From dcfec3c09890120d86d4e86887074c76763075ca Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 20 Aug 2013 10:04:32 +0200 Subject: dma: imx-sdma: Add ROM script addresses to driver This adds the ROM script addresses for i.MX25, i.MX5x and i.MX6 to the SDMA driver needed for the driver to work without additional firmware. The ROM script addresses are SoC specific and in some cases even tapeout specific. This patch adds the ROM script addresses only for SoCs which do not have a tapeout specific SDMA ROM, because currently it's unclear how this case should be handled.
