currently there exist already some patches that allow to read and write
single sectors with some preparation and the user interface is probably
not what you want (I am talking about layout files that allow to define
and operate on regions of flash space). 

The midterm plan is to make the core of flashrom more library-like,
which would ease the creation of a special purpose tool like the one
you probably require. Note that midterm in flashrom terms can mean some
years since developer time has been rather scarce lately...

All of that is pretty much programmer-agnostic because most of the time
we specify exactly what is sent to the SPI (or other) bus.
