Ahh, yeah, that makes sense. I will change "Fixes" to "Adds" for next 
submission.

OK. I suppose its unlikely that a NAND chip will swap from 8bit to 16bit (or 
vice versa) from one compile to another :).

My thought process was something along the lines of one compiled binary working
on potentially multiple similar boards... Though in thinking about it, that 
seems like a needless requirement. I will change to #ifdefs for smaller code 
size. That's probably more useful overall.

Regards,
Alex
