- <Description>Cirrus Logic 5430 Controller Driver.This driver is a sample implementation
- of the UGA Draw Protocol for the Cirrus Logic 5430 family of PCI video controllers.
- This driver is only usable in the EFI pre-boot environment. This sample is
- intended to show how the UGA Draw Protocol is able to function. The UGA I/O
- Protocol is not implemented in this sample. A fully compliant EFI UGA driver
- requires both the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's
- documentation on UGA for details on how to write a UGA driver that is able
- to function both in the EFI pre-boot environment and from the OS runtime.</Description>

- Data - Array of pointers to the buffers of data that will be transmitted
- to USB device or received from USB device.
- DataLength - When input, indicates the size, in bytes, of the data buffer
- specified by Data. When output, indicates the actually
- transferred data size.
- DataToggle - A pointer to the data toggle value. On input, it indicates
- the initial data toggle value the bulk transfer should adopt;
- on output, it is updated to indicate the data toggle value
- of the subsequent bulk transfer.
- Translator - A pointr to the transaction translator data.
- TimeOut - Indicates the maximum time, in microseconds, which the
- transfer is allowed to complete.
- TransferResult - A pointer to the detailed result information of the
- bulk transfer.

- 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[in] *IdeDev
- pointer pointing to IDE_BLK_IO_DEV data structure, used

- is not supported by this IDE driver.

- 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.

- Routine Description:
- Submits bulk transfer to a bulk endpoint of a USB device.
-
- Arguments:
-
- This A pointer to the EFI_USB_HC_PROTOCOL instance.
-
- DeviceAddress Represents the address of the target device on the USB,
- which is assigned during USB enumeration.
- EndPointAddress The combination of an endpoint number and an
- endpoint direction of the target USB device.
- Each endpoint address supports data transfer in
- one direction except the control endpoint
- (whose default endpoint address is 0).
- It is the caller's responsibility to make sure that
- the EndPointAddress represents a bulk endpoint.
-
- MaximumPacketLength Indicates the maximum packet size the target endpoint
- is capable of sending or receiving.
-
- Data A pointer to the buffer of data that will be transmitted
- to USB device or received from USB device.
- DataLength When input, indicates the size, in bytes, of the data buffer
- specified by Data. When output, indicates the actually
- transferred data size.
-
- DataToggle A pointer to the data toggle value. On input, it indicates
- the initial data toggle value the bulk transfer should adopt;
- on output, it is updated to indicate the data toggle value
- of the subsequent bulk transfer.
-
- TimeOut Indicates the maximum time, in microseconds, which the
- transfer is allowed to complete.
-
- TransferResult A pointer to the detailed result information of the
- bulk transfer.
-
- Returns:
- EFI_SUCCESS
- The bulk transfer was completed successfully.
- EFI_OUT_OF_RESOURCES
- The bulk transfer could not be submitted due to lack of resource.
- EFI_INVALID_PARAMETER
- Some parameters are invalid.
- EFI_TIMEOUT
- The bulk transfer failed due to timeout.
- EFI_DEVICE_ERROR
- The bulk transfer failed due to host controller or device error.
- Caller should check TranferResult for detailed error information.

-
- DataToggle A pointer to the data toggle value. On input, it is valid
- when IsNewTransfer is TRUE, and it indicates the initial
- data toggle value the asynchronous interrupt transfer
- should adopt.
- On output, it is valid when IsNewTransfer is FALSE,
- and it is updated to indicate the data toggle value of
- the subsequent asynchronous interrupt transfer.
-
- PollingInterval Indicates the interval, in milliseconds, that the
- asynchronous interrupt transfer is polled.
- This parameter is required when IsNewTransfer is TRUE.
-
- DataLength Indicates the length of data to be received at the
- rate specified by PollingInterval from the target
- asynchronous interrupt endpoint. This parameter
- is only required when IsNewTransfer is TRUE.
-
- CallBackFunction The Callback function.This function is called at the
- rate specified by PollingInterval.This parameter is
- only required when IsNewTransfer is TRUE.
-

