What is the status of these patches? I also still have a set of patches
to integrate it with the other ARMv7 machines into multiplatform,
and a series to change some of the PCI handling in all plat-orion
platforms, that I was hoping to either upstream or drop once the
platform itself gets removed.

Did you give up on moving the Cubox to DT, or is this something you
still want to get back?

Ok, that roughly all matches what I was guessing. As I wrote, I
saw most of them have been getting updates and assumed we want
to keep them, but I was not sure if any of them have come to the point
where it's no longer worth updating kernels past v5.10.y for any
reason.
