Just FYI. What's currently in the tree may be slow, but it should work
reliably for reads and writes, and be 4x faster than the old code. I
expect 5-10 minutes for read and erase (because erase does a read to
verify), and too long (40 minutes, maybe more, maybe less) for write.
Write hasn't seen any optimization yet.

 >16 byte non-opaque transfers still have to be figured out on the new
SF100 software/firmware. Does the new software/firmware have any size
limitations for user-defined command streams? If not, a USB log of
sending "03 00 00 00" and receiving 32 bytes, and a log of the same
sequence receiving 64 bytes, both with the new firmware, would be very
helpful.

Regards,
Carl-Daniel
