10 config BR2_PACKAGE_UBOOT_TOOLS_MKIMAGE
13 The mkimage tool from Das U-Boot bootloader, which allows
14 generation of U-Boot images in various formats.

18 config BR2_PACKAGE_UBOOT_TOOLS_MKIMAGE_FIT_SIGNATURE_SUPPORT
19 bool "FIT signature verification support"
20 select BR2_PACKAGE_OPENSSL
22 Enables support for FIT Signature Verification.
24 Flat Image Trees (FIT) supports hashing of images so that
25 these hashes can be checked on loading. This protects
26 against corruption of the image. However it does not prevent
27 the substitution of one image for another.
29 The signature feature allows the hash to be signed with a
30 private key such that it can be verified using a public key
31 later. Provided that the private key is kept secret and the
32 public key is stored in a non-volatile place, any image can
33 be verified in this way.
35 Enabling this option pulls in a dependency on libssl and
36 libcrypto, and possibly GPL/OpenSSL licensing
37 incompatibility issues.
41 config BR2_PACKAGE_UBOOT_TOOLS_MKENVIMAGE
44 The mkenvimage tool from Das U-Boot bootloader, which allows

53 bootloader, which allows access to the U-Boot environment
