Good question. Actually I don't see why it would matter at all, what
matters is to unlock in order to erase or write.

I don't think any other part of flashrom bit twiddling does restore,
I'm not sure it actually matters anywhere?

I guess our policy is to leave bits unlocked. I'll read up on the PMC
chips and send a patch to remove the locking if it doesn't seem to be
harmful.
