- 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.
