+	  This option allows to boot the new uImage structure,
+	  Flattened Image Tree. FIT is formally a FDT, which can include
+	  images of various types (kernel, FDT blob, ramdisk, etc.)
+	  in a single blob. To boot this new uImage structure,
+	  pass the address of the blob to the "bootm" command.

+	help
+	  Enables support for FIT Signature Verification.
+
+	  Flat Image Trees (FIT) supports hashing of images so that
+	  these hashes can be checked on loading. This protects
+	  against corruption of the image. However it does not prevent
+	  the substitution of one image for another.
+
+	  The signature feature allows the hash to be signed with a
+	  private key such that it can be verified using a public key
+	  later. Provided that the private key is kept secret and the
+	  public key is stored in a non-volatile place, any image can
+	  be verified in this way.
