Apart from confirming if you are manually enabling these options, can you also give some
details on how you append the dtb to the kernel image?

Most of us use an out-of-tree patch from Grant to do this, which I have shared below [2]

Even without the patch with the below commands [1] to append the dtb, it still works, so it
would be good to know what steps you follow to append the dtb to the kernel image.

Here's how I do it:

ARCH=arm CROSS_COMPILE=${TOOLCHAIN_PATH}/bin/${TOOLCHAIN_PREFIX} nice make -j$CORES zImage am335x-bone.dtb

cat arch/arm/boot/zImage arch/arm/boot/am335x-bone.dtb > arch/arm/boot/zImage-dtb.am335x-bone

scripts/mkuboot.sh -A arm -O linux -C none  -T kernel -a 0x80008000 -e 0x80008000 -n 'Linux-' -d arch/arm/boot/zImage-dtb.am335x-bone arch/arm/boot/uImage-dtb.am335x-bone
