--do-not-use-me is the best. But more seriously i think we should it
split it into two options. --all-erased and --check-erased. The first
assumes that all PEB are erased, while the second do the check if the
PEB is erased and if not it will be erased.

So we can handle NAND's, which have a fast erase, and NOR's  which are
very slow. With this we are able to pick the best option for the
manufacturing.
