+ bool "vmlinuz.bin"
+ depends on SYS_SUPPORTS_ZBOOT
+ help
+ With this option, the boot code will look for a device tree binary
+ DTB) appended to raw vmlinuz.bin (with decompressor).
+ (e.g. cat vmlinuz.bin <filename>.dtb > vmlinuz_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 vmlinuz.bin. Do not leave this option active in a production kernel
+ if you don't intend to always append a DTB.
