14 select BR2_PACKAGE_DTC_PROGRAMS
16 Enables support for Flattened Image Tree (FIT).
18 This option allows to boot the new uImage structure,
19 Flattened Image Tree. FIT is formally a FDT, which can include
20 images of various types (kernel, FDT blob, ramdisk, etc.)
21 in a single blob. To boot this new uImage structure,
22 pass the address of the blob to the "bootm" command.

30 bool "FIT signature verification support"
31 select BR2_PACKAGE_OPENSSL
33 Enables support for FIT Signature Verification.
35 Flat Image Trees (FIT) supports hashing of images so that
36 these hashes can be checked on loading. This protects
37 against corruption of the image. However it does not prevent
38 the substitution of one image for another.
40 The signature feature allows the hash to be signed with a
41 private key such that it can be verified using a public key
42 later. Provided that the private key is kept secret and the
43 public key is stored in a non-volatile place, any image can
44 be verified in this way.
46 Enabling this option pulls in a dependency on libssl and
47 libcrypto, and possibly GPL/OpenSSL licensing
48 incompatibility issues.

82 Install the dumpimage tool on the target system
84 The dumpimage tool from Das U-Boot bootloader, which allows
85 extraction of data from U-Boot images.
