* 1. Issue a PRECHARGE-ALL-BANKS command
* 2. Issue eight CBR REFRESH commands
* 3. Issue a MODE-SET command to initialize the mode register
*
* The initial commands are executed by setting P/LSDMR[OP] and

* "At system reset, initialization software must set up the
* programmable parameters in the memory controller banks registers
* (ORx, BRx, P/LSDMR). After all memory parameters are configured,
* system software should execute the following initialization sequence
* for each SDRAM device.
*
* 1. Issue a PRECHARGE-ALL-BANKS command
* 2. Issue eight CBR REFRESH commands
* 3. Issue a MODE-SET command to initialize the mode register
*
* The initial commands are executed by setting P/LSDMR[OP] and
* accessing the SDRAM with a single-byte transaction."
*
* The appropriate BRx/ORx registers have already been set when we
* get here. The SDRAM can be accessed at the address CFG_SDRAM_BASE.

*
* FILENAME:
*
* xdma_channel.h
*
* DESCRIPTION:
*
* This file contains the DMA channel component implementation. This component
* supports a distributed DMA design in which each device can have it's own
* dedicated DMA channel, as opposed to a centralized DMA design.
* A device which uses DMA typically contains two DMA channels, one for
* sending data and the other for receiving data.
*
* This component is designed to be used as a basic building block for
* designing a device driver. It provides registers accesses such that all
* DMA processing can be maintained easier, but the device driver designer
* must still understand all the details of the DMA channel.
*
* The DMA channel allows a CPU to minimize the CPU interaction required to move
* data between a memory and a device. The CPU requests the DMA channel to
* perform a DMA operation and typically continues performing other processing
* until the DMA operation completes. DMA could be considered a primitive form
* of multiprocessing such that caching and address translation can be an issue.
*
* Scatter Gather Operations
*
* The DMA channel may support scatter gather operations. A scatter gather
* operation automates the DMA channel such that multiple buffers can be
* sent or received with minimal software interaction with the hardware. Buffer
* descriptors, contained in the XBufDescriptor component, are used by the
* scatter gather operations of the DMA channel to describe the buffers to be
* processed.
*
* Scatter Gather List Operations
*
* A scatter gather list may be supported by each DMA channel. The scatter
* gather list allows buffer descriptors to be put into the list by a device
* driver which requires scatter gather. The hardware processes the buffer
* descriptors which are contained in the list and modifies the buffer
* descriptors to reflect the status of the DMA operations. The device driver
* is notified by interrupt that specific DMA events occur including scatter
* gather events. The device driver removes the completed buffer descriptors
* from the scatter gather list to evaluate the status of each DMA operation.
*
* The scatter gather list is created and buffer descriptors are inserted into
* the list. Buffer descriptors are never removed from the list after it's
* creation such that a put operation copies from a temporary buffer descriptor
* to a buffer descriptor in the list. Get operations don't copy from the list
* to a temporary, but return a pointer to the buffer descriptor in the list.
* A buffer descriptor in the list may be locked to prevent it from being
* overwritten by a put operation. This allows the device driver to get a
* descriptor from a scatter gather list and prevent it from being overwritten
* until the buffer associated with the buffer descriptor has been processed.
*
* Typical Scatter Gather Processing
*
* The following steps illustrate the typical processing to use the
* scatter gather features of a DMA channel.
*
* 1. Create a scatter gather list for the DMA channel which puts empty buffer
* descriptors into the list.
* 2. Create buffer descriptors which describe the buffers to be filled with
* receive data or the buffers which contain data to be sent.
* 3. Put buffer descriptors into the DMA channel scatter list such that scatter
* gather operations are requested.
* 4. Commit the buffer descriptors in the list such that they are ready to be
* used by the DMA channel hardware.
* 5. Start the scatter gather operations of the DMA channel.
* 6. Process any interrupts which occur as a result of the scatter gather
* operations or poll the DMA channel to determine the status.
