           Select this config option to add support for the dtb= command
           line parameter, allowing a device tree blob to be loaded into
           memory from the EFI System Partition by the stub.
 
-          The device tree is typically provided by the platform or by
-          the bootloader, so this option is mostly for development
-          purposes only.
+          If the device tree is provided by the platform or by
+          the bootloader this option may not be needed.
+          But, for various development reasons and to maintain existing
+          functionality for bootloaders that do not have such support
+          this option is necessary.
