Hi, I did not test myself the SPL for any 9x5 board. The DDR2 init code should be executed inside the SPL. Once you build your board with a CONFIG_SPL enabled, you should get the spl binary built, then you can add both SPL + U-boot proper on the boot media and have SPL boot (execute DDR init code and load U-boot proper). I would suggest to try on Sd-card first because it's easier (filesystem), but the commit says only SPI and NAND tested. You can also look at the U-boot version which first included this patch, some things may have changed since... Let me know of your findings. I will let you know if I have the chance to test this myself.
