am335x: ddr_defs: Update EMIF parameters EMIF parameters are calculated based on the AC timing parameters from the SDRAM datasheet and the DDR frequency. Current values for these paramters in AM335x U-Boot code, though reliable, are not fully optimal. The most optimal settings can be derived based on the guidelines published at [1]. A pre-computed set of values with the most optimum settings for AM335x EVM and BeagleBone can be found at [2].
