What about reversing this? Assume all chips don't support fast read and
then mark the ones that do. Then people who are responsible for trying
to use the Dediprog with a particular chip would be the ones to go
through and change the setting for chips they are using.
A list of supported chips for the SF100 is available at the dediprog site:
http://www.dediprog.com/device_support.php
Assuming that the dediprog really does fast read then going through that
list setting .fast_read=1 for each chip listed is a whole lot less work
than grovelling through the data sheet for every chip that flashrom
supports.
I worry that if you add a depends of full dediprog support on a complete
chip audit then it won't happen for a long time. Someone could run
through the list of chips the Dediprog supports in probably an hour or so.
