New FreeBSD Foundation Project: Flattened Device Tree

FreeBSD foundation logoThe FreeBSD Foundation has announced another funded project!

“Rafal Jaworowski and Semihalf has been awarded a grant to provide FreeBSD with support for the flattened device tree (FDT) technology. This project allows for describing hardware resources of a computer system and their dependencies in a platform-neutral and portable way.

The main consumers of this functionality are embedded systems whose hardware resources assignment cannot be probed or self-discovered.

The FDT idea is inherited from Open Firmware IEEE 1275 device-tree notion (part of the regular Open Firmware implementation), and among other deployments is used as a basis for Power.org’s embedded platform
reference specification (ePAPR).

Rafal JaworowskiThanks to this project, embedded FreeBSD platforms will grow in a uniform and extensible way of representing hardware devices, compliant with industry standards (ePAPR, Open Firmware), independent of architecture and platform (portable across ARM, MIPS, PowerPC etc.),

said Rafal Jaworoski, FreeBSD Developer.

Semihalf is a privately owned company, based in Krakow, Poland. They specialize in embedded systems design and development, with expertise in both software and hardware. Among their portfolio are FreeBSD ports to high-end embedded processors (including multi-core) with a wide range of peripheral drivers (storage, networking, pattern matching, security engines etc.); most of this work is publicly available from the FreeBSD repository.

You can find out more about the project at http://wiki.freebsd.org/FlattenedDeviceTree.

This project will complete by February 2010.”
