There is a 64Mbit external flash chip on the board. Implement it.

Can probably reuse quite a bit of the work in MK404 for the chip in that, but will need to backport to C and adapt if any of the control commands are different between the two chips.

Worth noting this is required to get mintemp/maxtemp errors working, without external flash the firmware just bootloops.
