From 05b75e48832fc4afeecf8e76d704349557dffa35 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 6 Oct 2008 03:35:44 -0400 Subject: Blackfin: fix dcache handling when doing dma memcpy's Our dcache invalidate function doesn't just invalidate, it also flushes. So rename the function accordingly and fix the dma_memcpy() function so it doesn't inadvertently corrupt the data destination.
