Almost certainly. That geometry isn't supported yet, for the simple reason
that I haven't actually met a board which does it yet.
Copy the cfi_intelext_*_1_by_16 routines and make 2_by_16 versions. It
shouldn't be difficult. We also need to check the geometry in
cfi_intelext_setup() and make the MTD device's methods point to the right
set of functions.