-/*++
-
-Routine Description:
- This routine determines the operational state of the UNDI. It updates the state flags in the
- Command Descriptor Block based on information derived from the AdapterInfo instance data.
-
- To ensure the command has completed successfully, CdbPtr->StatCode will contain the result of
- the command execution.
-
- The CdbPtr->StatFlags will contain a STOPPED, STARTED, or INITIALIZED state once the command
- has successfully completed.
-
- Keep in mind the AdapterInfo->State is the active state of the adapter (based on software
- interrogation), and the CdbPtr->StateFlags is the passed back information that is reflected
- to the caller of the UNDI API.
-
-Arguments:
- CdbPtr - Pointer to the command descriptor block.
- AdapterInfo - Pointer to the NIC data structure information which the UNDI driver is layering on..

-UNDI_Start (

-/*++
-
-Routine Description:
- This routine is used to change the operational state of the UNDI from stopped to started.
- It will do this as long as the adapter's state is PXE_STATFLAGS_GET_STATE_STOPPED, otherwise
- the CdbPtr->StatFlags will reflect a command failure, and the CdbPtr->StatCode will reflect the
- UNDI as having already been started.
-
- This routine is modified to reflect the undi 1.1 specification changes. The
- changes in the spec are mainly in the callback routines, the new spec adds
- 3 more callbacks and a unique id.
- Since this UNDI supports both old and new undi specifications,
- The NIC's data structure is filled in with the callback routines (depending
- on the version) pointed to in the caller's CpbPtr. This seeds the Delay,
- Virt2Phys, Block, and Mem_IO for old and new versions and Map_Mem, UnMap_Mem
- and Sync_Mem routines and a unique id variable for the new version.
- This is the function which an external entity (SNP, O/S, etc) would call
- to provide it's I/O abstraction to the UNDI.
-
- It's final action is to change the AdapterInfo->State to PXE_STATFLAGS_GET_STATE_STARTED.

- CdbPtr - Pointer to the command descriptor block.
- AdapterInfo - Pointer to the NIC data structure information which the UNDI driver is layering on..

-Routine Description:
- This routine is used to place a packet into the transmit queue. The data buffers given to

-
- When the packets are transmitted, a transmit complete interrupt is generated (if interrupts
- are disabled, the transmit interrupt status is still set and can be checked using the UNDI_Status

-
- Some implementations and adapters support transmitting multiple packets with one transmit
- command. If this feature is supported, the transmit CPBs can be linked in one transmit
- command.
-
- All UNDIs support fragmented frames, now all network devices or protocols do. If a fragmented
- frame CPB is given to UNDI and the network device does not support fragmented frames
- (see !PXE.Implementation flag), the UNDI will have to copy the fragments into a local buffer

- )
-/*++
-
-Routine Description:
- This routine will detect what phy we are using, set the line
- speed, FDX or HDX, and configure the phy if necessary.
-
- The following combinations are supported:
- - TX or T4 PHY alone at PHY address 1
- - T4 or TX PHY at address 1 and MII PHY at address 0
- - 82503 alone (10Base-T mode, no full duplex support)
- - 82503 and MII PHY (TX or T4) at address 0
-
- The sequence / priority of detection is as follows:
- - PHY 1 with cable termination
- - PHY 0 with cable termination
- - PHY 1 (if found) without cable termination
- - 503 interface
-
- Additionally auto-negotiation capable (NWAY) and parallel
- detection PHYs are supported. The flow-chart is described in
- the 82557 software writer's manual.
-
- NOTE: 1. All PHY MDI registers are read in polled mode.
- 2. The routines assume that the 82557 has been RESET and we have
- obtained the virtual memory address of the CSR.
- 3. PhyDetect will not RESET the PHY.
- 4. If FORCEFDX is set, SPEED should also be set. The driver will
- check the values for inconsistency with the detected PHY
- technology.
- 5. PHY 1 (the PHY on the adapter) may have an address in the range
- 1 through 31 inclusive. The driver will accept addresses in
- this range.
- 6. Driver ignores FORCEFDX and SPEED overrides if a 503 interface
- is detected.
-
-Arguments:
- AdapterInfo - pointer to the structure that contains the NIC's context.
-
-Returns:
- TRUE - If a Phy was detected, and configured correctly.
- FALSE - If a valid phy could not be detected and configured.
