[Buildroot] [PATCH v8 1/3] package/rockchip-rkbin: new package

[Kilian Zinnecker]

Hello Yann, all

thanks for your review, fixes and applying the patches. And sorry for the late 
answer. What I write now is imho not so important anymore, still I want to 
give some reply:

I personally still favor it, but its not so important to me and I can 
understand, that you don't see much need at the moment and probably prefer to 
keep it simple, so I am totally fine with dropping the custom version stuff. As 
you say: If need arises, we can then revaluate.

Agreed. However, you introduced some typo on one occasion, by snipping "Full" 
and "path" to "Fath ;)

Thanks, seems to work on my PC.

Great, thanks! I did actually have in mind, that the custom version and the 
(in older versions not existing) LICENSE file may cause problems. But I didn't 
know what to do about it and forgot to ask here. Thanks!

Thanks, much better of course!

Thanks for reviewing!
