In linux kernel since version 2.6.23 (release Date: 2007-10-09)
This specifies the device tree source (.dts) file to be
compiled and included when building the bootwrapper. If a
relative filename is given, then it will be relative to
arch/powerpc/boot/dts. If you are not using the bootwrapper,
or do not need to build a dts into the bootwrapper, this
field is ignored.
For example, this is required when building a cuImage target
for an older U-Boot, which cannot pass a device tree itself.
Such a kernel will not work with a newer U-Boot that tries to
pass a device tree (unless you tell it not to). If your U-Boot
does not mention a device tree in "help bootm", then use the
cuImage target and specify a device tree here. Otherwise, use
the uImage target and leave this field blank.
