This option allows 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. if BR2_PACKAGE_HOST_UBOOT_TOOLS_FIT_SUPPORT config BR2_PACKAGE_HOST_UBOOT_TOOLS_FIT_SIGNATURE_SUPPORT bool "FIT signature verification support" help Enables support for FIT Signature Verification. 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. endif # BR2_PACKAGE_HOST_UBOOT_TOOLS_FIT_SUPPORT config BR2_PACKAGE_HOST_UBOOT_TOOLS_ENVIMAGE bool "Environment image" help Generate a valid binary environment image from a text file describing the key=value pairs of the environment. This option can be useful to build environment configurations as part of a Linux / rootfs only defconfig instead of using post scripts.

Check your U-Boot configuration for the CONFIG_ENV_ADDR_REDUND and CONFIG_ENV_OFFSET_REDUND settings to see if this is the case for your platform. If it is the case, then you should enable this option to ensure that the U-Boot environment image generated by Buildroot is compatible with the "redundant environment" mechanism of U-Boot. endif # BR2_PACKAGE_HOST_UBOOT_TOOLS_ENVIMAGE config BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT bool "Generate a U-Boot boot script" help Generate a U-Boot boot script, given a file listing U-Boot commands to be executed at boot time.
