Hi Steffen,
 
if that agrees with the free and open source software idea is to discuss by the flashrom owners (I think you deserve an answer by the owners…)
 
Nevertheless IŽd like to try it to look if it performs better than libftdi (at least for debugging where time could be saved).
Would be nice if you could make it available in any way! (via Mail/git/etc.)
 
Regards,
 
Simon
