-* Storage Design

-* storage module simple takes requests from the user, queues
-* the associated DMA requests for action, and then sends
-* the low level requests to the West Bridge firmware.

- * If set to TRUE, the basic numeric types are defined by the
- * West Bridge API code
- *
- * Description
- * The West Bridge API relies on some basic integral types to be
- * defined. These types include uint8_t, int8_t, uint16_t,
- * int16_t, uint32_t, and int32_t. If this macro is defined the
- * West Bridge API will define these types based on some basic
- * assumptions. If this value is set and the West Bridge API is
- * used to set these types, the definition of these types must be
- * examined to insure that they are appropriate for the given
- * target architecture and compiler.
- *
- * Notes
- * It is preferred that if the basic platform development
- * environment defines these types that the CY_DEFINE_BASIC_TYPES
- * macro be undefined and the appropriate target system header file
- * be added to the file cyashaldef.h.

- This function finds the device object given the HAL tag

- Description
- The user associats a device TAG with each West Bridge device
- created. This tag is passed from the API functions to and HAL

- tag is also passed in from the user back into the API via
- interrupt functions. This function allows the API to find the
- device structure associated with a given tag.
-
- Notes
- This function does a simple linear search for the device based
- on the TAG. This function is called each time an West Bridge
- interrupt handler is called. Therefore this works fine for a
- small number of West Bridge devices (e.g. less than five).
- Anything more than this and this methodology will need to be

-/*@@DMA Overview
- This module manages the DMA operations to/from the West Bridge
- device. The DMA module maintains a DMA queue for each endpoint
- so multiple DMA requests may be queued and they will complete
- at some future time.
-
- The DMA module must be started before it can be used. It is
- started by calling CyAsDmaStart(). This function initializes
- all of the endpoint data structures.
-
- In order to perform DMA on a particular endpoint, the endpoint
- must be enabled by calling CyAsDmaEnableEndPoint(). In addition
- to enabling or disabling the endpoint, this function also sets
- the direction for a given endpoint. Direction is given in USB
- terms. For P port to West Bridge traffic, the endpoint is a
- CyAsDirectionIn endpoint. For West Bridge to P port traffic,
- the endpoint is a CyAsDirectionOut endpoint.
-
- Once DMA is started and an endpoint is enabled, DMA requests
- are issued by calling CyAsDmaQueueRequest(). This function
- queue either a DMA read or DMA write request. The callback
- associated with the request is called once the request has been
- fulfilled.

-/*@@Hardware Abstraction Layer (HAL)
- Summary
- This software module is supplied by the user of the West Bridge
- API. This module contains the software that is specific to the
- hardware implementation or operating system of the client
- system.
-
- * Sleep Channels *
- A sleep channel is a operating system object that provides that
- capability for one thread or process to sleep while waiting on
- the completion of some hardware event. The hardware event is
- usually processed by a hardware interrupt and the interrupt
- handler then wakes the thread or process that is sleeping.
-
- A sleep channel provides the mechanism for this operation. A
- sleep channel is created and initialized during the API
- initialization. When the API needs to wait for the hardware,
- the API performs a SleepOn() operation on the sleep channel.
- When hardware event occurs, an interrupt handler processes the
- event and then performs a Wake() operation on the sleep channel
- to wake the sleeping process or thread.
-
- * DMA Model *
- When the West Bridge API needs to transfer USB or storage data
- to/from the West Bridge device, this is done using a "DMA"
- operation. In this context the term DMA is used loosely as the
- West Bridge API does not really care if the data is transferred
- using a burst read or write operation, or if the data is
- transferred using programmed I/O operations. When a "DMA"
- operation is needed, the West Bridge API calls either
- CyAsHalDmaSetupRead() or CyAsHalDmaSetupWrite() depending on the
- direction of the data flow. The West Bridge API expects the
- "DMA" operation requested in the call to be completed and the
- registered "DMA complete" callback to be called.
-
- The West Bridge API looks at several factors to determine the
- size of the "DMA" request to pass to the HAL layer. First the
- West Bridge API calls CyAsHalDmaMaxRequestSize() to determine
- the maximum amount of data the HAL layer can accept for a "DMA"
- operation on the requested endpoint. The West Bridge API will
- never exceed this value in a "DMA" request to the HAL layer.
- The West Bridge API also sends the maximum amount of data the
- West Bridge device can accept as part of the "DMA" request. If
- the amount of data in the "DMA" request to the HAL layer
- exceeds the amount of data the West Bridge device can accept,
- it is expected that the HAL layer has the ability to break the
- request into multiple operations.
-
- If the HAL implementation requires the API to handle the size
- of the "DMA" requests for one or more endpoints, the value
- CY_AS_DMA_MAX_SIZE_HW_SIZE can be returned from the
- CyAsHalDmaMaxRequestSize() call. In this case, the API assumes
- that the maximum size of each "DMA" request should be limited
- to the maximum that can be accepted by the endpoint in question.
-
- Notes
- See the <install>/api/hal/scm_kernel/cyashalscm_kernel.c file
- for an example of how the DMA request size can be managed by
- the HAL implementation.
-
- * Interrupt Handling *
- The HAL implementation is required to handle interrupts arriving
- from the West Bridge device, and call the appropriate handlers.
- If the interrupt arriving is one of PLLLOCKINT, PMINT, MBINT or
- MCUINT, the CyAsIntrServiceInterrupt API should be called to
- service the interrupt. If the interrupt arriving is DRQINT, the
- HAL should identify the endpoint corresponding to which the DRQ
- is being generated and perform the read/write transfer from the
- West Bridge. See the <install>/api/hal/scm_kernel/
- cyashalscm_kernel.c or <install>/api/hal/fpga/cyashalfpga.c
- reference HAL implementations for examples.
-
- The HAL implementation can choose to poll the West Bridge
- interrupt status register instead of using interrupts. In this
- case, the polling has to be performed from a different thread/
- task than the one running the APIs. This is required because
- there are API calls that block on the reception of data from the
- West Bridge, which is delivered only through the interrupt
- handlers.
-
- * Required Functions *
- This section defines the types and functions that must be
- supplied in order to provide a complete HAL layer for the
- West Bridge API.
-

