12 select BR2_PACKAGE_HOST_DTC
14 Enables support for Flattened Image Tree (FIT).
16 This option allows to boot the new uImage structure,
17 Flattened Image Tree. FIT is formally a FDT, which can include
18 images of various types (kernel, FDT blob, ramdisk, etc.)
19 in a single blob. To boot this new uImage structure,
20 pass the address of the blob to the "bootm" command.
22 if BR2_PACKAGE_HOST_UBOOT_TOOLS_FIT_SUPPORT
24 config BR2_PACKAGE_HOST_UBOOT_TOOLS_FIT_SIGNATURE_SUPPORT
25 bool "FIT signature verification support"
27 Enables support for FIT Signature Verification.
29 Flat Image Trees (FIT) supports hashing of images so that
30 these hashes can be checked on loading. This protects
31 against corruption of the image. However it does not prevent
32 the substitution of one image for another.
34 The signature feature allows the hash to be signed with a
35 private key such that it can be verified using a public key
36 later. Provided that the private key is kept secret and the
37 public key is stored in a non-volatile place, any image can
38 be verified in this way.
