Where fvp.dtb exists? , I couldn't find it.

Is the dtb file you are generating to with the kernel compilation. You need to copy it over and *rename* it as fvp.dtb.

Sorry for disturbing, but which one:

This is not the morello kernel you compiled with the OPTEE fixes. That kernel should have a "morello-fvp.dtb" which you need to rename into "fvp.dtb".

Thanks.
