Staging: delete westbridge code
It's been stagnant for a while with out much forward progress for a variety of different reasons. So remove it for now. It can be reverted at any time if development picks back up again. Acked-by: David Cross <odc@cypress.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

23* Storage Design
24*
25* The storage module is fairly straight forward once the
26* DMA and LOWLEVEL modules have been designed. The
27* storage module simple takes requests from the user, queues
28* the associated DMA requests for action, and then sends
29* the low level requests to the West Bridge firmware.

25/* Summary
26 * If set to TRUE, the basic numeric types are defined by the
27 * West Bridge API code
28 *
29 * Description
30 * The West Bridge API relies on some basic integral types to be
31 * defined. These types include uint8_t, int8_t, uint16_t,
32 * int16_t, uint32_t, and int32_t. If this macro is defined the
33 * West Bridge API will define these types based on some basic
34 * assumptions. If this value is set and the West Bridge API is
35 * used to set these types, the definition of these types must be
36 * examined to insure that they are appropriate for the given
37 * target architecture and compiler.
38 *
39 * Notes
40 * It is preferred that if the basic platform development
41 * environment defines these types that the CY_DEFINE_BASIC_TYPES
42 * macro be undefined and the appropriate target system header file
43 * be added to the file cyashaldef.h.

1029 This function finds the device object given the HAL tag
1030
1031 Description
1032 The user associats a device TAG with each West Bridge device
1033 created. This tag is passed from the API functions to and HAL
1034 functions that need to ID a specific West Bridge device. This
1035 tag is also passed in from the user back into the API via
1036 interrupt functions. This function allows the API to find the
1037 device structure associated with a given tag.
1038
1039 Notes
1040 This function does a simple linear search for the device based
1041 on the TAG. This function is called each time an West Bridge
1042 interrupt handler is called. Therefore this works fine for a
1043 small number of West Bridge devices (e.g. less than five).
1044 Anything more than this and this methodology will need to be
1045 updated.

31/*@@DMA Overview
32 This module manages the DMA operations to/from the West Bridge
33 device. The DMA module maintains a DMA queue for each endpoint
34 so multiple DMA requests may be queued and they will complete
35 at some future time.
36
37 The DMA module must be started before it can be used. It is
38 started by calling CyAsDmaStart(). This function initializes
39 all of the endpoint data structures.
40
41 In order to perform DMA on a particular endpoint, the endpoint
42 must be enabled by calling CyAsDmaEnableEndPoint(). In addition
43 to enabling or disabling the endpoint, this function also sets
44 the direction for a given endpoint. Direction is given in USB
45 terms. For P port to West Bridge traffic, the endpoint is a
46 CyAsDirectionIn endpoint. For West Bridge to P port traffic,
47 the endpoint is a CyAsDirectionOut endpoint.
48
49 Once DMA is started and an endpoint is enabled, DMA requests
50 are issued by calling CyAsDmaQueueRequest(). This function
51 queue either a DMA read or DMA write request. The callback
52 associated with the request is called once the request has been
53 fulfilled.

27/*@@Hardware Abstraction Layer (HAL)
28 Summary
29 This software module is supplied by the user of the West Bridge
30 API. This module contains the software that is specific to the
31 hardware implementation or operating system of the client
32 system.
33
34 * Sleep Channels *
35 A sleep channel is a operating system object that provides that
36 capability for one thread or process to sleep while waiting on
37 the completion of some hardware event. The hardware event is
38 usually processed by a hardware interrupt and the interrupt
39 handler then wakes the thread or process that is sleeping.
40
41 A sleep channel provides the mechanism for this operation. A
42 sleep channel is created and initialized during the API
43 initialization. When the API needs to wait for the hardware,
44 the API performs a SleepOn() operation on the sleep channel.
45 When hardware event occurs, an interrupt handler processes the
46 event and then performs a Wake() operation on the sleep channel
47 to wake the sleeping process or thread.
48
49 * DMA Model *
50 When the West Bridge API needs to transfer USB or storage data
51 to/from the West Bridge device, this is done using a "DMA"
52 operation. In this context the term DMA is used loosely as the
53 West Bridge API does not really care if the data is transferred
54 using a burst read or write operation, or if the data is
55 transferred using programmed I/O operations. When a "DMA"
56 operation is needed, the West Bridge API calls either
57 CyAsHalDmaSetupRead() or CyAsHalDmaSetupWrite() depending on the
58 direction of the data flow. The West Bridge API expects the
59 "DMA" operation requested in the call to be completed and the
60 registered "DMA complete" callback to be called.
61
62 The West Bridge API looks at several factors to determine the
63 size of the "DMA" request to pass to the HAL layer. First the
64 West Bridge API calls CyAsHalDmaMaxRequestSize() to determine
65 the maximum amount of data the HAL layer can accept for a "DMA"
66 operation on the requested endpoint. The West Bridge API will
67 never exceed this value in a "DMA" request to the HAL layer.
68 The West Bridge API also sends the maximum amount of data the
69 West Bridge device can accept as part of the "DMA" request. If
70 the amount of data in the "DMA" request to the HAL layer
71 exceeds the amount of data the West Bridge device can accept,
72 it is expected that the HAL layer has the ability to break the
73 request into multiple operations.
74
75 If the HAL implementation requires the API to handle the size
76 of the "DMA" requests for one or more endpoints, the value
77 CY_AS_DMA_MAX_SIZE_HW_SIZE can be returned from the
78 CyAsHalDmaMaxRequestSize() call. In this case, the API assumes
79 that the maximum size of each "DMA" request should be limited
80 to the maximum that can be accepted by the endpoint in question.
81
82 Notes
83 See the <install>/api/hal/scm_kernel/cyashalscm_kernel.c file
84 for an example of how the DMA request size can be managed by
85 the HAL implementation.
86
87 * Interrupt Handling *
88 The HAL implementation is required to handle interrupts arriving
89 from the West Bridge device, and call the appropriate handlers.
90 If the interrupt arriving is one of PLLLOCKINT, PMINT, MBINT or
91 MCUINT, the CyAsIntrServiceInterrupt API should be called to
92 service the interrupt. If the interrupt arriving is DRQINT, the
93 HAL should identify the endpoint corresponding to which the DRQ
94 is being generated and perform the read/write transfer from the
95 West Bridge. See the <install>/api/hal/scm_kernel/
96 cyashalscm_kernel.c or <install>/api/hal/fpga/cyashalfpga.c
97 reference HAL implementations for examples.
98
99 The HAL implementation can choose to poll the West Bridge
100 interrupt status register instead of using interrupts. In this
101 case, the polling has to be performed from a different thread/
102 task than the one running the APIs. This is required because
103 there are API calls that block on the reception of data from the
104 West Bridge, which is delivered only through the interrupt
105 handlers.
106
107 * Required Functions *
108 This section defines the types and functions that must be
109 supplied in order to provide a complete HAL layer for the

