26 bool "Run-time configuration via Device Tree"
29 This feature provides for run-time configuration of U-Boot
30 via a flattened device tree.
33 bool "Board-specific manipulation of Device Tree"
36 U-Boot's device tree (e.g. to delete device from it). This option
37 make the Device Tree writeable and provides a board-specific
38 "board_fix_fdt" callback (called during pre-relocation time), which
39 enables the board initialization to modifiy the Device Tree. The
40 modified copy is subsequently used by U-Boot after relocation.
43 bool "Enable run-time configuration via Device Tree in SPL"
44 depends on SPL && OF_CONTROL
46 Some boards use device tree in U-Boot but only have 4KB of SRAM
47 which is not enough to support device tree. Enable this option to
48 allow such boards to be supported by U-Boot SPL.
51 bool "Enable run-time configuration via Device Tree in TPL"
52 depends on TPL && OF_CONTROL
54 Some boards use device tree in U-Boot but only have 4KB of SRAM
55 which is not enough to support device tree. Enable this option to
56 allow such boards to be supported by U-Boot TPL.
60 depends on OF_CONTROL
62 Normally U-Boot uses a flat device tree which saves space and
64 tree does not support modification from within U-Boot since it
65 can invalidate driver-model device tree offsets. This option
71 depends on OF_CONTROL
75 depends on !SANDBOX
77 If this option is enabled, the device tree will be built and
78 placed as a separate u-boot.dtb file alongside the U-Boot image.
83 If this option is enabled, the device tree will be picked up and
84 built into the U-Boot image. This is suitable for local debugging
86 Boards in the mainline U-Boot tree should not use it.

108 control will be read from a device tree binary, at a memory
109 location passed to U-Boot by the prior stage bootloader.

242 Since SPL normally runs in a reduced memory space, the device tree
243 is cut down to only what is needed to load and start U-Boot. Only
244 nodes marked with the property "u-boot,dm-pre-reloc" will be
245 included. In addition, some properties are not used by U-Boot and
