From 634286f127bef8799cd04799d3e1d5471e8fd91c Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 28 Jan 2009 17:48:40 +0000 Subject: [PATCH] MIPS: IP27: Switch from DMA_IP27 to DMA_COHERENT The special IP27 DMA code selected by DMA_IP27 has been removed a while ago turning DMA_IP27 into almost a nop. Also fixup the broken logic of its last users memcpy.S and memcpy-inatomic.s.
