I'm pondering this change for some days now and am still undecided :-) 
On the one hand you're right ... this doesn't need to be its own file on the 
other hand it creates churn, but I'm inclined to pick it up.

Can you at least provide another patch doing the same for rk3288, so that we 
really standardize on one form for Rockchip SoCs?


Thanks
Heiko
