+/** @file\r
+  Deal with devices that just exist in memory space.\r
+  \r
+  To follow the EFI driver model you need a root handle to start with. An\r
+  EFI driver will have a driver binding protocol (Supported, Start, Stop) \r
+  that is used to layer on top of a handle via a gBS->ConnectController. \r
+  The first handle has to just be in the system to make that work. For\r
+  PCI it is a PCI Root Bridge IO protocol that provides the root. \r
+  \r
+  On an embedded system with MMIO device we need a handle to just \r
+  show up. That handle will have this protocol and a device path \r
+  protocol on it. \r
+  \r
+  For an ethernet device the device path must contain a MAC address device path\r
+  node.\r
