> The ECC fuse on 8ULP can't be written twice. If any user did it, the
> ECC value would be wrong then cause accessing problem to the fuse.
> The patch will lock the ECC fuse word to avoid this problem.
> For iMX9, the OTP controller automatically prevents an ECC fuse word to
> be written twice. So it does not need the setting.
