Well, appended device tree is indeed good only for testing purposes
where bootloader is unable to provide one.

Problem with hardcoded partitions is that you need to keep bootloader
and kernel view of partitions the same. That's why U-Boot introduced
CONFIG_FDT_FIXUP_PARTITIONS which will add mtdparts into DTB.
