From bdef2fe88b1e4bde7458aedd207929ce3f9d66ee Mon Sep 17 00:00:00 2001 From: Nicolas Ferre <nicolas.ferre@atmel.com> Date: Sat, 15 May 2010 12:32:31 -0400 Subject: [PATCH] mmc: at91_mci: modify cache flush routines As we were using an internal dma flushing routine, this patch changes to the DMA API flush_kernel_dcache_page(). Driver is able to compile now.
