WebNov 23, 2012 · So the chosen solution was a device tree, also referred to as Open Firmware (abbreviated OF) or Flattened Device Tree (FDT). This is essentially a data structure in byte code format (that is, not human-readable) which contains information that is helpful to the kernel when booting up. The boot loader copies that chunk of data into a … WebLinux Kernel Configuration. └─> Device Drivers. └─> Device Tree and Open Firmware support. └─> Support for device tree in /proc.

Rather than hard coding every detail of a device into an operating system, many aspect of the hardware can be described in a data structure that is passed to the operating system at boot time. The device tree is used both by Open Firmware, and in the standalone
WebA device specifier is a text string that identifies a node in the device tree. It may include optional arguments to use when opening that node. The general form of a full pathname is: / component / component / ... Open Firmware will do its best to locate the node anyway. Thus, in many cases, an abbreviated form of the above path would work, e.g ...
