- 1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this
- same driver's Start() function.
- 2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid
- EFI_HANDLE. In addition, all of these handles must have been created in this driver's
- Start() function, and the Start() function must have called OpenProtocol() on
- ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
-
- @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
- @param[in] ControllerHandle A handle to the device being stopped. The handle must
- support a bus specific I/O protocol for the driver
- to use to stop the device.
- @param[in] NumberOfChildren The number of child device handles in ChildHandleBuffer.
- @param[in] ChildHandleBuffer An array of child handles to be freed. May be NULL
- if NumberOfChildren is 0.
-
- @retval EFI_SUCCESS The device was stopped.
- @retval EFI_DEVICE_ERROR The device could not be stopped due to a device error.

- 2. Sends out ATAPI Inquiry Packet Command to the specified device.
- This command will return inquiry data of the device, which contains
- the device type information.
- 3. Allocate sense data space for future use. We don't detect the media
- presence here to improvement boot performance, especially when CD
- media is present. The media detection will be performed just before
- each BLK_IO read/write

- Get IDE IO port registers' base addresses by mode. In 'Compatibility' mode,
- use fixed addresses. In Native-PCI mode, get base addresses from BARs in
- the PCI IDE controller's Configuration Space.
-
- The steps to get IDE IO port registers' base addresses for each channel
- as follows:
-
- 1. Examine the Programming Interface byte of the Class Code fields in PCI IDE
- controller's Configuration Space to determine the operating mode.
-
- 2. a) In 'Compatibility' mode, use fixed addresses shown in the Table 1 below.
- <pre>
- ___________________________________________
- | | Command Block | Control Block |
- | Channel | Registers | Registers |
- |___________|_______________|_______________|
- | Primary | 1F0h - 1F7h | 3F6h - 3F7h |
- |___________|_______________|_______________|
- | Secondary | 170h - 177h | 376h - 377h |
- |___________|_______________|_______________|
-
- Table 1. Compatibility resource mappings
- </pre>
-
- b) In Native-PCI mode, IDE registers are mapped into IO space using the BARs
- in IDE controller's PCI Configuration Space, shown in the Table 2 below.
- <pre>
- ___________________________________________________
- | | Command Block | Control Block |
- | Channel | Registers | Registers |
- |___________|___________________|___________________|
- | Primary | BAR at offset 0x10| BAR at offset 0x14|
- |___________|___________________|___________________|
- | Secondary | BAR at offset 0x18| BAR at offset 0x1C|
- |___________|___________________|___________________|
-
- Table 2. BARs for Register Mapping
- </pre>
- @note Refer to Intel ICH4 datasheet, Control Block Offset: 03F4h for
- primary, 0374h for secondary. So 2 bytes extra offset should be
- added to the base addresses read from BARs.
-
- For more details, please refer to PCI IDE Controller Specification and Intel

- Get IDE IO port registers' base addresses by mode. In 'Compatibility' mode,
- use fixed addresses. In Native-PCI mode, get base addresses from BARs in
- the PCI IDE controller's Configuration Space.
-
- The steps to get IDE IO port registers' base addresses for each channel
- as follows:
-
- 1. Examine the Programming Interface byte of the Class Code fields in PCI IDE
- controller's Configuration Space to determine the operating mode.
-
- 2. a) In 'Compatibility' mode, use fixed addresses shown in the Table 1 below.
- <pre>
- ___________________________________________
- | | Command Block | Control Block |
- | Channel | Registers | Registers |
- |___________|_______________|_______________|
- | Primary | 1F0h - 1F7h | 3F6h - 3F7h |
- |___________|_______________|_______________|
- | Secondary | 170h - 177h | 376h - 377h |
- |___________|_______________|_______________|
-
- Table 1. Compatibility resource mappings
- </pre>
-
- b) In Native-PCI mode, IDE registers are mapped into IO space using the BARs
- in IDE controller's PCI Configuration Space, shown in the Table 2 below.
- <pre>
- ___________________________________________________
- | | Command Block | Control Block |
- | Channel | Registers | Registers |
- |___________|___________________|___________________|
- | Primary | BAR at offset 0x10| BAR at offset 0x14|
- |___________|___________________|___________________|
- | Secondary | BAR at offset 0x18| BAR at offset 0x1C|
- |___________|___________________|___________________|
-
- Table 2. BARs for Register Mapping
- </pre>
- @note Refer to Intel ICH4 datasheet, Control Block Offset: 03F4h for
- primary, 0374h for secondary. So 2 bytes extra offset should be
- added to the base addresses read from BARs.
-
- For more details, please refer to PCI IDE Controller Specification and Intel
- ICH4 Datasheet.

- This function is called by DiscoverIdeDevice() during its device
- identification.
- Its main purpose is to get enough information for the device media
- to fill in the Media data structure of the Block I/O Protocol interface.
-
- There are 5 steps to reach such objective:
- 1. Sends out the ATAPI Identify Command to the specified device.
- Only ATAPI device responses to this command. If the command succeeds,
- it returns the Identify data structure which filled with information
- about the device. Since the ATAPI device contains removable media,
- the only meaningful information is the device module name.
- 2. Sends out ATAPI Inquiry Packet Command to the specified device.
- This command will return inquiry data of the device, which contains
- the device type information.
- 3. Allocate sense data space for future use. We don't detect the media
- presence here to improvement boot performance, especially when CD
- media is present. The media detection will be performed just before
- each BLK_IO read/write
-
- @param IdeDev pointer pointing to IDE_BLK_IO_DEV data structure, used
