Hm, this flash memory isn't NAND, it is just memory-mapped
NOR flash.

The example for CFI NOR flash in
Documentation/devicetree/bindings/mtd/jedec,spi-nor.yaml
clearly uses the node name "flash@"

There is however a real NAND and serial flash memory
controller at 0x65000000, but I haven't seen a platform
that uses it.

The extra compatible string "cortina,gemini-flash"
turns on some Gemini-specific checks, but it
goes into the global system controller, not the NAND
controller, as the system controller confusingly have
some registers for detecting NOR memory config.
drivers/mtd/maps/physmap-gemini.c
