NAME #

mainbus - device tree root

SYNOPSIS #

mainbus0 at root

DESCRIPTION #

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.
