Subject: [PATCH] ARM: efm32: drop selecting NO_DMA
Date: Wed, 24 Sep 2014 20:59:11 +0200 [thread overview]
Message-ID: <1411585151.19525.29.camel@x220> (raw)
The Kconfig entry for ARCH_EFM32 selects NO_DMA. 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.

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?
