How build u-boot that support DDR4 on IMX8MINI

We have a IMX8mini EVK, which is not LPDDR4, but DDR4.

 

For the formal NXP Yocto Linux code:

 

repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.14.98-2.0.0_ga.xml

 

 

I can build the image, which can be run LPDDR4 EVK, but failed to run on DDR4 EVK, as the uboot probably not confied correctly.

 

Now the question is: How can I modify uboot to let it run on DDR4? 

 

I can't find any clue through the doc, and I even can't know where is the uboot code path on Yocto build env, it is so different than the Android build env. It let me feel frustrating.

 

Could someone help me?
