From e324654294907a420ab3773efe8849a935f37bf0 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 16 Nov 2015 12:06:10 +0900 Subject: ARM: use "depends on" for SoC configs instead of "if" after prompt 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] Signed-off-by: Masahiro Yamada Acked-by: Maxime Ripard Acked-by: Nicolas Ferre Acked-by: Heiko Stuebner Acked-by: Patrice Chotard Acked-by: Liviu Dudau Acked-by: Krzysztof Kozlowski Acked-by: Jun Nie Acked-by: Matthias Brugger Acked-by: Simon Horman Acked-by: Gregory CLEMENT Acked-by: Shawn Guo Acked-by: Sebastian Hesselbarth Acked-by: Thierry Reding Acked-by: Krzysztof Halasa Acked-by: Maxime Coquelin Signed-off-by: Arnd Bergmann --- arch/arm/mach-shmobile/Kconfig | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/arm/mach-shmobile/Kconfig') diff --git a/arch/arm/mach-shmobile/Kconfig b/arch/arm/mach-shmobile/Kconfig index 88734a5e10ca..0f25f8fa2692 100644 --- a/arch/arm/mach-shmobile/Kconfig +++ b/arch/arm/mach-shmobile/Kconfig @@ -30,8 +30,8 @@ config ARCH_RMOBILE select SYS_SUPPORTS_SH_TMU menuconfig ARCH_SHMOBILE_MULTI - bool "Renesas ARM SoCs" if ARCH_MULTI_V7 - depends on MMU + bool "Renesas ARM SoCs" + depends on ARCH_MULTI_V7 && MMU select ARCH_SHMOBILE select HAVE_ARM_SCU if SMP select HAVE_ARM_TWD if SMP -- cgit
