Detailed Description

Deal with devices that just exist in memory space.

To follow the EFI driver model you need a root handle to start with. An EFI driver will have a driver binding protocol (Supported, Start, Stop) that is used to layer on top of a handle via a gBS->ConnectController. The first handle has to just be in the system to make that work. For PCI it is a PCI Root Bridge IO protocol that provides the root.

On an embedded system with MMIO device we need a handle to just show up. That handle will have this protocol and a device path protocol on it.

For an ethernet device the device path must contain a MAC address device path node.
