really, i'm the only one who wrote a driver ? that's boring.

i guess this isnt trying to handle OTP stuff that exists in the MTD
layer already ?

the datasheets say 64K *bits* :). i think all our datasheets tend to
use bits rather than bytes because they're stupid and bigger numbers
always means better parts !

but yes, on-chip OTP on all relevant Blackfin parts today are 8KiB in
size. 0x200 128bit pages is how things are organized.
