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).

Say Y here if you want to run your kernel on hardware with a
MOXA ART SoC.
The MOXA ART SoC is based on a Faraday FA526 ARMv4 32-bit
192 MHz CPU with MMU and 16KB/8KB D/I-cache (UC-7112-LX).
Used on models UC-7101, UC-7112/UC-7110, IA240/IA241, IA3341.
if ARCH_MOXART
config MACH_UC7112LX
bool "MOXA UC-7112-LX"
depends on ARCH_MOXART
help
Say Y here if you intend to run this kernel on a MOXA
UC-7112-LX embedded computer.
