bd84dff021 ARM: oxnas: make ox820_boot_secondary static
Fix sparse warning:

arch/arm/mach-oxnas/platsmp.c:30:12: warning: symbol 'ox820_boot_secondary' was
not declared. Should it be static?

0eb037998a ARM: oxnas: remove CPU hotplug implementation
The CPU hotplug implementation on this platform is cargo-culted from
the plat-versatile implementation, and is buggy.  Once a CPU hits the
"low power" loop, it will wait for pen_release to be set to the CPU
number to wake up again - but nothing in this implementation does that.

So, once a CPU has entered cpu_die() it will never, ever leave.

Remove this useless cargo-culted implementation.

af76e806b5 ARM: oxnas: Add OX820 SMP support
The Oxford Semiconductor OX820 is a ARM11MPcore based SoC sharing some
features with the OX810 earlier SoC.
This patch adds the core to wake up the second core.

Clarifications about Copyrights dates :
- hotplug.c was taken from an old versatile code by Ma Haijun and left verbatim
- headsmp.S was taken from an old versatile code and adapted by Ma Haijun
- platsmp.c is a mix from versatile code, Ma Haijun code and my code for DT
Hence the 2002/2003 ARM Coryrights and 2013 Ma Haijun Copyrights.

af9d238c6a ARM: oxnas: select reset controller framework
For unknown reasons, we have to enable three symbols for a platform
to use a reset controller driver, otherwise we get a Kconfig
warning:

warning: (MACH_OX810SE) selects RESET_OXNAS which has unmet direct dependencies (RESET_CONTROLLER)

This selects the other two symbols for oxnas.

7c2d780ec0 Merge ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB changes into next/soc
* commit '5c34a4e89c743339f78cafb2f2a826a010f0746a':
  ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
  ARM: uniphier: drop code for old DT binding

These cause a harmless conflict with the clps711x multiplatform
support, and it's easy to resolve.

5c34a4e89c ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".
