CONFIG_HASH_INSTRUCTIONS=y in your defconfig 15 CONFIG_HASH_SHA (optional - remove if you want to md5 hash) 16 2. Include the elf-loader's Kconfig under a new menu in your top-level Kconfig 17 like this: 18 19 menu "Tools" 20 source "tools/elfloader/Kconfig" 21 endmenu 22 23Either one of these options will allow the user to select the hashing process. 24 25Please note, this process will add boottime, as hashing a very long file tends to take some time. 26
