config ARM_APPENDED_DTB

	bool "Use appended device tree blob to zImage (EXPERIMENTAL)"

	depends on OF && !ZBOOT_ROM && EXPERIMENTAL

	help

	  With this option, the boot code will look for a device tree binary

	  (DTB) appended to zImage

	  (e.g. cat zImage <filename>.dtb > zImage_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 zImage.  Do not leave this option active in a production kernel

	  if you don't intend to always append a DTB.  Proper passing of the

	  location into r2 of a bootloader provided DTB is always preferable

	  to this option.



config ARM_ATAG_DTB_COMPAT

	help

	  Some old bootloaders can't be updated to a DTB capable one, yet

	  they provide ATAGs with memory configuration, the ramdisk address,

	  the kernel cmdline string, etc.  Such information is dynamically

	  provided by the bootloader and can't always be stored in a static

	  DTB.  To allow a device tree enabled kernel to be used with such

	  bootloaders, this option allows zImage to extract the information

	  from the ATAG list and store it at run time into the appended DTB.
