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.
