The Nano 3G keeps everything behind the S5L8702 flash controller and
Apple's FTL ("Whimory"), and nand-nano3g.c was a stub, so the port had
no storage at all. This is the flash driver, the FTL and the wiring that
makes the NAND Rockbox's disk. The three are one change because neither
half is usable without the other: the driver alone cannot see a
filesystem, and the FTL alone has nothing to drive.
Testing evidence: firmware/target/arm/s5l8702/ipodnano3g/TESTING.md.
