* ams: replace sept with tsec firmware This replaces sept with a custom tsec key derivation firmware. NOTE: This does not use any TSEC exploits whatsoever; it is a well-signed TSEC binary assembled with envyas and signed with the real cauth key. For more details, contact SciresM#0524. * fusee: only set SBK if it's readable
