- /** @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.
