From 3ed167af96ed098187ea41353fe02d1af20d38a1 Mon Sep 17 00:00:00 2001 From: Kristoffer Ericson Date: Tue, 16 Jun 2009 15:34:40 -0700 Subject: [PATCH] fbdev: s1d13xxxfb: add accelerated bitblt functions Add accelerated bitblt functions to s1d13xxx based video chipsets, more specificly functions copyarea and fillrect. It has only been tested and activated for 13506 chipsets but is expected to work for the majority of s1d13xxx based chips. This patch also cleans up the driver with respect of whitespaces and other formatting issues. We update the current status comments.
