But that doesn't have any effect as arm doesn't have a Kconfig entry for NO_DMA. This select is a nop. Drop it. Signed-off-by: Paul Bolle Acked-by: Uwe Kleine-König --- Tested by playing with arch/arm/configs/efm32_defconfig. After "make oldconfig" the .config contains CONFIG_HAS_DMA=y both before and after this patch, as is expected. Actually, the only difference I found in the .config file was that after this patch the .config file contained CONFIG_ARCH_EFM32=y I have no idea why. Did I botch my test? arch/arm/Kconfig | 1 - 1 file changed, 1 deletion(-) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index d63e50615e9c..804ddc134c3c 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -426,7 +426,6 @@ config ARCH_EFM32 select COMMON_CLK select CPU_V7M select GENERIC_CLOCKEVENTS - select NO_DMA select NO_IOPORT_MAP select SPARSE_IRQ select USE_OF
