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. - * - *******************************************************************************/ -/* includes */ - -/* defines */ -/* SDMA command macros */ -#define ETH_ENABLE_TX_QUEUE(tx_queue, eth_port) \ - MV_REG_WRITE(MV64360_ETH_TRANSMIT_QUEUE_COMMAND_REG(eth_port), (1 << tx_queue)) - -#define ETH_DISABLE_TX_QUEUE(tx_queue, eth_port) \ - MV_REG_WRITE(MV64360_ETH_TRANSMIT_QUEUE_COMMAND_REG(eth_port),\ - (1 << (8 + tx_queue))) - -#define ETH_ENABLE_RX_QUEUE(rx_queue, eth_port) \ -MV_REG_WRITE(MV64360_ETH_RECEIVE_QUEUE_COMMAND_REG(eth_port), (1 << rx_queue)) - -#define ETH_DISABLE_RX_QUEUE(rx_queue, eth_port) \ -MV_REG_WRITE(MV64360_ETH_RECEIVE_QUEUE_COMMAND_REG(eth_port), (1 << (8 + rx_queue))) - -#define CURR_RFD_GET(p_curr_desc, queue) \ - ((p_curr_desc) = p_eth_port_ctrl->p_rx_curr_desc_q[queue]) - -#define CURR_RFD_SET(p_curr_desc, queue) \ - (p_eth_port_ctrl->p_rx_curr_desc_q[queue] = (p_curr_desc)) - -#define USED_RFD_GET(p_used_desc, queue) \ - ((p_used_desc) = p_eth_port_ctrl->p_rx_used_desc_q[queue]) - -#define USED_RFD_SET(p_used_desc, queue)\ -(p_eth_port_ctrl->p_rx_used_desc_q[queue] = (p_used_desc)) - - -#define CURR_TFD_GET(p_curr_desc, queue) \ - ((p_curr_desc) = p_eth_port_ctrl->p_tx_curr_desc_q[queue]) - -#define CURR_TFD_SET(p_curr_desc, queue) \ - (p_eth_port_ctrl->p_tx_curr_desc_q[queue] = (p_curr_desc)) - -#define USED_TFD_GET(p_used_desc, queue) \ - ((p_used_desc) = p_eth_port_ctrl->p_tx_used_desc_q[queue]) - -#define USED_TFD_SET(p_used_desc, queue) \ - (p_eth_port_ctrl->p_tx_used_desc_q[queue] = (p_used_desc)) - -#define FIRST_TFD_GET(p_first_desc, queue) \ - ((p_first_desc) = p_eth_port_ctrl->p_tx_first_desc_q[queue]) - -#define FIRST_TFD_SET(p_first_desc, queue) \ - (p_eth_port_ctrl->p_tx_first_desc_q[queue] = (p_first_desc)) - - -/* Macros that save access to desc in order to find next desc pointer */ -#define RX_NEXT_DESC_PTR(p_rx_desc, queue) (ETH_RX_DESC*)(((((unsigned int)p_rx_desc - (unsigned int)p_eth_port_ctrl->p_rx_desc_area_base[queue]) + RX_DESC_ALIGNED_SIZE) % p_eth_port_ctrl->rx_desc_area_size[queue]) + (unsigned int)p_eth_port_ctrl->p_rx_desc_area_base[queue]) - -#define TX_NEXT_DESC_PTR(p_tx_desc, queue) (ETH_TX_DESC*)(((((unsigned int)p_tx_desc - (unsigned int)p_eth_port_ctrl->p_tx_desc_area_base[queue]) + TX_DESC_ALIGNED_SIZE) % p_eth_port_ctrl->tx_desc_area_size[queue]) + (unsigned int)p_eth_port_ctrl->p_tx_desc_area_base[queue]) - -#define LINK_UP_TIMEOUT 100000 -#define PHY_BUSY_TIMEOUT 10000000 - -/* locals */ - -/* PHY routines */ -static void ethernet_phy_set (ETH_PORT eth_port_num, int phy_addr);
