/**\r
  @par Protocol Description:\r
  This protocol provides the services required to determine if a driver supports a given controller. \r
  If a controller is supported, then it also provides routines to start and stop the controller.\r
  \r
  @param Supported \r
  Tests to see if this driver supports a given controller. This service\r
  is called by the EFI boot service ConnectController(). In\r
  order to make drivers as small as possible, there are a few calling\r
  restrictions for this service. ConnectController() must\r
  follow these calling restrictions. If any other agent wishes to call\r
  Supported() it must also follow these calling restrictions.\r
\r
\r
  @param Start \r
  Starts a controller using this driver. This service is called by the\r
  EFI boot service ConnectController(). In order to make\r
  drivers as small as possible, there are a few calling restrictions for\r
  this service. ConnectController() must follow these\r
  calling restrictions. If any other agent wishes to call Start() it\r
  must also follow these calling restrictions. \r
  \r
  @param Stop \r
  Stops a controller using this driver. This service is called by the\r
  EFI boot service DisconnectController(). In order to\r
  make drivers as small as possible, there are a few calling\r
  restrictions for this service. DisconnectController()\r
  must follow these calling restrictions. If any other agent wishes\r
  to call Stop() it must also follow these calling restrictions.\r
  \r
  @param Version \r
  The version number of the UEFI driver that produced the\r
  EFI_DRIVER_BINDING_PROTOCOL. This field is used by\r
  the EFI boot service ConnectController() to determine\r
  the order that driver's Supported() service will be used when\r
  a controller needs to be started. EFI Driver Binding Protocol\r
  instances with higher Version values will be used before ones\r
  with lower Version values. The Version values of 0x0-\r
  0x0f and 0xfffffff0-0xffffffff are reserved for\r
  platform/OEM specific drivers. The Version values of 0x10-\r
  0xffffffef are reserved for IHV-developed drivers.\r
  \r
  @param ImageHandle \r
  The image handle of the UEFI driver that produced this instance\r
  of the EFI_DRIVER_BINDING_PROTOCOL.\r
  \r
  @param DriverBindingHandle\r
  The handle on which this instance of the\r
  EFI_DRIVER_BINDING_PROTOCOL is installed. In most\r
  cases, this is the same handle as ImageHandle. However, for\r
  UEFI drivers that produce more than one instance of the\r
  EFI_DRIVER_BINDING_PROTOCOL, this value may not be\r
  the same as ImageHandle.\r
