If you think emmc might be added later, might be better to make this 
field STORAGE 2 3 
option STORAGE_UNKNOWN 0

1) It will likely need a field for WiFi Device (not sure if kernel will need a field for WLAN type and/or WLAN interface), I guess it could have a lookup table to get device and then determine what the WLAN type is from there, might want to ask kernel folks what they want / need).

2) add field for AUDIO_CODEC (right now, only 1 will be defined, but that list will likely grow)

3) maybe add field for USB_SENSOR to indicate camera used
