Dear all,
the following series fixes a couple of issues on the i.MX6 DDR3 memory
initialization we discovered while debugging some rare boot failures on
apalis-imx6 [0]. This is a follow-up of this RFC series [1], with the
apalis-imx6 changes removed since we do plan doing additional validation before
merging.
