Orange Pi 4 (Rockchip 3399) U-Boot and kernel sources

It has always proven useful to study the U-Boot and linux kernel sources. The kernel sources can be needlessly annoying, but U-Boot has proven more instructive for things I am interested in. The Orange Pi Xulong area on Github has separate respositories for the kernel and U-Boot, as well as an Orange Pi "Build" repository. Cloning all three of these went surprisingly fast! Even cloning the linux sources went fairly quickly (although the clone "hung" the first time and needed to be restarted).

Confusingly there are two build repositories. The one with all lower case has had activity in the last 3 days, whereas the other has had no activity for about a year. Maybe that tells the story. Both mention the RK3399.

Have any comments? Questions? Drop me a line!
