IMX6 DDR Frequency change with newer u-boot

I built a custom image from the latest sources for the imx6q-sabresd board.  The image works fine but I'd like to change the u-boot to initialize the dram to a slower speed so we can test if our software will continue to perform properly.  There are a number of posts with this same question but the version of u-boot seems to be quite a bit different.  I'm using 2018.17.  The older posts refer to flash_header.S or a various DTC table versions which don't seem to have changed in the latest version.  Either that or I just don't know where to look which could also be the case.


Anyhow, anyone have a quick pointer to the right sources to start looking at?
