There is a lot more, so "etc" is correct. 15 minutes of looking gave me this: The manual that tells you what hardware is available and how to program it is CC-NC. Several datasheets are available under NDA only (according to the manual). The GPS/BT firmware. The FM radio chip contains a DSP, probably has read-only firmware. ARM CPU patents and licenses. SIM card firmware if you use GSM/3G. SD card firmware if you use one of those.
