dttool
A tool for viewing and manipulating DeviceTree files.
To compile and run, run make, then move or execute ./dttool.
The view implementation is not perfect, as some values may appear as strings, whereas other strings are cut off due to NULL bytes.
Use --hex to view the hex representation.
Feel free to submit issues or pull requests.
Tested on an extracted DeviceTree.n56ap.im4p from iOS 12 beta 1.
