From: Ludwig Zenz lzenz@dh-electronics.de The four x16 DDR3 are wired in T-topology. From NXP AN4467: 'Although not required, T-Topologies may also benefit from performing Write Leveling as there are package delays on both the processor and DDR devices that can be de-skewed by performing Write Leveling. Therefore, Freescale recommends determining Write Leveling calibration parameters for all boards, regardless of topology used.' That is why write level calibration is also done.

Applied to u-boot-imx, master, thanks !
