mainbus — device
tree root
mainbus0 at root
mainbus provides an abstraction for all
system buses to attach to. It is the start of the device tree and always
attached. It is not a physical device as such, but an abstraction to which
other devices may attach.
The actual buses which attach are largely machine-dependent; refer to the individual man pages for more information.
