From 1eac2a71417b6675b11aace72102a2e7fde8f5c6 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 29 Nov 2006 15:42:37 +0100 Subject: [PATCH] Add support for Prodrive P3M750 & P3M7448 (P3Mx) boards This patch adds support for the Prodrive P3M750 (PPC750 & MV64460) and the P3M7448 (MPC7448 & MV64460) PMC modules. Both modules are quite similar and share the same board directory "prodrive/p3mx" and the same config file "p3mx.h".

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.
