I think he thinks 'CFI' is a brand like Intel, AMD etc. :)

However, using the CFI flash driver might not solve the problem alone 
without proposed patches are done and applied to deal with flash chips 
that come all sectors locked on power on.

According to the product briefing, this flash comes up with all sectors 
locked up initially so this is also probably why his custom flash driver 
is also failing the erase attempts (provided that everything else is 
correct).
