The Device Tree Compiler, dtc, takes as input a device-tree in
a given format and outputs a device-tree in another format.
- Note that only the library is installed for now.

+ Say 'y' here if you also want the programs on the target:
+ - convert-dtsv0 convert from version 0 to version 1
+ - dtc the device tree compiler
+ - dtdiff compare two device trees (needs bash)
+ - fdtdump print a readable version of a flat device tree
+ - fdtget read values from device tree
+ - fdtput write a property value to a device tree

+ Note: dtdiff requires bash, so if bash is not selected, dtdiff will

+ need dtdiff on the target.
