+  The Driver Health Protocol is optionally produced by a driver that follows the 

+  EFI Driver Model.  If an EFI Driver needs to report health status to the platform, 

+  provide warning or error messages to the user, perform length repair operations, 

+  or request the user to make hardware or software configuration changes, then the 

+  Driver Health Protocol must be produced.

+  

+  A controller that is managed by driver that follows the EFI Driver Model and 

+  produces the Driver Health Protocol must report the current health of the 

+  controllers that the driver is currently managing.  The controller can initially 

+  be healthy, failed, require repair, or require configuration.  If a controller 

+  requires configuration, and the user make configuration changes, the controller 

+  may then need to be reconnected or the system may need to be rebooted for the 

+  configuration changes to take affect.  Figure 2-1 below shows all the possible 

+  health states of a controller and the legal transitions between the health states. 

+

+  @param GetHealthStatus     Retrieves the health status of a controller in the 

+                             platform.  This function can also optionally return

+                             Forms that may be repair a controller that is not 

+                             properly configured.

+  @param Repair              Performs a repair operation on a controller in the 

+                             platform.  This function can optionally report repair 

+                             progress information back to the platform.
