Selecting user-visible symbols is rather discouraged so why not something like this: - def_bool y if ARCH_EXYNOS - depends on !ARM64 + bool "Exynos multi core timer driver" + depends on ARCH_EXYNOS || (COMPILE_TEST && ARM) Best regards, Krzysztof > > Add the COMPILE_TEST option for the compilation test coverage.
