Raymond already raised this - Changing this to ecdsa521 breaks
backwards compatibility - existing FIT images signed with algo =
"sha256,secp521r1" will no longer verify.

If consistency is desired, I suspect the better approach would be to
support both names during verification (the old name for
compatibility, the new name going forward). What do you think?

Simon