*
* Interrupts
*
* Each DMA channel has the ability to generate an interrupt. This component
* does not perform processing for the interrupt as this processing is typically
* tightly coupled with the device which is using the DMA channel. It is the
* responsibility of the caller of DMA functions to manage the interrupt
* including connecting to the interrupt and enabling/disabling the interrupt.
*
* Critical Sections
*
* It is the responsibility of the device driver designer to use critical
* sections as necessary when calling functions of the DMA channel. This
* component does not use critical sections and it does access registers using
* read-modify-write operations. Calls to DMA functions from a main thread
* and from an interrupt context could produce unpredictable behavior such that
* the caller must provide the appropriate critical sections.
*
* Address Translation
*
* All addresses of data structures which are passed to DMA functions must
* be physical (real) addresses as opposed to logical (virtual) addresses.
*
* Caching
*
* The memory which is passed to the function which creates the scatter gather
* list must not be cached such that buffer descriptors are non-cached. This
* is necessary because the buffer descriptors are kept in a ring buffer and
* not directly accessible to the caller of DMA functions.
*
* The caller of DMA functions is responsible for ensuring that any data
* buffers which are passed to the DMA channel are cache-line aligned if
* necessary.
*
* The caller of DMA functions is responsible for ensuring that any data
* buffers which are passed to the DMA channel have been flushed from the cache.
*
* The caller of DMA functions is responsible for ensuring that the cache is
* invalidated prior to using any data buffers which are the result of a DMA
* operation.
*
* Memory Alignment
*
* The addresses of data buffers which are passed to DMA functions must be
* 32 bit word aligned since the DMA hardware performs 32 bit word transfers.
*
* Mutual Exclusion
*
* The functions of the DMA channel are not thread safe such that the caller
* of all DMA functions is responsible for ensuring mutual exclusion for a
* DMA channel. Mutual exclusion across multiple DMA channels is not
* necessary.
*
* NOTES:
*
* Many of the provided functions which are register accessors don't provide
* a lot of error detection. The caller is expected to understand the impact
* of a function call based upon the current state of the DMA channel. This
* is done to minimize the overhead in this component.

* xipif.h
*
* DESCRIPTION:
*
* The XIpIf component encapsulates the IPIF, which is the standard interface
* that IP must adhere to when connecting to a bus. The purpose of this
* component is to encapsulate the IPIF processing such that maintainability
* is increased. This component does not provide a lot of abstraction from
* from the details of the IPIF as it is considered a building block for
* device drivers. A device driver designer must be familiar with the
* details of the IPIF hardware to use this component.
*
* The IPIF hardware provides a building block for all hardware devices such
* that each device does not need to reimplement these building blocks. The
* IPIF contains other building blocks, such as FIFOs and DMA channels, which
* are also common to many devices. These blocks are implemented as separate
* hardware blocks and instantiated within the IPIF. The primary hardware of
* the IPIF which is implemented by this software component is the interrupt
* architecture. Since there are many blocks of a device which may generate
* interrupts, all the interrupt processing is contained in the common part
* of the device, the IPIF. This interrupt processing is for the device level
* only and does not include any processing for the interrupt controller.
*
* A device is a mechanism such as an Ethernet MAC. The device is made
* up of several parts which include an IPIF and the IP. The IPIF contains most
* of the device infrastructure which is common to all devices, such as
* interrupt processing, DMA channels, and FIFOs. The infrastructure may also
* be referred to as IPIF internal blocks since they are part of the IPIF and
* are separate blocks that can be selected based upon the needs of the device.
* The IP of the device is the logic that is unique to the device and interfaces
* to the IPIF of the device.
*
* In general, there are two levels of registers within the IPIF. The first
* level, referred to as the device level, contains registers which are for the
* entire device. The second level, referred to as the IP level, contains
* registers which are specific to the IP of the device. The two levels of
* registers are designed to be hierarchical such that the device level is
* is a more general register set above the more specific registers of the IP.
* The IP level of registers provides functionality which is typically common
* across all devices and allows IP designers to focus on the unique aspects
* of the IP.
