From ec3cf2ece22a8ede7478bf38e2a818986322662b Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Thu, 14 May 2009 12:42:28 +0000 Subject: powerpc: Add support for swiotlb on 32-bit This patch includes the basic infrastructure to use swiotlb bounce buffering on 32-bit powerpc. It is not yet enabled on any platforms. Probably the most interesting bit is the addition of addr_needs_map to dma_ops - we need this as a dma_op because the decision of whether or not an addr can be mapped by a device is device-specific.
