config ANDROID_BOOT_IMAGE
	bool "Enable support for Android Boot Images"

	  This enables support for booting images which use the Android
	  image format header.

config FIT
	bool "Support Flattened Image Tree"
	select MD5
	select SHA1
	help
	  This option allows you 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.
	  FIT is very flexible, supporting compression, multiple images,
	  multiple configurations, verification through hashing and also
	  verified boot (secure boot using RSA).

if FIT

config FIT_EXTERNAL_OFFSET
	hex "FIT external data offset"
	default 0x0
	help
	  This specifies a data offset in fit image.
	  The offset is from data payload offset to the beginning of
	  fit image header. When specifies a offset, specific data
	  could be put in the hole between data payload and fit image
	  header, such as CSF data on i.MX platform.

config FIT_ENABLE_SHA256_SUPPORT
	bool "Support SHA256 checksum of FIT image contents"
	default y
	select SHA256
	help
	  Enable this to support SHA256 checksum of FIT image contents. A
	  SHA256 checksum is a 256-bit (32-byte) hash value used to check that
	  the image contents have not been corrupted.

config FIT_ENABLE_SHA384_SUPPORT
	bool "Support SHA384 checksum of FIT image contents"
	default n
	select SHA384
	help
	  Enable this to support SHA384 checksum of FIT image contents. A
	  SHA384 checksum is a 384-bit (48-byte) hash value used to check that
	  the image contents have not been corrupted. Use this for the highest
	  security.

config FIT_SIGNATURE
	bool "Enable signature verification of FIT uImages"

	help
	  This option enables signature verification of FIT uImages,
	  using a hash signed and verified using RSA. If
	  CONFIG_SHA_PROG_HW_ACCEL is defined, i.e support for progressive
	  hashing is available using hardware, then the RSA library will use
	  it. See doc/uImage.FIT/signature.txt for more details.

	  WARNING: When relying on signed FIT images with a required signature
	  check the legacy image format is disabled by default, so that
	  unsigned images cannot be loaded. If a board needs the legacy image
	  format support in this case, enable it using
	  CONFIG_LEGACY_IMAGE_FORMAT.

	  This option sets a max size in bytes for verified FIT uImages.
	  A sane value of 256MB protects corrupted DTB structures from overlapping
	  device memory. Assure this size does not extend past expected storage
	  space.

	  and in the u-boot support of the FIT image.

config FIT_VERBOSE
	bool "Show verbose messages when FIT images fail"
	help
	  Generally a system will have valid FIT images so debug messages
	  are a waste of code space. If you are debugging your images then
	  you can enable this option to get more verbose information about
	  failures.

config FIT_BEST_MATCH
	bool "Select the best match for the kernel device tree"
	help
	  When no configuration is explicitly selected, default to the
	  one whose fdt's compatibility field best matches that of
	  U-Boot itself. A match is considered "best" if it matches the
	  most specific compatibility entry of U-Boot's fdt's root node.
	  The order of entries in the configuration's fdt is ignored.

config FIT_IMAGE_POST_PROCESS
	bool "Enable post-processing of FIT artifacts after loading by U-Boot"
	depends on TI_SECURE_DEVICE
	help
	  Allows doing any sort of manipulation to blobs after they got extracted
	  from FIT images like stripping off headers or modifying the size of the
	  blob, verification, authentication, decryption etc. in a platform or
	  board specific way. In order to use this feature a platform or board-
	  specific implementation of board_fit_image_post_process() must be
	  provided. Also, anything done during this post-processing step would
	  need to be comprehended in how the images were prepared before being

	  record elapsed time in a particular stage using bootstage_start()
	  before starting and bootstage_accum() when finished. Bootstage will
	  add up all the accumulated time and report it.

	  Normally, IDs are defined in bootstage.h but a small number of
	  additional 'user' IDs can be used by passing BOOTSTAGE_ID_ALLOC

	help
	  Enabling this will make a U-Boot binary that is capable of being
	  booted via NOR.  In this case we will enable certain pinmux early
	  as the ROM only partially sets up pinmux.  We also default to using
	  NOR for environment.