151 Description
152 A sleep channel is an operating system object that, when a
153 thread of control waits on the sleep channel, the thread
154 sleeps until another thread signals the sleep object. This
155 object is generally used when a high level API is called
156 and must wait for a response that is supplied in an interrupt
157 handler. The thread calling the API is put into a sleep
158 state and when the reply arrives via the interrupt handler,
159 the interrupt handler wakes the sleeping thread to indicate
160 that the expect reply is available.

25/*@@Low Level Communications
26
27 Summary
28 The low level communications module is responsible for
29 communications between the West Bridge device and the P
30 port processor. Communications is organized as a series
31 of requests and subsequent responses. For each request
32 there is a one and only one response. Requests may go
33 from the West Bridge device to the P port processor, or
34 from the P Port processor to the West Bridge device.
35
36 Description
37 Requests are issued across what is called a context. A
38 context is a single channel of communications from one
39 processor to another processor. There can be only a single
40 request outstanding on a context at a given time. Contexts
41 are used to identify subsystems that can only process a
42 single request at a time, but are independent of other
43 contexts in the system. For instance, there is a context
44 for communicating storage commands from the P port processor
45 to the West Bridge device. There is also a context for
46 communicating USB commands from the P port processor to the
47 West Bridge device.
48
49 Requests and responses are identical with the exception of
50 the type bit in the request/response header. If the type
51 bit is one, the packet is a request. If this bit is zero,
52 the packet is a response. Also encoded within the header of
53 the request/response is the code. The code is a command
54 code for a request, or a response code for a response. For
55 a request, the code is a function of the context. The code
56 0 has one meaning for the storage context and a different
57 meaning for the USB context. The code is treated differently
58 in the response. If the code in the response is less than 16,
59 then the meaning of the response is global across all
60 contexts. If the response is greater than or equal to 16,
61 then the response is specific to the associated context.
62
63 Requests and responses are transferred between processors
64 through the mailbox registers. It may take one or more cycles
65 to transmit a complete request or response. The context is
66 encoded into each cycle of the transfer to insure the
67 receiving processor can route the data to the appropriate
68 context for processing. In this way, the traffic from multiple
69 contexts can be multiplexed into a single data stream through
70 the mailbox registers by the sending processor, and
71 demultiplexed from the mailbox registers by the receiving
72 processor.
73
74 * Firmware Assumptions *
75 The firmware assumes that mailbox contents will be consumed
76 immediately. Therefore for multi-cycle packets, the data is
77 sent in a tight polling loop from the firmware. This implies
78 that the data must be read from the mailbox register on the P
79 port side and processed immediately or performance of the
80 firmware will suffer. In order to insure this is the case,
81 the data from the mailboxes is read and stored immediately
82 in a per context buffer. This occurs until the entire packet
83 is received at which time the request packet is processed.
84 Since the protocol is designed to allow for only one
85 outstanding packet at a time, the firmware can never be in a
86 position of waiting on the mailbox registers while the P port
87 is processing a request. Only after the response to the
88 previous request is sent will another request be sent.

131 Description
132 When the West Bridge device is reset, there are two types of
133 reset that arE possible. This type indicates the type of reset
134 requested.