- * CyAsHalSleepChannel

-/* Summary
- This is the type that represents a sleep channel

- Description
- A sleep channel is an operating system object that, when a

- sleeps until another thread signals the sleep object. This
- object is generally used when a high level API is called
- and must wait for a response that is supplied in an interrupt
- handler. The thread calling the API is put into a sleep
- state and when the reply arrives via the interrupt handler,
- the interrupt handler wakes the sleeping thread to indicate
- that the expect reply is available.

-/*@@Low Level Communications
-
- Summary
- The low level communications module is responsible for
- communications between the West Bridge device and the P
- port processor. Communications is organized as a series
- of requests and subsequent responses. For each request
- there is a one and only one response. Requests may go
- from the West Bridge device to the P port processor, or
- from the P Port processor to the West Bridge device.
-
- Description
- Requests are issued across what is called a context. A
- context is a single channel of communications from one
- processor to another processor. There can be only a single
- request outstanding on a context at a given time. Contexts
- are used to identify subsystems that can only process a
- single request at a time, but are independent of other
- contexts in the system. For instance, there is a context
- for communicating storage commands from the P port processor
- to the West Bridge device. There is also a context for
- communicating USB commands from the P port processor to the
- West Bridge device.
-
- Requests and responses are identical with the exception of
- the type bit in the request/response header. If the type
- bit is one, the packet is a request. If this bit is zero,
- the packet is a response. Also encoded within the header of
- the request/response is the code. The code is a command
- code for a request, or a response code for a response. For
- a request, the code is a function of the context. The code
- 0 has one meaning for the storage context and a different
- meaning for the USB context. The code is treated differently
- in the response. If the code in the response is less than 16,
- then the meaning of the response is global across all
- contexts. If the response is greater than or equal to 16,
- then the response is specific to the associated context.
-
- Requests and responses are transferred between processors
- through the mailbox registers. It may take one or more cycles
- to transmit a complete request or response. The context is
- encoded into each cycle of the transfer to insure the
- receiving processor can route the data to the appropriate
- context for processing. In this way, the traffic from multiple
- contexts can be multiplexed into a single data stream through
- the mailbox registers by the sending processor, and
- demultiplexed from the mailbox registers by the receiving
- processor.
-
- * Firmware Assumptions *
- The firmware assumes that mailbox contents will be consumed
- immediately. Therefore for multi-cycle packets, the data is
- sent in a tight polling loop from the firmware. This implies
- that the data must be read from the mailbox register on the P
- port side and processed immediately or performance of the
- firmware will suffer. In order to insure this is the case,
- the data from the mailboxes is read and stored immediately
- in a per context buffer. This occurs until the entire packet
- is received at which time the request packet is processed.
- Since the protocol is designed to allow for only one
- outstanding packet at a time, the firmware can never be in a
- position of waiting on the mailbox registers while the P port
- is processing a request. Only after the response to the
- previous request is sent will another request be sent.

