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. Enabling this option pulls in a dependency on libssl and libcrypto, and possibly GPL/OpenSSL licensing incompatibility issues. endif config BR2_PACKAGE_UBOOT_TOOLS_MKENVIMAGE bool "mkenvimage" help The mkenvimage tool from Das U-Boot bootloader, which allows generation of a valid binary environment image from a text file describing the key=value pairs of the environment. config BR2_PACKAGE_UBOOT_TOOLS_FWPRINTENV bool "fw_printenv" default y help The fw_printenv / fw_setenv tools from Das U-Boot bootloader, which allows access to the U-Boot environment from Linux. endif
