Nothing wrong with adding support for manual board files later if we have a good reason for it, but at the moment, this seems completely ARM/ARM64 specific. I don't foresee mobile phones with ACPI using this subsystem, but even if we got them, it would be a horrible idea to use hardcoded board specific tables in a platform file, and we should insist that whatever firmware is present has a way to describe the slimbus devices.
