Hi Wang

in uboot one can tweak #define PHYS_SDRAM parameter

imx8qxp_mek.h\configs\include - uboot-imx - i.MX U-Boot 

rin ddr test   i.MX 8/8X Family DDR Tools Release  

For scfw  copy the custom DDR CFG file to src/scfw_export_mx8qx_b0/platform/board/mx8qx_mek/dcd and build to the final SCFW. One can try to follow the steps:

1. copy custom CFG file to dcd directory

cp xxx.CFG src/scfw_export_mx8qx_b0/platform/board/mx8qx_mek/dcd

 2. 

make clean

 3.

make qx R=B0 B=mek DDR_CON=xxx

May be recommended first not use OpTee, refer to sect.5.6.10 OP-TEE enablement

i.MX Yocto Project User’s Guide

Best regards
