The Linux kernel configuration item CONFIG_MIPS_RAW_APPENDED_DTB has multiple definitions:
arch/mips/KconfigThe configuration item CONFIG_MIPS_RAW_APPENDED_DTB:
(none)With this option, the boot code will look for a device tree binary DTB) appended to raw vmlinux.bin or vmlinuz.bin. (e.g. cat vmlinux.bin <filename>.dtb > vmlinux_w_dtb).
This is meant as a backward compatibility convenience for those systems with a bootloader that can't be upgraded to accommodate the documented boot protocol using a device tree.
Beware that there is very little in terms of protection against this option being confused by leftover garbage in memory that might look like a DTB header after a reboot if no actual DTB is appended to vmlinux.bin. Do not leave this option active in a production kernel if you don't intend to always append a DTB.
arch/mips/KconfigThe configuration item CONFIG_MIPS_RAW_APPENDED_DTB:
