-/**
- Returns the information about the optimum modes for the specified IDE device.
-
- This function is used by the driver entity to obtain the optimum ATA modes for
- a specific device. The IDE controller driver takes into account the following
- while calculating the mode:
- - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()
-
- The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- for all the devices that belong to an enumeration group before calling
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group.
-
- The IDE controller driver will use controller- and possibly platform-specific
- algorithms to arrive at SupportedModes. The IDE controller may base its
- decision on user preferences and other considerations as well. This function
- may be called multiple times because the driver entity may renegotiate the mode
- with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().
-
- The driver entity may collect timing information for various devices in any
- order. The driver entity is responsible for making sure that all the dependencies
- are satisfied. For example, the SupportedModes information for device A that
- was previously returned may become stale after a call to
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.
-
- The buffer SupportedModes is allocated by the callee because the caller does
- not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE
- is defined in a way that allows for future extensibility and can be of variable
- length. This memory pool should be deallocated by the caller when it is no
- longer necessary.
-
- The IDE controller driver for a Serial ATA (SATA) controller can use this
- member function to force a lower speed (first-generation [Gen1] speeds on a
- second-generation [Gen2]-capable hardware). The IDE controller driver can
- also allow the driver entity to stay with the speed that has been negotiated
- by the physical layer.

-/**
- Disqualifies specific modes for an IDE device.
-
- This function allows the driver entity or other drivers (such as platform
- drivers) to reject certain timing modes and request the IDE controller driver
- to recalculate modes. This function allows the driver entity and the IDE
- controller driver to negotiate the timings on a per-device basis. This function
- is useful in the case of drives that lie about their capabilities. An example
- is when the IDE device fails to accept the timing modes that are calculated
- by the IDE controller driver based on the response to the Identify Drive command.
-
- If the driver entity does not want to limit the ATA timing modes and leave that
- decision to the IDE controller driver, it can either not call this function for
- the given device or call this function and set the Valid flag to FALSE for all
- modes that are listed in EFI_ATA_COLLECTIVE_MODE.
-
- The driver entity may disqualify modes for a device in any order and any number
- of times.
-
- This function can be called multiple times to invalidate multiple modes of the
- same type (e.g., Programmed Input/Output [PIO] modes 3 and 4). See the ATA/ATAPI
- specification for more information on PIO modes.
-
- For Serial ATA (SATA) controllers, this member function can be used to disqualify
- a higher transfer rate mode on a given channel. For example, a platform driver
- may inform the IDE controller driver to not use second-generation (Gen2) speeds
- for a certain SATA drive.

- @param[in] Channel The zero-based channel number.
- @param[in] Device The zero-based device number on the Channel.

-/**
- Returns the information about the optimum modes for the specified IDE device.
-
- This function is used by the driver entity to obtain the optimum ATA modes for
- a specific device. The IDE controller driver takes into account the following
- while calculating the mode:
- - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()
-
- The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- for all the devices that belong to an enumeration group before calling
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group.
-
- The IDE controller driver will use controller- and possibly platform-specific
- algorithms to arrive at SupportedModes. The IDE controller may base its
- decision on user preferences and other considerations as well. This function
- may be called multiple times because the driver entity may renegotiate the mode
- with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().
-
- The driver entity may collect timing information for various devices in any
- order. The driver entity is responsible for making sure that all the dependencies
- are satisfied. For example, the SupportedModes information for device A that
- was previously returned may become stale after a call to
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.
-
- The buffer SupportedModes is allocated by the callee because the caller does
- not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE
- is defined in a way that allows for future extensibility and can be of variable
- length. This memory pool should be deallocated by the caller when it is no
- longer necessary.
-
- The IDE controller driver for a Serial ATA (SATA) controller can use this
- member function to force a lower speed (first-generation [Gen1] speeds on a
- second-generation [Gen2]-capable hardware). The IDE controller driver can
- also allow the driver entity to stay with the speed that has been negotiated
- by the physical layer.
-
- @param[in] This The pointer to the EFI_IDE_CONTROLLER_INIT_PROTOCOL instance.

- @retval EFI_INVALID_PARAMETER Device is invalid.
- @retval EFI_INVALID_PARAMETER SupportedModes is NULL.
- @retval EFI_NOT_READY Modes cannot be calculated due to a lack of
- data. This error may happen if
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- and EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyData()
- were not called for at least one drive in the
- same enumeration group.
