libfdt allows flattened device trees to be represented as a
|
||
|
|
"blob", which is a compact flattened format. This is useful,
|
||
|
|
particularly for embedded systems, such as ARM, because it
|
||
|
|
allows many different devices to be included in a single binary
|
||
|
|
allowing for a high level of portability.
