I noticed on the Arduino Yun product page that there is only a partial board schematic, not featuring the Linux/WiFi part of the Arduino Yun, and no editable design file. This is different from all other Arduino boards until today, for which full schematics and editable design files have been made …

Is the Arduino Yun still Open Hardware?

What's missing from schematic?

The "MIPS 24K" is the Linux/WiFi chip, aka: "Hornet", AR9331.
