From 054197ba8ee5ef1e41694df58531b6e53ec43f2d Mon Sep 17 00:00:00 2001 From: Martha M Stan Date: Mon, 21 Sep 2009 14:07:14 -0400 Subject: mpc512x: Streamlined fixed_sdram() init sequence. Signed-off-by: Martha M Stan Minor cleanup: Re-ordered default_mddrc_config[] to have matching indices. This allows to use the same index "N" for source and target fields; before, we had code like this out_be32(&im->mddrc.ddr_time_config2, mddrc_config[3]); which always looked like a copy & paste error because 2 != 3. Also, use NULL when meaning a null pointer.
