Pull ARM SoC cleanups from Olof Johansson:
 "The cleanup branch keeps going down in size as we've completed a lot
  of the major legacy platform removals and conversions.

  A handful of changes this time around, some of the themes or larger
  sets are:

   - A bunch of i.MX cleanups around platform detection, init call cleanups
   - Misc fixes of missing/implicit includes
   - Removal of ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"

clocksource/drivers/prima2: Add the COMPILE_TEST option

2016-06-28T08:22:12+00:00

Change the Kconfig option logic to fullfil with the current approach.

A new Kconfig option is added, CONFIG_PRIMA2_TIMER and is selected by the
platform. Then the clocksource's Kconfig is changed to make this option
selectable by the user if the COMPILE_TEST option is set. Otherwise, it is
up to the platform's Kconfig to select the timer.

ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

2016-06-03T19:18:13+00:00

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".

Pull ARM SoC cleanups from Arnd Bergmann:
 "A few simple cleanups across multiple platforms, not much standing
  out:

   - lpc32xx removes its private implementation of the clk API, after
     generic code was merged in 4.5
   - all unused Makefile.boot files get removed
   - a number of simplifications for shmobile
   - asm/clkdev.h gets replaced with the asm-generic version after all
     mach/clkdev.h implementations are gone"

ARM: prima2: always enable reset controller

2016-02-26T16:46:29+00:00

The atlas7 clock controller driver registers a reset controller
for itself, which causes a link error when the subsystem is
disabled:

drivers/built-in.o: In function `atlas7_clk_init':
drivers/clk/sirf/clk-atlas7.c:1681: undefined reference to `reset_controller_register'

As the clk driver does not have a Kconfig symbol for itself
but it always built-in when the platform is enabled, we have
to ensure that the reset controller subsystem is also built-in
in this case.

ARM: drop unused Makefile.boot of Multiplatform SoCs

2016-02-08T21:35:41+00:00

The variable "MACHINE" is empty if CONFIG_ARCH_MULTIPLATFORM=y,
so these Makefile.boot files are never included.

ARM: use "depends on" for SoC configs instead of "if" after prompt

2015-12-01T21:44:51+00:00

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.

Please notice the difference between

    config ARCH_FOO
            bool "Foo SoCs" if ARCH_MULTI_V7

and

    config ARCH_FOO
            bool "Foo SoCs"
            depends on ARCH_MULTI_V7

These two are *not* equivalent!

In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7.  So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns.  This is probably not what
you want.

The former should be used only when you need to do so, and you really
understand what you are doing.  (In most cases, it should be wrong!)

For enabling/disabling sub-architectures, the latter is always correct.

As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).

[Arnd: I note that there is not really a bug here, according to
 the discussion that followed, but I can see value in being consistent
 and in making the lines shorter]

ARM: use const and __initconst for smp_operations

2015-12-01T21:17:45+00:00

These smp_operations structures are not over-written, so add "const"
qualifier and replace __initdata with __initconst.

Also, add "static" where it is possible.

ARM: Remove __ref on hotplug cpu die path

2015-10-22T16:55:03+00:00

Now that __cpuinit has been removed, the __ref markings on these
functions are useless. Remove them. This also reduces the size of
the multi_v7_defconfig image:

$ size before after
   text    data     bss     dec     hex filename
   12683578        1470996  348904 14503478         dd4e36 before
   12683274        1470996  348904 14503174         dd4d06 after

presumably because now we don't have to jump to code in the
.ref.text section and/or the noinline marking is removed.
