/** @file\r
  This file declares EFI IDE Controller Init Protocol\r
  The EFI_IDE_CONTROLLER_INIT_PROTOCOL provides the chipset-specific information to\r
  the IDE bus driver. This protocol is mandatory for IDE controllers if the IDE devices behind the\r
  controller are to be enumerated by an IDE bus driver.\r
  There can only be one instance of EFI_IDE_CONTROLLER_INIT_PROTOCOL for each IDE\r
  controller in a system. It is installed on the handle that corresponds to the IDE controller. An IDE\r
  bus driver that wishes to manage an IDE bus and possibly IDE devices in a system will have to\r
  retrieve the EFI_IDE_CONTROLLER_INIT_PROTOCOL instance that is associated with the\r
  controller to be managed.\r
