config BR2_PACKAGE_UBOOT_TOOLS bool "u-boot tools" help Companion tools for Das U-Boot bootloader. http://www.denx.de/wiki/U-Boot/WebHome if BR2_PACKAGE_UBOOT_TOOLS config BR2_PACKAGE_UBOOT_TOOLS_FIT_SUPPORT bool "Flattened Image Tree (FIT) support" select BR2_PACKAGE_DTC select BR2_PACKAGE_DTC_PROGRAMS help Enables support for Flattened Image Tree (FIT). 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_UBOOT_TOOLS_FIT_SUPPORT config BR2_PACKAGE_UBOOT_TOOLS_FIT_SIGNATURE_SUPPORT bool "FIT signature verification support" select BR2_PACKAGE_OPENSSL 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. Enabling this option pulls in a dependency on libssl and libcrypto, and possibly GPL/OpenSSL licensing incompatibility issues. endif config BR2_PACKAGE_UBOOT_TOOLS_MKIMAGE bool "mkimage" help Install the mkimage tool on the target system The mkimage tool from Das U-Boot bootloader, which allows generation of U-Boot images in various formats. config BR2_PACKAGE_UBOOT_TOOLS_MKENVIMAGE bool "mkenvimage" help Install the mkenvimage tool on the target system 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 Install the fw_printenv / fw_setenv tools on the target system The fw_printenv and fw_setenv tools from Das U-Boot bootloader, which allows access to the U-Boot environment from Linux. config BR2_PACKAGE_UBOOT_TOOLS_DUMPIMAGE bool "dumpimage" help Install the dumpimage tool on the target system The dumpimage tool from Das U-Boot bootloader, which allows extraction of data from U-Boot images. endif
