Using u-boot-imx 2018.03 with zeus branch

Bel Hadj Salem Talel

Hi all,
I'm working on a custom board based on IMX8MM.
My RAM calibration tool works only with u-boot 2018.03 to 2018.04, and I already have a u-boot recipe with all the patches necessary.
In sumo branch all worked well.
The u-boot 2018.03 uses device tree files with names like "fsl-imx8mm-ddr3l-val.dts" , and in the final deploy/imx-boot-tools I found the correct fsl-imx8mm-ddr3l-val.dtb file.
But now in zeus , imx-boot looks for files named like "imx8mm-ddr3l-val.dts" , so when I'm using u-boot 2018.03 in zeus , in the final deploy I do not find fsl-imx8mm-ddr3l-val.dtb , but I find imx8mm-ddr3l-val.dtb
and with that file my board cannot be flashed with "uuu" utility because it is not the right dts for the custom board,
When I look into my u-boot 2018 build I find the currect fsl-imx8mm-ddr3l-val.dtb under the build directory ,
My question is how can I fix it , or how can I tell imx-boot to look for the right file from u-boot ?

Thanks ,Talel
