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.
