Was this patch made against the current u-boot-ti/next.
The reason I say this is because there was a DDR patch that affects all OMAP3 boards. So this support should be added against u-boot-ti/next and tested against it. I believe there is a config option to choose between MICRON and INFINEON DDR's.
