In 2006 CodeGen, Inc released their Open Firmware implementation under a BSL like license. Their code, entirely written in ANSI C, contains the following components:
- SmartFirmware™: an ANSI C implementation of the IEEE-1275 Open Firmware boot firmware standard. Dramatically reduce and ease your firmware development and system bring-up times and costs.
- An ANSI C compiler that generates Open Firmware compatible Forth/Fcode makes it easy to develop drivers for PCI cards and PMC modules.
You can browse the code online.
