Subject: [PATCH 07/20] nds32/io: Remove useless definition of mmiowb()
Date: Fri, 1 Mar 2019 14:03:35 +0000 [thread overview]
Message-ID: <20190301140348.25175-8-will.deacon@arm.com> (raw)
In-Reply-To: <20190301140348.25175-1-will.deacon@arm.com>
mmiowb() only makes sense for SMP platforms, so we can remove it
entirely for nds32.
