whether uboot support 16bit DDR configuration

Dear TI

sdk version:sdk6.0

I have used the EMIF-1.95 version to set DDR  data bus width to 16 bit.

but when board boot , it promote some error info:"DDR4 initial fail"

and I have checked the uboot code,seems that current U-BOOT code doesn’t support 16-bit memory configuration ?

could you help me check whether the problem exists under sdk6.0 or not
