+  U-Boot also has commands to access UBIFS partitions:
+    \begin{itemize}
+    \item \code{ubifsmount <volume-name>}\\
+	Mount the specified volume. Example:\\
+        \code{ubifsmount root}
+    \item \code{ubifsload <addr> <filename> [bytes]}\\
+	Load file contents at the specified address. Example:\\
+	\code{ubifsload 0x21000000 boot/zImage}
+    \item Other commands: \code{ubifsls} and \code{ubifsumount}
+    \end{itemize}
+    This shows that to optimize space, the kernel and DTB can
+    also be stored in a UBIFS partition. Otherwise, the DTB volume
+    consumes an entire LEB.
