     @mntmn U-Boot? Yea, it's usually adjusted and modified copies to fit the driver model. That is one reason why we created LinuxBoot, essentially dropping the main U-Boot and replacing it with Linux, so you get the well-maintained drivers.

     @CyReVolt how does that work in practice, i.e. how would i get started on lets say bananapi cm4?

     @mntmn With LinuxBoot?
     If only it were that trivial... that is the missing piece to the puzzle, unfortunately. x)

     The general flow would be
     init firmware -> LinuxBoot -> final OS

     and then, "it depends"

     on Aarch64, it's usually SPL -> TF-A -> LinuxBoot -> OS

     I have no idea how that would be integrated, tbh, but it's definitely possible. Part of that would be defining the flash layout.

     The BPi CM4 with its eMMC flash is writable via fastboot, I would think? That should make it approachable.
