> Could you please add some description what this is doing and for what this is intended? To have a "DTB overlay feature", it is enough to just enable CONFIG_OF_LIBFDT_OVERLAY.
I will add some description, and yes for DTB overlay feature, it is enough to enable CONFIG_OF_LIBFDT_OVERLAY but we need to do this step before booting the kernel that's why also have to enable CONFIG_OF_SYSTEM_SETUP.

>Apparently you're adding an overlay passed by optee. Doesn't this have to be applied to u-boot's control dtb too?
Yes, we will be applying the overlay passed by optee, yes it will be applied to dtb which will be passed to uboot for kernel booting.
