It sounds reasonable for me. The WIFI support would be really 
interesting because our configs don't contain that but I'm a bit 
sceptical to the changes that are not accepted by the upstream (or maybe 
I haven't noticed PR with devicetree changes on the linux mailing 
list?). There is also couple of things on my TODO list that could be 
improved within support of those boards so if everyone is ok with the 
above changes let's start from that.