-/*@@Media Transfer Protocol (MTP) Overview
- Summary
- The MTP API has been designed to allow MTP enabled West Bridge
- devices to implement the MTP protocol while maintaining high
- performance. West Bridge has the capability to enter into a
- Turbo mode during a MTP SendObject or GetObject operation
- enabling it to directly stream the data into or out of the
- attached SD card with minimal involvement from the Processor.
-
- Description
- The MTP API is designed to act as a pass through implementation
- of the MTP protocol for all operations. Each MTP transaction
- received from the Host is passed through West Bridge and along
- to the Processor. The Processor can then respond to the
- transaction and pass data and/or responses back to the Host
- through West Bridge.
-
- The MTP API also allows for a high speed handling of MTP
- SendObject and GetObject operations, referred to as Turbo MTP.
- During a Turbo MTP operation West Bridge is responsible for
- reading or writing the data for the MTP operation directly from
- or to the SD card with minimal interaction from the Processor.
- The is done by having the Processor transfer a Block Table
- to West Bridge which contains the locations on the SD card that
- need to be read or written. During the handling of a Turbo
- Operation the Processor will then only periodically need to
- send a new Block Table to West Bridge when the first is used up.
- See the CyAsMTPInitSendObject and CyAsMTPInitGetObject functions
- for more details.
-
- In order to enable the MTP API you must first have a MTP enabled
- West Bridge loaded with MTP firmware. You then must start the USB
- and Storage APIs before starting the MTP API. See CyAsMTPStart
- for more details.
-*/
-
-/*@@Endpoints
- Summary
- When using MTP firmware endpoints 2 and 6 are dedicated
- to bulk MTP traffic and endpoint 1 is available for MTP
- events.
-
- Description
- When using a MTP enabled West Brdige device endpoints 2 and
- 6 are made available for use to implement the MTP protocol.
- These endpoints have a few special restrictions noted below
- but otherwise the existing USB APIs can be used normally with
- these endpoints.
-
- 1. CyAsUsbSetNak, CyAsUsbClearNak, and CyAsUsbGetNak are
- disabled for these endpoints

