Agreed.

I'll have to disagree with you here. That makes the logic involved to utilize partial writes much more complicated. I think the best default action (and overwhelming usage case) for Flashrom is to handle erase regions automagically as it does now.

We'll need to improve the partial write logic a bit so it calculates all the necessary erase regions and checks to ensure they are all readable and erasable. Much of the work will be done to address issues mentioned earlier in Carl-Daniel's list.
