/** @file
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.
