mpc512x: Streamlined fixed_sdram() init sequence.
Signed-off-by: Martha M Stan <mmarx@silicontkx.com>
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.