*
* Critical Sections
*
* It is the responsibility of the device driver designer to use critical
* sections as necessary when calling functions of the IPIF. This component
* does not use critical sections and it does access registers using
* read-modify-write operations. Calls to IPIF functions from a main thread
* and from an interrupt context could produce unpredictable behavior such that
* the caller must provide the appropriate critical sections.
*
* Mutual Exclusion
*
* The functions of the IPIF are not thread safe such that the caller of all
* functions is responsible for ensuring mutual exclusion for an IPIF. Mutual
* exclusion across multiple IPIF components is not necessary.
*
* NOTES:
*
* None.

*
* DESCRIPTION:
*
* This function gets the device interrupt ID for the highest priority interrupt
* which is pending from the interrupt ID register. This function provides
* priority resolution such that faster interrupt processing is possible.
* Without priority resolution, it is necessary for the software to read the
* interrupt pending register and then check each interrupt source to determine
* if an interrupt is pending. Priority resolution becomes more important as the
* number of interrupt sources becomes larger.
*
* Interrupt priorities are based upon the bit position of the interrupt in the
* interrupt pending register with bit 0 being the highest priority. The
* interrupt ID is the priority of the interrupt, 0 - 31, with 0 being the
* highest priority. The interrupt ID register is live rather than latched such
* that multiple calls to this function may not yield the same results. A
* special value, outside of the interrupt priority range of 0 - 31, is
* contained in the register which indicates that no interrupt is pending. This
* may be useful for allowing software to continue processing interrupts in a
* loop until there are no longer any interrupts pending.
*
* The interrupt ID is designed to allow a function pointer table to be used
* in the software such that the interrupt ID is used as an index into that
* table. The function pointer table could contain an instance pointer, such
* as to DMA channel, and a function pointer to the function which handles
* that interrupt. This design requires the interrupt processing of the device
* driver to be partitioned into smaller more granular pieces based upon
* hardware used by the device, such as DMA channels and FIFOs.
*
* It is not mandatory that this function be used by the device driver software.
* It may choose to read the pending register and resolve the pending interrupt
* priorities on it's own.

* DESCRIPTION:
*
* This function sets the IP interrupt status register to the specified value.
* This register indicates the status of interrupt sources for the IP of the
* device. The IP is defined as the part of the device that connects to the
* IPIF. The status is independent of whether interrupts are enabled such that
* the status register may also be polled when interrupts are not enabled.
*
* Each bit of the register correlates to a specific interrupt source within the
* IP. All bits of this register are latched. Setting a bit which is zero
* within this register causes an interrupt to be generated. The device global
* interrupt enable register and the device interrupt enable register must be set
* appropriately to allow an interrupt to be passed out of the device. The
* interrupt is cleared by writing to this register with the bits to be
* cleared set to a one and all others to zero. This register implements a
* toggle on write functionality meaning any bits which are set in the value
* written cause the bits in the register to change to the opposite state.
*
* This function writes only the specified value to the register such that
* some status bits may be set and others cleared. It is the caller's
* responsibility to get the value of the register prior to setting the value
* to prevent an destructive behavior.
*
* ARGUMENTS:
*
* RegBaseAddress contains the base address of the IPIF registers.

* This component is a common component because it's primary purpose is to
* prevent code duplication in drivers. A driver which must handle a packet
* FIFO uses this component rather than directly manipulating a packet FIFO.
*
* A FIFO is a device which has dual port memory such that one user may be
* inserting data into the FIFO while another is consuming data from the FIFO.
* A packet FIFO is designed for use with packet protocols such as Ethernet and
* ATM. It is typically only used with devices when DMA and/or Scatter Gather
* is used. It differs from a nonpacket FIFO in that it does not provide any
* interrupts for thresholds of the FIFO such that it is less useful without
* DMA.
