+	  Enables support for Flattened Image Tree (FIT).
+
+	  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.

+	bool "FIT signature verification support"
+	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.

+	  describing the key=value pairs of the environment.
+
+	  This option can be useful to build enviornment configurations
+	  as part of a Linux / rootfs only defconfig instead of using
+	  post scripts. This supports a hardware use case of a single
+	  bootloader only defconfig but multiple Linux / rootfs
+	  defconfigs with different boot environments.

+	  Some platforms define in their U-Boot configuration that the
+	  U-Boot environment should be duplicated in two locations (for
+	  extra safety). Check your U-Boot configuration for the
+	  CONFIG_ENV_ADDR_REDUND and CONFIG_ENV_SIZE_REDUND settings to
+	  see if this is the case for your platform.
+
+	  If it is the case, then you should enable this option to
+	  ensure that the U-Boot environment image generated by
+	  Buildroot is compatible with the "redundant environment"
+	  mechanism of U-Boot.
