Subject: Adding support for BeagleBoard. ArmPkg - Supoprt for ARM specific
 things that can change as the architecture changes. Plus semihosting JTAG
 drivers. EmbeddedPkg - Generic support for an embeddded platform. Including a
 light weight command line shell. BeagleBoardPkg - Platform specifics for
 BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open
 source USB stack (Our internal stack works fine).

+/** @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.
