2015-12-02ARM: use "depends on" for SoC configs instead of "if" after promptMasahiro Yamada1-4/+8
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).

2015-06-01ARM: v7 setup function should invalidate L1 cacheRussell King4-20/+3
All ARMv5 and older CPUs invalidate their caches in the early assembly setup function, prior to enabling the MMU. This is because the L1 cache should not contain any data relevant to the execution of the kernel at this point; all data should have been flushed out to memory. This requirement should also be true for ARMv6 and ARMv7 CPUs - indeed, these typically do not search their caches when caching is disabled (as it needs to be when the MMU is disabled) so this change should be safe. ARMv7 allows there to be CPUs which search their caches while caching is disabled, and it's permitted that the cache is uninitialised at boot; for these, the architecture reference manual requires that an implementation specific code sequence is used immediately after reset to ensure that the cache is placed into a sane state. Such functionality is definitely outside the remit of the Linux kernel, and must be done by the SoC's firmware before _any_ CPU gets to the Linux kernel. Changing the data cache clean+invalidate to a mere invalidate allows us to get rid of a lot of platform specific hacks around this issue for their secondary CPU bringup paths - some of which were buggy.

2015-05-06ARM: hisi/hip04: remove the MCPM overheadNicolas Pitre1-85/+42
This platform is currently relying on the MCPM infrastructure for no apparent reason. The MCPM concurrency handling brings no benefits here as there is no asynchronous CPU wake-ups to be concerned about (this is used for CPU hotplug and secondary boot only, not for CPU idle). This platform is also different from the other MCPM users because a given CPU can't shut itself down completely without the assistance of another CPU. This is at odds with the on-going MCPM backend refactoring. To simplify things, this is converted to hook directly into the smp_operations callbacks, bypassing the MCPM infrastructure.

2015-02-19ARM: make arrays containing machine compatible strings constUwe Kleine-König1-4/+4
The definition static const char *axxia_dt_match[] __initconst = { ... defines a changable array of constant strings. That is you must not do: *axxia_dt_match[0] = 'k'; but axxia_dt_match[0] = "different string"; is fine. So the annotation __initconst is wrong and yields a compiler error when other really const variables are added with __initconst. As the struct machine_desc member dt_compat is declared as const char *const *dt_compat; making the arrays const is the better alternative over changing all annotations to __initdata.

hisi has a general dependency on ARCH_MULTIPLATFORM, which is problematic when building a kernel for non-V7 platforms but selecting drivers that might conflict with other architecture levels. In this case, it broke my (still out of tree) patch set that enables V7M multiplatform support, since that does not enable MULTI_IRQ support: arch/arm/kernel/built-in.o: In function `set_handle_irq': arch/arm/kernel/irq.c:125: undefined reference to `handle_arch_irq' arch/arm/kernel/built-in.o: In function `setup_arch': arch/arm/kernel/setup.c:965: undefined reference to `handle_arch_irq' Since all hisilicon platforms are ARMv7 based, we can avoid this problem by just making the dependency more specific.

2014-03-21ARM: hisi: fix building without CONFIG_HOTPLUG_CPUArnd Bergmann2-2/+3
The hisi SMP code always uses the hi3xxx_set_cpu() function defined in the hotplug.c file, so we cannot build without this when CONFIG_SMP is enabled. This patch slightly restructures the code so we always build the parts of hotplug.c that we need but just leave out the CPU disable logic if CONFIG_HOTPLUG_CPU is turned off.

2014-02-20ARM: centralize common multi-platform kconfig optionsRob Herring1-3/+0
Multi-platform requires various kconfig options to be selected, so platforms don't need to select them individually.

Since init_time in machine descriptor is already covered by arch/arm/kernel/time.c by default. We needn't to append it any more. Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com> Signed-off-by: Kevin Hilman <khilman@linaro.org>
2013-12-20ARM: hisi: rename hi3xxx to hisiHaojian Zhuang6-0/+425
Since some new Hisilicon SoCs are not named as hi3xxx, rename mach-hi3xxx to mach-hisi instead. And the pronounciation of "hisi" is similar to the chinese pronounciation of Hisilicon. So Hisilicon guys like this name. ARCH_HI3xxx will be renamed later since other drivers are using it and they are still in linux-next git tree. So rename ARCH_HI3xxx later.
