I've got an Intel StrataFlash so it's both 16 bits and CFI compliant.  I
quickly checked the files you mentioned and this all seems very simple. 
But I've got a few questions : what is nora.c for (from the name, I
guess it's a NOR flash and from the code I guess it's CFI but that's all
I know)?  and what does SBC stand for ?
