+* The CPU address is compared with the values in the various CPU windows
+* until a match is found and the address is than targeted to that window.
+* This function sets new base and size for one the memory banks
+* (CS0 - CS3). It is the programmer`s responsibility to make sure that
+* there are no conflicts with other memory spaces. When two memory spaces
+* overlap, the MV\92s behavior is not defined .If a bank needs to be closed,
+* set the \92bankLength\92 parameter size to 0x0.
+*
+* INPUT:
+* bank - One of the memory banks (CS0-CS3) as defined in gtMemory.h.

+* DESCRIPTION:
+* In addition to the address decoding mechanism, the CPU has an address

+* value within the remap register. The address remapping is useful when a
+* CPU address range must be reallocated to a different location on the
+* PCI bus. Also, it enables CPU access to a PCI agent located above the
+* 4Gbyte space. On system boot, each of the PCI memory spaces is maped to
+* a defualt value (see CPU interface section in the MV spec for the
+* default values). The remap mechanism does not always produce the desired
+* address on the PCI bus because of the remap mechanism way of working
+* (to fully understand why, please see the 'Address Remapping' section in
+* the MV's spec). Therefor, this function sets a desired remap value to
+* one of the PCI memory windows and return the effective address that
+* should be used when exiting the PCI memory window. You should ALWAYS use
+* the returned value by this function when remapping a PCI window and
+* exiting it. If for example the base address of PCI0 memory 0 is
+* 0x90000000, the size is 0x03ffffff and the remap value is 0x11000000,
+* the function will return the value of 0x91000000 that MUST
+* be used to exit this memory window in order to achive the deisred
+* remapping.

+* 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.

+* 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.

+This file contains status information for the port of the U-Boot to the Marvell Development Board DB64360.
+
+Author: Ronen Shitrit <rshitrit@il.marvell.com>
+
+This U-Boot version is based on the work of Brian Waite and his team from Sky Computers, THANKS A LOT.
+
+Supported CPU Types :
++++++++++++++++++++++
+ IBM750FX (ver 2.3)
+ MPC7455 (ver 2.1)
+
+Supported CPU Cache Library:
+++++++++++++++++++++++++++++
+ L1 and L2 only.
+
+CPU Control:
+++++++++++++
+ Marvell optimized CPU control settings:
+ Big Endian
+ Enable CPU pipeline
+ Data and address parity checking
+ AACK# assert after 2 cycles
+
+U-Boot I/O Interface Support:
++++++++++++++++++++++++++++++
+- Serial Interface (UART)
+ This version of U-Boot supports the SIO U-Boot interface driver, with a PC standard baud rate up to 115200 BPS on the ST16C2552 DUART device located on DB-64360-BP device module.
+- Network Interface
+ This LSP supports the following network devices:
+ o MV64360 Gigabit Ethernet Controller device
+ o Intel 82559 PCI NIC device
+- PCI Interface
+ This LSP supports the following capabilities over the Marvell(r) device PCI0/1 units:
+ o Local PCI configuration header control.
+ o External PCI configuration header control (for other agents on the bus).
+ o PCI configuration application. Scans and configures the PCI agents on the bus.
+ o PCI Internal Arbiter activation and configuration.
+
+Memory Interface Support:
++++++++++++++++++++++++++
+- DDR
+ o DDR auto-detection and configuration. Enables access up to 256 MB, due to the limitations of using only four Base Address Translations (BATs).
+ o Enable DDR ECC in case both DIMM support ECC, and initialize the entire DDR memory by using the idma.
+
+- Devices
+ o Initializes the MV64360 device's chip-selects 0-3 to enable access to the boot flash, main flash, real time clock (RTC), and external SRAM.
+ o JFFS2
+ JFFS2 is a crash/power down safe file system for disk-less embedded devices.
+ This version of U-Boot supports scanning a JFFS2 file system on the large flash and loading files from it.
+
+Unsupported Features:
++++++++++++++++++++++
+ Messaging unit - No support for MV64360 Messaging unit.
+ Watchdog Timer - No support for MV64360 Watchdog unit.
+ L3 cache - No support for L3 cache on MPC7455
+ Dual PCU - No support for Dual CPU
+ PCI-X was never tested
+ IDMA driver - No support for MV64360 IDMA unit.
+
+BSP Special Considerations:
++++++++++++++++++++++++++++
+- DDR DIMM location: Due to PCI specifications, place the larger DIMM module in the MAIN DIMM slot, in order to have full access from the PCI to the DDR while using both DDR slots.
+- DDR DIMM types: Due to architectural and software limitations, the registration, CAS Latency, and ECC of both DIMMS should be identical.
+
+Test Cases:
+###########
+UART:
++++++
+Check that the UART baud rate is configured to 57600 and 115200, and check:
+ Transmit (to the hyper terminal) and Receive (using the keyboard) using Linux minicom.
+ Load S-Record file over the UART using Windows HyperTerminal.
+
+Network:
+++++++++
+Use TFTP application to load a debugged executable and execute it.
+Insert Intel PCI NIC 82557 rev 08 to PCI slots 0-3 Check correct detection of the PCI NIC, correct configuration of the NIC BARs , and load files by using tftp through the PCI NIC.
+
+Memory:
++++++++
+Test DDR DIMMs on DB-64360-BP. See that Uboot report their correct parameters:
+o 128MB DIMM consist of 16 x 64Mbit devices
+o 128MB DIMM consist of 09 x 128Mbit devices @ 266MHz.
+o 256MB DIMM consist of 16 x 128Mbit devices @ 266MHz.
+o 256MB DIMM consist of 09 x 256Mbit devices @ 400MHz.
+o 512MB DIMM consist of 16 x 256Mbit devices @ 333MHz.
+o 512MB DIMM consist of 18 x 256Mbit devices @ 266MHz.
+o GigaB DIMM consist of 36 x 256Mbit devices @ 266MHz registered
+
+For each chip select device perform data access to verify its accessibility.
+
+Create a JFFS2 on the large flash through the Linux holding few files, few dirs and a uImage.
+Load the U-Boot and:
+use the ls command to check correct scan of the JFFS2 on the large flash.
+Use the floads command to copy the uImage from the JFFS2 on the large flash to the DIMM SDRAM, and boot the uImage.
+
+PCI:
+++++
+1)Insert different PCI cards:
+Galileo 64120A rev 10 and 12, Intel Nic 82557 rev 08 and Real Tech NIC 8139 rev10
+on different slots (0-3) of the PCI and check:
+o Correct detection of the PCI devices.
+o Correct address mapping of the PCI devices.
+2)Insert Galileo 64120A rev 10 on different slots (0-3) of the PCI and check writing and reading pci configuration register through the U-Boot.
+
+Booting Linux through the U-Boot (use the bootargs of the U-Boot as a bootcmd to the kernal)
