I'm sure that, if your motherboard has a single flash chip or you have
removed this chip and plugged it into a programmer, flashrom -r should
backup the whole contents of a chip regardless of its' internal memory
map. But I don't know if this is true for all the possible cases for
the boards with two flash chips (one for BIOS and another for ME) -
i.e. if you're trying to read the contents "internally" (using a
flashrom's internal mode). Hopefully someone could clarify.
