I trust you that we need to do this. The thing is, we need to ensure
flashrom actually does it. ;) Normally, there is no order enforced of
the blocks to be written. But in case of `write_mode == 0` this function
must be called with the last block last (and it mustn't be skipped) and
before that it must be called with the first block (so we know the first
KiB). Currently this happens by coincidence because the whole flash is
erased, the way the core flashrom code is written, we expect that
the last block of the contents to be flashed are not empty, and we
expect that the changes in contents need an erase. We could leave
comments everywhere about this (still with the risk that it breaks
because of changes somewhere else). Or we could try to find a way
to make it work by definition. A hunch tells me that the write
granularity could help there.
