2016-06-03ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIBLinus Walleij
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".

2015-12-01ARM: use "depends on" for SoC configs instead of "if" after promptMasahiro Yamada
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).

2015-02-23ARM: sunxi: Have ARCH_SUNXI select RESET_CONTROLLER for clock driver usageChen-Yu Tsai
As the sunxi usb clocks all contain a reset controller, it is not possible to build the sunxi clock driver without RESET_CONTROLLER enabled. Doing so results in an undefined symbol error: drivers/built-in.o: In function `sunxi_gates_clk_setup': linux/drivers/clk/sunxi/clk-sunxi.c:1071: undefined reference to `reset_controller_register' This is possible if building a minimal kernel without PHY_SUN4I_USB. The dependency issue is made visible at compile time instead of link time by the new A80 mmc clocks, which also use a reset control itself. This patch makes ARCH_SUNXI select ARCH_HAS_RESET_CONTROLLER and RESET_CONTROLLER.

2014-05-26ARM: sunxi: allow building without reset controllerArnd Bergmann
The sunxi reset controller code is only used with sun6i (a31). After the platform has been split up into per-soc options, it's now possible to build it without the reset controller code, so the base platform init must not call into the reset driver if that is turned off at compile time.

2014-05-23ARM: sunxi: Remove init_machine callbackMaxime Ripard
The init_machine hook is now at its default value. We can remove it. Even though the sun4i and sun7i machines are nothing more than generic machines now, leave them in so that we won't have to add them back if needed, and so that the machine is still displayed in /proc/cpuinfo.

2014-05-23ARM: sunxi: Remove reset code from the platformMaxime Ripard
Now that reset is handled either by the watchdog driver for the sun4i, sun5i and sun7i, and by a driver of its own for sun6i, we can remove it from the platform code. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

Now that we can rely on the enable-method, remove the smp field declaration from A31 machine. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2014-05-17ARM: sun6i: Use CPU_METHOD_OF_DECLAREMaxime Ripard
CPU_METHOD_OF_DECLARE allows to bind the smp_ops to a set of cpus through the enable-method property, instead of relying on the machine to define it. Switch to it to get closer to an empty machine. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

Building an SMP kernel for the sunxi platform with THUMB2 instructions fails with this error at the moment: headsmp.S:7: Error: Thumb encoding does not support an immediate here -- `msr cpsr_fsxc,#0xd3' Since the generic secondary_startup function already does the same thing in a safe way, we can just drop the private sunxi implementation and jump straight to secondary_startup.
