b363457593 ARM: 7980/1: kernel: improve error message when LPAE config doesn't match CPU
Currently, when the kernel is configured with LPAE support, but the
CPU doesn't support it, the error message is fairly cryptic:

  Error: unrecognized/unsupported processor variant (0x561f5811).

This messages is normally shown when there is an issue when comparing
the processor ID (CP15 0, c0, c0) with the values/masks described in
proc-v7.S. However, the same message is displayed when LPAE support is
enabled in the kernel configuration, but not available in the CPU,
after looking at ID_MMFR0 (CP15 0, c0, c1, 4). Having the same error
message is highly misleading.

This commit improves this by showing a different error message when
this situation occurs:

  Error: Kernel with LPAE support, but CPU does not support LPAE.

either from DT or by probing a CPU it is running on. For

this probing won't work well for big.LITTLE systems with heterogeneous
PMUs.

This patch drops the probing for those CPUs, relying on information from
dt instead. Future platforms should describe their PMU(s) with dt.

b7aafe9928 ARM: perf: fully support Krait CPU PMU events
Krait supports a set of performance monitor region event
selection registers (PMRESR) sitting behind a cp15 based
interface that extend the architected PMU events to include Krait
CPU and Venum VFP specific events. To use these events the user
is expected to program the region register (PMRESRn) with the
event code shifted into the group they care about and then point
the PMNx event at that region+group combo by writing a
PMRESRn_GROUPx event. Add support for this hardware.

Note: the raw event number is a pure software construct that
allows us to map the multi-dimensional number space of regions,
groups, and event codes into a flat event number space suitable
for use by the perf framework.

This is based on code originally written by Ashwin Chaugule and
Neil Leeder [1].

eab443ef39 ARM: perf: add hook for event index clearing
On Krait processors we have a many-to-one relationship between
raw CPU events and the event programmed into the PMNx counter.
Two raw CPU events could map to the same value programmed in the
PMNx counter. To avoid this problem, we check for collisions
during the get_event_idx() callback by setting a bit in a bitmap
whenever a certain event is used in a PMNx counter (see the next
patch). Unfortunately, we don't have a hook to clear this bit in
the bitmap when the event is deleted so let's add an optional
clear_event_idx() callback for this purpose.

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

c8a4c63f8c ARM: mvebu: Allows to get the SoC ID even without PCI enabled
The address translation of a PCI node don't require anymore the PCI
support in the kernel. This translation is mandatory to be able to
read the SoC ID which is stored in the PCI controller of the mvebu
SoCs.

This patch selects the symbol needed to get only this translation for
all the mvebu platforms.

b5190516b2 of: Move testcase FDT data into drivers/of
The testcase data is usable by any platform. This patch moves it into
the drivers/of directory so it can be included by any architecture.

Using the test cases requires manually adding #include <testcases.dtsi>
to the end of the boards .dtsi file and enabling CONFIG_OF_SELFTEST. Not
pretty though. A useful project would be to make the testcase code
easier to execute.
