Storing the hardware serial identifier in serial# means we can change the serial# if we want before USB enumeration - thus making iSerial automatic via OTP but overridable if necessary. This patch reads the defined OTP fuse and sets environment variable "serial#" to the value read. With this patch in place the USB mass storage device will appear in /dev/disk/by-id with a unique name based on the OTP value.
