This modification of NORway.py attempts to support samsung dualbanked flash chips (e.g. K8Q2815UQB-PI4B). It performs a chip erase (with a22 low then high) then programs the entire flash using unlocked, single-word programming. Programming ranges is not supported because partial erasing is not implemented. Programming will be '''slow''' because it waits for RY after programming every single word. The author's teensy install has EMI issues so they were '''not able to test this code'''! The file works with NORway's original Teensy firmware.