*
* @note
*
* This component has the capability to generate an interrupt when an error
* condition occurs. It is the user's responsibility to provide the interrupt
* processing to handle the interrupt. This component provides the ability to
* determine if that interrupt is active, a deadlock condition, and the ability
* to reset the FIFO to clear the condition. In this condition, the device which
* is using the FIFO should also be reset to prevent other problems. This error
* condition could occur as a normal part of operation if the size of the FIFO
* is not setup correctly. See the hardware IP specification for more details.

*
* The Xilinx Ethernet driver component. This component supports the Xilinx
* Ethernet 10/100 MAC (EMAC).
*
* The Xilinx Ethernet 10/100 MAC supports the following features:
* - Simple and scatter-gather DMA operations, as well as simple memory
* mapped direct I/O interface (FIFOs).
* - Media Independent Interface (MII) for connection to external
* 10/100 Mbps PHY transceivers.
* - MII management control reads and writes with MII PHYs
* - Independent internal transmit and receive FIFOs
* - CSMA/CD compliant operations for half-duplex modes
* - Programmable PHY reset signal
* - Unicast, broadcast, and promiscuous address filtering (no multicast yet)
* - Internal loopback
* - Automatic source address insertion or overwrite (programmable)
* - Automatic FCS insertion and stripping (programmable)
* - Automatic pad insertion and stripping (programmable)
* - Pause frame (flow control) detection in full-duplex mode
* - Programmable interframe gap
* - VLAN frame support.
* - Pause frame support
*
* The device driver supports all the features listed above.
*
* <b>Driver Description</b>
*
* The device driver enables higher layer software (e.g., an application) to
* communicate to the EMAC. The driver handles transmission and reception of
* Ethernet frames, as well as configuration of the controller. It does not
* handle protocol stack functionality such as Link Layer Control (LLC) or the
* Address Resolution Protocol (ARP). The protocol stack that makes use of the
* driver handles this functionality. This implies that the driver is simply a
* pass-through mechanism between a protocol stack and the EMAC. A single device
* driver can support multiple EMACs.
*
* The driver is designed for a zero-copy buffer scheme. That is, the driver will
* not copy buffers. This avoids potential throughput bottlenecks within the
* driver.
*
* Since the driver is a simple pass-through mechanism between a protocol stack
* and the EMAC, no assembly or disassembly of Ethernet frames is done at the
* driver-level. This assumes that the protocol stack passes a correctly
* formatted Ethernet frame to the driver for transmission, and that the driver
* does not validate the contents of an incoming frame
*
* <b>PHY Communication</b>
*
* The driver provides rudimentary read and write functions to allow the higher
* layer software to access the PHY. The EMAC provides MII registers for the
* driver to access. This management interface can be parameterized away in the
* FPGA implementation process. If this is the case, the PHY read and write
* functions of the driver return XST_NO_FEATURE.
*
* External loopback is usually supported at the PHY. It is up to the user to
* turn external loopback on or off at the PHY. The driver simply provides pass-
* through functions for configuring the PHY. The driver does not read, write,
* or reset the PHY on its own. All control of the PHY must be done by the user.
*
* <b>Asynchronous Callbacks</b>
*
* The driver services interrupts and passes Ethernet frames to the higher layer
* software through asynchronous callback functions. When using the driver
* directly (i.e., not with the RTOS protocol stack), the higher layer
* software must register its callback functions during initialization. The
* driver requires callback functions for received frames, for confirmation of
* transmitted frames, and for asynchronous errors.
*
* <b>Interrupts</b>
*
* The driver has no dependencies on the interrupt controller. The driver
* provides two interrupt handlers. XEmac_IntrHandlerDma() handles interrupts
* when the EMAC is configured with scatter-gather DMA. XEmac_IntrHandlerFifo()
* handles interrupts when the EMAC is configured for direct FIFO I/O or simple
* DMA. Either of these routines can be connected to the system interrupt
* controller by the user.
*
* <b>Interrupt Frequency</b>
*
* When the EMAC is configured with scatter-gather DMA, the frequency of
* interrupts can be controlled with the interrupt coalescing features of the
* scatter-gather DMA engine. The frequency of interrupts can be adjusted using
* the driver API functions for setting the packet count threshold and the packet
* wait bound values.
