The u-boot.itb can be generated either from a static .its that can
simply include the needed signature nodes with key-hints or from a
fit-generator script referenced in CONFIG_SPL_FIT_GENERATOR.

In the script-case it will need to know what key to include for the
key-hint and specified algorithm, so add an option for that key-name.

I am missing a file in doc/ describing how this is used.

Best regards
