Yet another board which will never have proper upstream support because the SoC vendor refused to implement the ARM BSA standard which would provide EFI/ACPI support instead of relying on undiscoverable devices only exposed through device tree. ACPI isn't perfect but it's way better than device trees which are seldom updated so the device will remain stuck with old kernels.

Devicetree continues to be a massive crutch for arm soc vendors.
