Subject: [PATCH 8/9] MIPS: Add a platform hook for swiotlb setup.
Date: Thu, 23 Sep 2010 15:38:15 -0700 [thread overview]
Message-ID: <1285281496-24696-9-git-send-email-ddaney@caviumnetworks.com> (raw)
In-Reply-To: <1285281496-24696-1-git-send-email-ddaney@caviumnetworks.com>
This allows platforms that are using the swiotlb to initialize it.
