I fully admit I have no idea what I'm doing here and I basically took one of the existing files, ripped out what I didn't understand and tried to fill in the numbers from the datasheet without really knowing what they mean. This worked well enough for me to get something that looks like a correct dump of the SPI NAND from a board I'm working with. I need the vendor firmware on the board for reverse engineering so I haven't actually tried to write anything yet. The datasheet for this chip is linked. If someone that actually knows what they're doing could take a look and point out my mistakes that would be great.
