Support for higher levels of ARM SystemReady seem like they’re poorly supported in the Linux ecosystem right now.
ARM boards nearly always require a devicetree entry for that specific board.
This may not be entirely a Linux problem, but my understanding is that some of the x1 elite laptops we’ve seen DeviceTree entries added in the Linux kernel are using SystemReady ES or SystemReady SR on Windows