-/*@@Storage APIs
- Summary
- This section documents the storage APIs supported by the
- West Bridge API.
-
- Description
- The storage API is based on some specific concepts which
- are referenced here.
- * <LINK Storage API Overview>
- * Addressing
- * Ownership
- * <LINK Asynchronous Versus Synchronous Operation>
-*/
-
-/*@@Storage API Overview
- Summary
- Storage devices are identified by media type. Each media
- type is considered a single logical device.
-
- Description
- Each media type has a consistent block size and consists
- of a set of logical blocks numbered from 0 to N - 1 where
- N is the size of the
- media type in blocks. The mass storage APIs defined below
- provide the
- capability to query for devices that are present, and
- read/write data to/from
- these devices.
-*/
-
-/*@@Addressing
- Summary
- Blocks within a storage device are address by a hierarchal
- block address. This
- address consists of the bus number, physical device,
- logical unit, and finally
- block address.
-
- Description
- While currently only a single device of each media type
- is supported, the address
- space reserves space in the future for multiple devices
- of each type. Therefore
- the second element of the address is the specific device
- being addressed within
- a given device type. For this release of the software,
- this value will always be
- zero to address the first device.
-
- The third element of the address is the logical unit.
- A device being managed
- by West Bridge can be partitioned into multiple logical
- units. This partition
- information is stored on each device itself. Currently,
- one of the storage devices
- managed by West Bridge can be partitioned into two
- logical units.
-
- Finally a logical block address is given within the
- logical unit to address an
- individual block.
-*/
-
-/*@@Ownership
- Summary
- While West Bridge supports concurrent block level
- operations from both the USB port and
- the processor port, this is not desirable in most
- situations as the file system
- contained on the storage media cannot be accessed
- concurrently. To insure access
- by only one of USB and the processor, the West Bridge
- API provides for ownership of storage
- devices based on media type.
-
- Description
- The processor requests ownership of a given media type
- by calling CyAsStorageClaim().
- The firmware in West Bridge releases control of the
- media and signals the processor through
- the event callback registered with
- CyAsStorageRegisterCallback(). The specific event is
- the CyAsStorageProcessor. The processor can later
- release the media via a call to
- CyAsStorageRelease(). This call is immediate and
- no callback is required.
-
- If the processor has claimed storage and the USB port
- is connected, West Bridge will need to
- claim the storage to manage the mass storage device.
- West Bridge requests the storage through
- the event callback registered with
- CyAsStorageRegisterCallback(). The specific event is
- CyAsStorageAntioch and is named as such to reflect
- the USB view of storage. This callback
- is a request for the processor to release storage.
- The storage is not actually released
- until the processor calls CyAsStorageRelease().
-
- Note that the CyAsStorageAntioch is only sent when the
- USB storage device is enumerated and
- NOT at every USB operation. The ownership of a given
- storage media type is assumed to belong
- to the processor until the USB connection is established.
- At that point, the storage ownership
- is transferred to West Bridge. After the USB connection
- is broken, ownership can be transferred
- back to the processor.
-*/
-
-/*@@Asynchronous Versus Synchronous Operation
- Summary
- When read or write operations are performed to the
- storage devices, these operations may be
- synchronous or asynchronous. A synchronous operation
- is an operation where the read or write
- operation is requested and the function does not return
- until the operation is complete. This
- type of function is the easiest to use but does not
- provide for optimal usage of the P port processor time.
-
- Description
- An asynchronous operation is one where the function returns
- as soon as the request is started.
- The specific read and write request will complete at some
- time in the future and the P port
- processor will be notified via a callback function. While
- asynchronous functions provide for
- much better usage of the CPU, these function have more
- stringent requirements for use. First,
- any buffer use for data transfer must be valid from the
- function call to request the operation
- through when the callback function is called. This basically
- implies that stack based buffers
- are not acceptable for asynchronous calls. Second, error
- handling must be deferred until the
- callback function is called indicating any kind of error
- that may have occurred.
-*/
-
-/*@@Partitioning
- Summary
- West Bridge API and firmware support the creation of up to
- two logical partitions on one
- of the storage devices that are managed by West Bridge. The
- partitions are managed through
- the CyAsStorageCreatePPartition and CyAsStorageRemovePPartition
- APIs.
-
- Description
- The CyAsStorageCreatePPartition API is used to divide the total
- storage on a storage
- device into two logical units or partitions. Since the partition
- information is stored
- on the storage device in a custom format, partitions should
- only be created on fixed
- storage devices (i.e., no removable SD/MMC cards). Any data
- stored on the device
- before the creation of the partition, is liable to be lost when
- a partition is created.
-
- The CyAsStorageRemovePPartition API is used to remove the
- stored partition information,
- so that all of the device's capacity is treated as a single
- partition again.
-
- When a storage device with two partitions (units) is being
- enumerated as a mass storage
- device through the West Bridge, it is possible to select the
- partitions to be made
- visible to the USB host. This is done through the
- CyAsUsbSelectMSPartitions API.

-
-/* Summary
- This constants indicates a raw device access to the read/write
- functions
-
- Description
- When performing reading and writing operations on the
- storage devices attached
- to West Bridge, there are cases where writes need to
- happen to raw devices, versus
- the units contained within a device. This is
- specifically required to manage
- the partitions within physical devices. This constant
- is used in calls to
- CyAsStorageRead(), CyAsStorageReadAsync(),
- CyAsStorageWrite() and
- CyAsStorageWriteAsync(), to indicate that the raw
- physical device is being
- accessed and not any specific unit on the device.

