Subject: [PATCH 23/28] mpc82xx: Define CPU_FTR_NEED_COHERENT
Date: Mon, 17 Sep 2007 11:58:15 -0500 [thread overview]
Message-ID: <20070917165815.GW6563@loki.buserror.net> (raw)
In-Reply-To: <20070917165643.GA6545@loki.buserror.net>
The 8272 (and presumably other PCI PQ2 chips) appear to have the
same issue as the 83xx regarding PCI streaming DMA.
