[TF-A] TF-A on iMX8M Mini

Hi,

I am using an iMX8M mini, I have flashed the image with uuu.auto of L4.14.98_2.0.0_ga_images_MX8MMEVK and I have a Linux image with OP-TEE. Now I want to use TF-A but I don't know the steps to continue. I am reading this document ( https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4/guid... and https : //trustedfirmware-a.readthedocs.io/en/latest/plat/imx8m.html https://trustedfirmware-a.readthedocs.io/en/latest/plat/imx8m.html) but I don't know how to get these files: u-boot.bin, u-boot-nodtb.bin, u-boot-spl.bin , DTB U-Boot file (for example, fsl-imx8mq-evk.dtb). Can anyone tell me the steps to follow?

Thanks, best regards Iñigo.
