That's news to me. I was thinking all the time that the reason for having 
some dtsi? files with -u-boot suffix was that these were exclusive for u-boot
and the others were shared with linux. If now the content of .*-u-boot.dtsi? 
gets passed to linux too, I no longer know why we separate the files.
Is this for Rockchip or ARM64 or a general rule for all of U-Boot? 
Should I (or someone) try to change documentation or is that already done?
I thought I read something different few months ago ? Maybe I misunderstood...

Ok. I hope I find time to try that some day. 

Thanks for looking at the patch.
