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. -michael Regards, Sahil Malhotra
