For FIT verification, all the properties of a public key come from "control fdt" pointed to by fdt_blob. In UEFI secure boot, on the other hand, a public key is located and retrieved from dedicated signature database stored as UEFI variables.
Added two fields may hold values of a public key if fdt_blob is NULL, and will be used in rsa_verify_with_pkey() to verify a signature in UEFI sub-system.
