i use IMX6D linux3.10.53

now i want to chang the DDR frequency from 528MHZ to 400MHZ,
First i change 528 to 400 in I.MX6DQSDL DDR3 Script Aid V0.10,and then i use this config to calibration config to do the DDR calibration , and i also have put these configs and it's calibration result to the DCD files in uboot.
Except these, need i to modify other code of kernel or uboot for changing  DDR frequency from 528MHZ to 400MHZ?
