Subject: [PATCH 16/25] MIPS: move coherentio setup to setup.c
Date: Fri, 25 May 2018 11:21:02 +0200	[thread overview]
Message-ID: <20180525092111.18516-17-hch@lst.de> (raw)
In-Reply-To: <20180525092111.18516-1-hch-jcswGhMUV9g@public.gmane.org>

We want to be able to use it even when not building dma-default.c
in the near future.