*
* The scatter-gather DMA engine only interrupts when the packet count threshold
* is reached, instead of interrupting for each packet. A packet is a generic
* term used by the scatter-gather DMA engine, and is equivalent to an Ethernet
* frame in our case.
*
* The packet wait bound is a timer value used during interrupt coalescing to
* trigger an interrupt when not enough packets have been received to reach the
* packet count threshold.
*
* These values can be tuned by the user to meet their needs. If there appear to
* be interrupt latency problems or delays in packet arrival that are longer than
* might be expected, the user should verify that the packet count threshold is
* set low enough to receive interrupts before the wait bound timer goes off.
*
* <b>Device Reset</b>
*
* Some errors that can occur in the device require a device reset. These errors
* are listed in the XEmac_SetErrorHandler() function header. The user's error
* handler is responsible for resetting the device and re-configuring it based on
* its needs (the driver does not save the current configuration). When
* integrating into an RTOS, these reset and re-configure obligations are
* taken care of by the Xilinx adapter software if it exists for that RTOS.
*
* <b>Device Configuration</b>
*
* The device can be configured in various ways during the FPGA implementation
* process. Configuration parameters are stored in the xemac_g.c files.
* A table is defined where each entry contains configuration information
* for an EMAC device. This information includes such things as the base address
* of the memory-mapped device, the base addresses of IPIF, DMA, and FIFO modules
* within the device, and whether the device has DMA, counter registers,
* multicast support, MII support, and flow control.
*
* The driver tries to use the features built into the device. So if, for
* example, the hardware is configured with scatter-gather DMA, the driver
* expects to start the scatter-gather channels and expects that the user has set
* up the buffer descriptor lists already. If the user expects to use the driver
* in a mode different than how the hardware is configured, the user should
* modify the configuration table to reflect the mode to be used. Modifying the
* configuration table is a workaround for now until we get some experience with
* how users are intending to use the hardware in its different configurations.
* For example, if the hardware is built with scatter-gather DMA but the user is
* intending to use only simple DMA, the user either needs to modify the config
* table as a workaround or rebuild the hardware with only simple DMA. The
* recommendation at this point is to build the hardware with the features you
* intend to use. If you're inclined to modify the table, do so before the call
* to XEmac_Initialize(). Here is a snippet of code that changes a device to
* simple DMA (the hardware needs to have DMA for this to work of course):
* <pre>
* XEmac_Config *ConfigPtr;
*
* ConfigPtr = XEmac_LookupConfig(DeviceId);
* ConfigPtr->IpIfDmaConfig = XEM_CFG_SIMPLE_DMA;
* </pre>
*
* <b>Simple DMA</b>
*
* Simple DMA is supported through the FIFO functions, FifoSend and FifoRecv, of
* the driver (i.e., there is no separate interface for it). The driver makes use
* of the DMA engine for a simple DMA transfer if the device is configured with
* DMA, otherwise it uses the FIFOs directly. While the simple DMA interface is
* therefore transparent to the user, the caching of network buffers is not.
* If the device is configured with DMA and the FIFO interface is used, the user
* must ensure that the network buffers are not cached or are cache coherent,
* since DMA will be used to transfer to and from the Emac device. If the device
* is configured with DMA and the user really wants to use the FIFOs directly,
* the user should rebuild the hardware without DMA. If unable to do this, there
* is a workaround (described above in Device Configuration) to modify the
* configuration table of the driver to fake the driver into thinking the device
* has no DMA. A code snippet follows:
* <pre>
* XEmac_Config *ConfigPtr;
*
* ConfigPtr = XEmac_LookupConfig(DeviceId);
* ConfigPtr->IpIfDmaConfig = XEM_CFG_NO_DMA;
* </pre>
*
* <b>Asserts</b>
*
* Asserts are used within all Xilinx drivers to enforce constraints on argument
* values. Asserts can be turned off on a system-wide basis by defining, at
* compile time, the NDEBUG identifier. By default, asserts are turned on and it
* is recommended that users leave asserts on during development.
