While the ISAs are (mostly) standardized, the broader hardware support is a mishmash.

ACPI is available, but not widely supported.

Some hardware uses DeviceTree.

Other hardware just expects you to know what devices are connected and how to interact with them.

What about SBSA, it's not universal but at least it's a target.
