1785 bool "Use appended device tree blob to zImage (EXPERIMENTAL)"
1786 depends on OF && !ZBOOT_ROM && EXPERIMENTAL
1787 help
1788 With this option, the boot code will look for a device tree binary
1789 (DTB) appended to zImage
1790 (e.g. cat zImage <filename>.dtb > zImage_w_dtb).
1791
1792 This is meant as a backward compatibility convenience for those
1793 systems with a bootloader that can't be upgraded to accommodate
1794 the documented boot protocol using a device tree.
1795
1796 Beware that there is very little in terms of protection against
1797 this option being confused by leftover garbage in memory that might
1798 look like a DTB header after a reboot if no actual DTB is appended
1799 to zImage. Do not leave this option active in a production kernel
1800 if you don't intend to always append a DTB. Proper passing of the
1801 location into r2 of a bootloader provided DTB is always preferable
1802 to this option.

1807 help
1808 Some old bootloaders can't be updated to a DTB capable one, yet
1809 they provide ATAGs with memory configuration, the ramdisk address,
1810 the kernel cmdline string, etc. Such information is dynamically
1811 provided by the bootloader and can't always be stored in a static
1812 DTB. To allow a device tree enabled kernel to be used with such
1813 bootloaders, this option allows zImage to extract the information
1814 from the ATAG list and store it at run time into the appended DTB.