*
* <b>Building the driver</b>
*
* The XEmac driver is composed of several source files. Why so many? This
* allows the user to build and link only those parts of the driver that are
* necessary. Since the EMAC hardware can be configured in various ways (e.g.,
* with or without DMA), the driver too can be built with varying features.
* For the most part, this means that besides always linking in xemac.c, you
* link in only the driver functionality you want. Some of the choices you have
* are polled vs. interrupt, interrupt with FIFOs only vs. interrupt with DMA,
* self-test diagnostics, and driver statistics. Note that currently the DMA code
* must be linked in, even if you don't have DMA in the device.
*
* @note
*
* Xilinx drivers are typically composed of two components, one is the driver
* and the other is the adapter. The driver is independent of OS and processor
* and is intended to be highly portable. The adapter is OS-specific and
* facilitates communication between the driver and an OS.
* <br><br>
* This driver is intended to be RTOS and processor independent. It works
* with physical addresses only. Any needs for dynamic memory management,
* threads or thread mutual exclusion, virtual memory, or cache control must
* be satisfied by the layer above this driver.
*
* <pre>
* MODIFICATION HISTORY:
*
* Ver Who Date Changes
* ----- ---- -------- -------------------------------------------------------
* 1.00a rpm 07/31/01 First release
* 1.00b rpm 02/20/02 Repartitioned files and functions
* 1.00b rpm 10/08/02 Replaced HasSgDma boolean with IpifDmaConfig enumerated
* configuration parameter
* 1.00c rpm 12/05/02 New version includes support for simple DMA and the delay
* argument to SgSend
* 1.00c rpm 02/03/03 The XST_DMA_SG_COUNT_EXCEEDED return code was removed
* from SetPktThreshold in the internal DMA driver. Also
* avoided compiler warnings by initializing Result in the
* DMA interrupt service routines.

/**
*
* Send an Ethernet frame in polled mode. The device/driver must be in polled
* mode before calling this function. The driver writes the frame directly to
* the MAC's packet FIFO, then enters a loop checking the device status for
* completion or error. Statistics are updated if an error occurs. The buffer
* to be sent must be word-aligned.
*
* It is assumed that the upper layer software supplies a correctly formatted
* Ethernet frame, including the destination and source addresses, the
* type/length field, and the data field. It is also assumed that upper layer
* software does not append FCS at the end of the frame.
*
* @param InstancePtr is a pointer to the XEmac instance to be worked on.
* @param BufPtr is a pointer to a word-aligned buffer containing the Ethernet
* frame to be sent.
* @param ByteCount is the size of the Ethernet frame.
*
* @return
*
* - XST_SUCCESS if the frame was sent successfully
* - XST_DEVICE_IS_STOPPED if the device has not yet been started
* - XST_NOT_POLLED if the device is not in polled mode
* - XST_FIFO_NO_ROOM if there is no room in the EMAC's length FIFO for this frame
* - XST_FIFO_ERROR if the FIFO was overrun or underrun. This error is critical
* and requires the caller to reset the device.
* - XST_EMAC_COLLISION if the send failed due to excess deferral or late
* collision
*
* @note
*
* There is the possibility that this function will not return if the hardware
* is broken (i.e., it never sets the status bit indicating that transmission is
* done). If this is of concern to the user, the user should provide protection
* from this problem - perhaps by using a different timer thread to monitor the
* PollSend thread. On a 10Mbps MAC, it takes about 1.21 msecs to transmit a
* maximum size Ethernet frame (1518 bytes). On a 100Mbps MAC, it takes about
* 121 usecs to transmit a maximum size Ethernet frame.
*
* @internal
*
* The EMAC uses FIFOs behind its length and status registers. For this reason,
* it is important to keep the length, status, and data FIFOs in sync when
* reading or writing to them.
