13 This document describes U-Boot's support for a 'live' device tree, meaning
14 that the tree is loaded into a hierarchical data structure within U-Boot.
18 ----------
22 - it is the format produced by the device tree compiler, so no translation
25 - it is fairly compact (e.g. there is no need for pointers)
27 - it is accessed by the libfdt library, which is well tested and stable
38 Driver model scans the entire device tree sequentially on start-up which
40 modified at run-time, a live tree is much faster. Even if no modification