-/*@@Enumeration Model
- Summary
- The USB enumeration process is the process of communicating
- to the USB host information
- about the capabilities of the connected device. This
- process is completed by servicing
- requests for various types of descriptors. In the software
- APIs described below, this
- process is controlled in one of two ways.
-
- Description
- There are advantages to either type of enumeration
- and this is why both models are supported.
- P Port processor based enumeraton gives the P port
- processor maximum control and flexibility
- for providing USB configuration information. However,
- this does require (near) real time data
- responses from the P port processor during the enumeration
- process. West Bridge based enumeration
- requires no real time information from the P port processor,
- ensuring the fastest possible
- enumeration times.
-
- * P Port Based Enumeration *
- The first method for handling USB enumeration is for the
- processor client to handle all
- endpoint zero requests for descriptors. This mode is
- configured by indicating to the API
- that the processor wants to handle all endpoint zero
- requests. This is done by setting
- bit 0 in the end_point_mask to a 1. The processor uses
- CyAsUsbReadDataAsync() to read the request and
- CyAsUsbWriteDataAsync() to write the response.
-
- * West Bridge Based Enumeration *
- The second method for handling USB enumeration is the
- configuration information method.
- Before enabling a connection from the West Bridge device
- to the USB connector, the P Port
- processor sends information about the USB configuration to
- West Bridge through the configuration
- APIs. This information is stored within the West Bridge
- device. When a USB cable is attached,
- the West Bridge device then handles all descriptor requests
- based on the stored information.
- Note that this method of enumeration only supports a single
- USB configuration.
-
- In either model of enumeration, the processor client is
- responsible for ensuring that
- the system meets USB Chapter 9 compliance requirements. This
- can be done by providing spec
- compliant descriptors, and handling any setup packets that
- are sent to the client
- appropriately.
-
- Mass storage class compliance will be ensured by the West
- Bridge firmware when the mass
- storage functionality is enabled.
-*/
-
-/*@@Endpoint Configuration
- Summary
- The West Bridge device has one 64-byte control endpoint, one
- 64-byte low bandwidth endpoint, four bulk
- endpoints dedicated for mass storage usage, and up to ten
- bulk/interrupt/isochronous
- endpoints that can be used for USB-to-Processor communication.
-
- Description
- The four storage endpoints (Endpoints 2, 4, 6 and 8) are
- reserved for accessing storage
- devices attached to West Bridge and are not available for use
- by the processor. These are
- used implicitly when using the storage API to read/write to
- the storage media.
-
- Endpoint 0 is the standard USB control pipe used for all
- enumeration activity. Though
- the endpoint buffer is not directly accessible from the
- processor, read/write activity
- can be performed on this endpoint through the API layers.
- This endpoint is always
- configured as a bi-directional control endpoint.
-
- Endpoint 1 is a 64-byte endpoint that can be used for low
- bandwidth bulk/interrupt
- activity. The physical buffer is not accessible from the
- processor, but can be read/written
- through the API. As the data coming to this endpoint is
- being handled through the
- software layers, there can be loss of data if a read call
- is not waiting when an OUT
- packet arrives.
-
- Endpoints 3, 5, 7, 9, 10, 11, 12, 13, 14 and 15 are ten
- configurable endpoints
- mapped to parts of a total 4 KB FIFO buffer space on the
- West Bridge device. This 4 KB
- physical buffer space is divided into up to four endpoints
- called PEP1, PEP2, PEP3 and PEP4
- in this software document. There are multiple configurations
- in which this buffer space
- can be used, and the size and number of buffers available to
- each physical endpoint
- vary between these configurations. See the West Bridge PDD
- for details on the buffer
- orientation corresponding to each configuration.
-
- * Note *
- PEPs 1, 2, 3 and 4 are called Physical EP 3, 5, 7 and 9 in the
- West Bridge PDD. The
- sequential number scheme is used in the software to disambiguate
- these from the logical
- endpoint numbers, and also for convenience of array indexing.

-/* Summary
- This data structure is the data passed via the evdata paramater
- on a usb event callback for the inquiry request.
-
- Description
- When a SCSI inquiry request arrives via the USB connection and
- the P Port has asked
- to receive inquiry requests, this request is forwarded to the
- client via the USB
- callback. This callback is called twice, once before the
- inquiry data is forwarded
- to the host (CyAsEventUsbInquiryBefore) and once after the
- inquiry has been sent to the
- USB host (CyAsEventUsbInquiryAfter). The evdata parameter
- is a pointer to this data
- structure.
-
- *CyAsEventUsbInquiryBefore*
- If the client just wishes to see the inquiry request and
- associated data, then a simple
- return from the callback will forward the inquiry response
- to the USB host. If the
- client wishes to change the data returned to the USB host,
- the updated parameter must
- be set to CyTrue and the memory area address by the data
- parameter should be updated.
- The data pointer can be changed to point to a new memory
- area and the length field
- changed to change the amount of data returned from the
- inquiry request. Note that the
- data area pointed to by the data parameter must remain
- valid and the contents must
- remain consistent until after the CyAsEventUsbInquiryAfter
- event has occurred. THE LENGTH
- MUST BE LESS THAN 192 BYTES OR THE CUSTOM INQUIRY RESPONSE
- WILL NOT BE RETURNED. If the
- length is too long, the default inquiry response will be
- returned.
-
- *CyAsEventUsbInquiryAfter*
