+  Format for Android DTB/DTBO partitions. It's kind of archive with
+  dtb/dtbo files. Used only when there is a separate unique partition
+  (dtb, dtbo) on an android device to organize device tree files.
+  The format consists of a header with info about size and number
+  of device tree entries and the entries themselves. This format
+  description could be used to extract device tree entries from a
+  partition images and decompile them with dtc (device tree compiler).
