+	  See doc/uImage.FIT/signature.txt for more details.
+	  The Modular Exponentiation algorithm in RSA is implemented using
+	  driver model. So CONFIG_DM needs to be enabled by default for this
+	  library to function.
+	  The signing part is build into mkimage regardless of this
+	  option. The software based modular exponentiation is built into
+	  mkimage irrespective of this option.
