PS1, Line 9: which are not restricted
Verification needs to be taken into account:
- If any region is read-locked, then --noverify-all must be used. (There was brief discussion of enabling --noverify-all by default for the ME region case, since that's a given).

- The region specified must not be read locked if --noverify-all is used, since "write-only" is a valid permission.
