Device Tree Comparison

We look at differences in device trees between projects to see if they could have a common source.

NOTE: Operating systems (Linux, BSDs, Plan 9...) and firmware (coreboot, U-Boot, ...) differ in terms of design. While general purpose OSes start at the soft platform level (architecture + device tree / UEFI+ACPI), firmware starts at the hardware platform level. I.e., some concerns are ignored by OSes.

Also note that different structures are used for the device trees, hence the filtering in diff/grep below: U-Boot uses a flat directory structure, whereas Linux has subdirectories, and NetBSD takes a copy from Linux with adjustments for its own drivers and other internals.
