Linux: Generating a Device Tree (DTS) file on Zynq-7000

Hi,

I just managed to automatically create a DTS file for Zynq-7020 using libgen, using the device-tree package.

I describe how to do it here:

http://billauer.co.il/blog/?p=2970

But then I noted that Xilinx' relevant Wiki page says this flow isn't supported. So is the Wiki page outdated, or did I just create a DTS file worth nothing?

The said wiki page is: http://wiki.xilinx.com/zynq-linux#toc14

I would, of course, love to try it out myself, but my Zedboard hasn't arrived yet... (hint, hint).

Cheers,
Eli

I'll answer this myself: As the post says now, the DTS file isn't usable.

Hi eli,

To create DTS file for ZedBoard, the ZC702 default devicetree file can be used as a template with following changes:
1. change Memory size to 512mb.
2. remove i2c node
3. modify the ethernet phy as ZC702 and ZedBoard use different phy.

Make sure the FSBL is also rebuilt for ZedBoard.
