[meta-xilinx] should elvis' meta-xilinx layer be synced with poky right now?

[Elvis Dowson]

Hi Robert,
                    I've updated the meta-xilinx repo with a few updates:

- zc702: Add Xylon FrameBuffer HDMI output support as described in the Zynq TRD 14.4 document

- zedboard: Add initial un-tested machine configuration, kernel and u-boot support.

Here are a few settings and code snippets to help you get started

local.conf file settings

For the ZC702 board, I was able to get HDMI output work at 1080p resolution.

I suspect that for the ZedBoard, if I can hazzard a guess
a. console output might work.
b. hdmi output, you might run into issues, but check if the Zynq Base TRD 14.4 instructions work. The current zeboard.dts file doesn't include the definitions for the xylon fb so you might
    want to adapt it from another source to enable it, once you've got the console working.

I briefly tried the xilinx 3.8 kernel, but it hung after displaying "Loading kernel", so I didn't spend anymore time on it. 

I just focussed on updating and testing the xilinx linux 3.6 kernel recipes to the xilinx-v14.4 tag.

Let me know if you run into any issues. 

Best regards,

Elvis Dowson
