Okay so just to check my understanding, the reason we need this here (even if empty) is because it is defined in `pub trait Flashrom` and now `cmd.rs` needs an implementation, even if empty? Can this no-op fn be removed from cmd.rs, or is it required?

I am not sure whether we get votes from Ed and Evan, maybe not, I will try to finish review by myself, so that's why I am having questions :)
