[U-Boot] Port help for qca board

I have source of an old version of uboot (2012/07) of this board (actually 5... ipq806x general and router r7800,d7800 and other 3 model) Someone can port it to new version or can help me do it? Don't think it would be difficult as we have all the source that we need. Tell me if you need more information. I have a r7800 to test some image.
