This is certainly the most up to date U-Boot I have worked with (not having worked with U-Boot since 2016 or so).
I'll also note that all of the network booting commands are there. I could try this version of U-Boot to see if
it solves any of my problems with the PC 2 and my Kyu operating system.
After looking around a bit, I type "boot" and it continue, booting Armbian.
