uclinux sopc2dts xml

Hi,

I want to add devicetree to my uclinux system.

http://www.alterawiki.com/wiki/devicetree

In the step

java -jar sopc2dts.jar -t dts -i path_to_your_system.sopcinfo -o path_to_your_system.dts

I got error

Component lcd_display of class altera_avalon_lcd_16207 is unknown

Then I read something fromhttp://sopc.et.ntust.edu.tw/pipermail/nios2-dev/2011-march/005030.html

Seemed like I need to create a sopc_components_*.xml file to describe the unrecognized components. But I don't know how, and I didn't find any tutorial either.

Can anyone give me any advice?

kindly help
