+* base and size values.
+*
+* NOTE!!!
+* The size must be in 64Kbyte granularity.
+* The base address must be aligned to the size.
+* The size must be a series of 1s followed by a series of zeros
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* True for success, false otherwise.

+ * 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.
