- * Marvell's Gigabit Ethernet controller low level driver
- *
- * DESCRIPTION:
- *       This file introduce low level API to Marvell's Gigabit Ethernet
- *		controller. This Gigabit Ethernet Controller driver API controls
- *		1) Operations (i.e. port init, start, reset etc').
- *		2) Data flow (i.e. port send, receive etc').
- *		Each Gigabit Ethernet port is controlled via ETH_PORT_INFO
- *		struct.
- *		This struct includes user configuration information as well as
- *		driver internal data needed for its operations.
- *
- *		Supported Features:
- *		- This low level driver is OS independent. Allocating memory for
- *		  the descriptor rings and buffers are not within the scope of
- *		  this driver.
- *		- The user is free from Rx/Tx queue managing.
- *		- This low level driver introduce functionality API that enable
- *		  the to operate Marvell's Gigabit Ethernet Controller in a
- *		  convenient way.
- *		- Simple Gigabit Ethernet port operation API.
- *		- Simple Gigabit Ethernet port data flow API.
- *		- Data flow and operation API support per queue functionality.
- *		- Support cached descriptors for better performance.
- *		- Enable access to all four DRAM banks and internal SRAM memory
- *		  spaces.
- *		- PHY access and control API.
- *		- Port control register configuration API.
- *		- Full control over Unicast and Multicast MAC configurations.
- *
- *		Operation flow:
- *
- *		Initialization phase
- *		This phase complete the initialization of the ETH_PORT_INFO
- *		struct.
- *		User information regarding port configuration has to be set
- *		prior to calling the port initialization routine. For example,
- *		the user has to assign the port_phy_addr field which is board
- *		depended parameter.
- *		In this phase any port Tx/Rx activity is halted, MIB counters
- *		are cleared, PHY address is set according to user parameter and
- *		access to DRAM and internal SRAM memory spaces.
- *
- *		Driver ring initialization
- *		Allocating memory for the descriptor rings and buffers is not
- *		within the scope of this driver. Thus, the user is required to
- *		allocate memory for the descriptors ring and buffers. Those
- *		memory parameters are used by the Rx and Tx ring initialization
- *		routines in order to curve the descriptor linked list in a form
- *		of a ring.
- *		Note: Pay special attention to alignment issues when using
- *		cached descriptors/buffers. In this phase the driver store
- *		information in the ETH_PORT_INFO struct regarding each queue
- *		ring.
- *
- *		Driver start
- *		This phase prepares the Ethernet port for Rx and Tx activity.
- *		It uses the information stored in the ETH_PORT_INFO struct to
- *		initialize the various port registers.
- *
- *		Data flow:
- *		All packet references to/from the driver are done using PKT_INFO
- *		struct.
- *		This struct is a unified struct used with Rx and Tx operations.
- *		This way the user is not required to be familiar with neither
- *		Tx nor Rx descriptors structures.
- *		The driver's descriptors rings are management by indexes.
- *		Those indexes controls the ring resources and used to indicate
- *		a SW resource error:
- *		'current'
- *		This index points to the current available resource for use. For
- *		example in Rx process this index will point to the descriptor
- *		that will be passed to the user upon calling the receive routine.
- *		In Tx process, this index will point to the descriptor
- *		that will be assigned with the user packet info and transmitted.
- *		'used'
- *		This index points to the descriptor that need to restore its
- *		resources. For example in Rx process, using the Rx buffer return
- *		API will attach the buffer returned in packet info to the
- *		descriptor pointed by 'used'. In Tx process, using the Tx
- *		descriptor return will merely return the user packet info with
- *		the command status of  the transmitted buffer pointed by the
- *		'used' index. Nevertheless, it is essential to use this routine
- *		to update the 'used' index.
- *		'first'
- *		This index supports Tx Scatter-Gather. It points to the first
- *		descriptor of a packet assembled of multiple buffers. For example
- *		when in middle of Such packet we have a Tx resource error the
- *		'curr' index get the value of 'first' to indicate that the ring
- *		returned to its state before trying to transmit this packet.
- *
- *		Receive operation:
- *		The eth_port_receive API set the packet information struct,
- *		passed by the caller, with received information from the
- *		'current' SDMA descriptor.
- *		It is the user responsibility to return this resource back
- *		to the Rx descriptor ring to enable the reuse of this source.
- *		Return Rx resource is done using the eth_rx_return_buff API.
- *
- *		Transmit operation:
- *		The eth_port_send API supports Scatter-Gather which enables to
- *		send a packet spanned over multiple buffers. This means that
- *		for each packet info structure given by the user and put into
- *		the Tx descriptors ring, will be transmitted only if the 'LAST'
- *		bit will be set in the packet info command status field. This
- *		API also consider restriction regarding buffer alignments and
- *		sizes.
- *		The user must return a Tx resource after ensuring the buffer
- *		has been transmitted to enable the Tx ring indexes to update.
- *
- *		BOARD LAYOUT
- *		This device is on-board.  No jumper diagram is necessary.
- *
- *		EXTERNAL INTERFACE
- *
- *       Prior to calling the initialization routine eth_port_init() the user
- *	 must set the following fields under ETH_PORT_INFO struct:
- *       port_num             User Ethernet port number.
- *       port_phy_addr		    User PHY address of Ethernet port.
- *       port_mac_addr[6]	    User defined port MAC address.
- *       port_config          User port configuration value.
- *       port_config_extend    User port config extend value.
- *       port_sdma_config      User port SDMA config value.
- *       port_serial_control   User port serial control value.
- *       *port_virt_to_phys ()  User function to cast virtual addr to CPU bus addr.
- *       *port_private        User scratch pad for user specific data structures.
- *
- *       This driver introduce a set of default values:
- *       PORT_CONFIG_VALUE           Default port configuration value
- *       PORT_CONFIG_EXTEND_VALUE    Default port extend configuration value
- *       PORT_SDMA_CONFIG_VALUE      Default sdma control value
- *       PORT_SERIAL_CONTROL_VALUE   Default port serial control value
- *
- *		This driver data flow is done using the PKT_INFO struct which is
- *		a unified struct for Rx and Tx operations:
- *		byte_cnt	Tx/Rx descriptor buffer byte count.
- *		l4i_chk		CPU provided TCP Checksum. For Tx operation only.
- *		cmd_sts		Tx/Rx descriptor command status.
- *		buf_ptr		Tx/Rx descriptor buffer pointer.
- *		return_info	Tx/Rx user resource return information.
- *
- *
- *		EXTERNAL SUPPORT REQUIREMENTS
- *
- *		This driver requires the following external support:
- *
- *		D_CACHE_FLUSH_LINE (address, address offset)
- *
- *		This macro applies assembly code to flush and invalidate cache
- *		line.
- *		address        - address base.
- *		address offset - address offset
- *
- *
- *		CPU_PIPE_FLUSH
- *
- *		This macro applies assembly code to flush the CPU pipeline.

-*       4) Clean MAC tables. The reset status of those tables is unknown.
-*       5) Set PHY address.
-*       Note: Call this routine prior to eth_port_start routine and after setting

-*       3. Initialize and enable the SDMA by writing to the SDMA's
-*    configuration and command registers.
-*       After completing these steps, the ethernet port SDMA can starts to
-*       perform Rx and Tx activities.
-*
-*       Note: Each Rx and Tx queue descriptor's list must be initialized prior
