Downstream packages like Debian flash-kernel rely on /proc/device-tree/model to determine how to install an updated kernel image. Most dts files provide this property. It is suggested by IEEE Std 1275-1994. This patch adds a model attribute for Octeon CPUs.

The ePAPR 1.1 standard says:
2.3.2 model
Property: model
Value type: <string>
Description:
The model property value is a <string> that specifies the
manufacturer’s model number of the device.
The recommended format is: “manufacturer,model”, where manufacturer
is a string describing the name of the manufacturer (such as a stock
ticker symbol), and model specifies the model number.
Example:
model = “fsl,MPC8349EMITX”;
