linux開發縮寫

1.CONFIG_OF

在一些驅動中常常看到#ifdef CONFIG_OF，這裏的OF是Open Firmware。

Open Firmware. This was invented long time ago when Apple was producing laptops based on PowerPC CPUs. Openfirmware provides a good description of the devices connected to the platform. In Linux kernel the part that works with device data is called Device Tree (DT). More details in the Usage model.