136 Notes
137 Both of these reset types are software based resets; and are
138 distinct from a chip level HARD reset that is applied through
139 the reset pin on the West Bridge.
140
141 The CyAsResetSoft type resets only the on-chip micro-controller
142 in the West Bridge. In this case, the previously loaded firmware
143 will continue running. However, the Storage and USB stack
144 operations will need to be restarted, as any state relating to
145 these would have been lost.
146
147 The CyAsResetHard type resets the entire West Bridge chip, and will
148 need a fresh configuration and firmware download.

967 instructs the West Bridge firmware that the device is about to be
968 placed into sleep mode. This allows West Bridge to complete any pending

971
972 There are two methods of placing the device in standby mode. If the
973 WAKEUP pin of the West Bridge is connected to a GPIO on the processor,
974 the pin is de-asserted (via the HAL layer) and West Bridge enters into
975 a sleep mode. If the WAKEUP pin is not accessible, the processor can
976 write into the power management control/status register on the West
977 Bridge to put the device into sleep mode.

1284 function sets the West Bridge device into this low power mode.
1285 This mode can only be entered when there is no active USB
1286 connection; i.e., when USB has not been connected or is suspended;
1287 and there are no pending USB or storage asynchronous calls. The
1288 device will exit the suspend mode and resume handling USB and
1289 processor requests when any activity is detected on the CE#, D+/D-
1290 or GPIO[0] lines.

29/*@@Media Transfer Protocol (MTP) Overview
30 Summary
31 The MTP API has been designed to allow MTP enabled West Bridge
32 devices to implement the MTP protocol while maintaining high
33 performance. West Bridge has the capability to enter into a
34 Turbo mode during a MTP SendObject or GetObject operation
35 enabling it to directly stream the data into or out of the
36 attached SD card with minimal involvement from the Processor.
37
38 Description
39 The MTP API is designed to act as a pass through implementation
40 of the MTP protocol for all operations. Each MTP transaction
41 received from the Host is passed through West Bridge and along
42 to the Processor. The Processor can then respond to the
43 transaction and pass data and/or responses back to the Host
44 through West Bridge.
45
46 The MTP API also allows for a high speed handling of MTP
47 SendObject and GetObject operations, referred to as Turbo MTP.
48 During a Turbo MTP operation West Bridge is responsible for
49 reading or writing the data for the MTP operation directly from
50 or to the SD card with minimal interaction from the Processor.
51 The is done by having the Processor transfer a Block Table
52 to West Bridge which contains the locations on the SD card that
53 need to be read or written. During the handling of a Turbo
54 Operation the Processor will then only periodically need to
55 send a new Block Table to West Bridge when the first is used up.
56 See the CyAsMTPInitSendObject and CyAsMTPInitGetObject functions
57 for more details.
58
59 In order to enable the MTP API you must first have a MTP enabled
60 West Bridge loaded with MTP firmware. You then must start the USB
61 and Storage APIs before starting the MTP API. See CyAsMTPStart
62 for more details.

266/* Summary
267 This function starts the MTP stack.
268
269 Description
270 Initializes West Bridge for MTP activity and registers the MTP
271 event callback.
272
273 Before calling CyAsMTPStart, CyAsUsbStart and CyAsStorageStart must be
274 called (in either order).
275
276 MTPStart must be called before the device is enumerated. Please
277 see the documentation for CyAsUsbSetEnumConfig and CyAsUsbEnumControl
278 for details on enumerating a device for MTP.
279
280 Calling MTPStart will not affect any ongoing P<->S traffic.
281
282 This requires a MTP firmware image to be loaded on West Bridge.

351 This function sets up a Turbo SendObject operation.
352
353 Description
354 Calling this function will setup West Bridge to
355 enable Tubo handling of the next SendObject
356 operation received. This will pass down the initial
357 block table to the firmware and setup a direct u->s
358 write for the SendObject operation.
359
360 If this function is not called before a SendObject
361 operation is seen the SendObject operation and data
362 will be passed along to the P port like any other MTP
363 command. It would then be the responsibility of the
364 client to perform a normal StorageWrite call to
365 store the data on the SD card. N.B. This will be
366 very slow compared with the Turbo handling.
367
368 The completion of this function only signals that
369 West Bridge has been set up to receive the next SendObject
370 operation. When the SendObject operation has been fully
371 handled and the data written to the SD card a separate

446
447 It is the responsibility of the Processor to send the MTP

449 will then send the data phase of the transaction,
450 automatically creating the required container for Data.
451 Once all of the Data has been transferred a callback will
452 be issued to inform the Processor that the Data phase has
453 completed allowing it to send the required MTP response.

30/*@@Storage APIs
31 Summary
32 This section documents the storage APIs supported by the
33 West Bridge API.

44/*@@Storage API Overview
45 Summary
46 Storage devices are identified by media type. Each media
47 type is considered a single logical device.
48
49 Description
50 Each media type has a consistent block size and consists
51 of a set of logical blocks numbered from 0 to N - 1 where
52 N is the size of the
53 media type in blocks. The mass storage APIs defined below
54 provide the
55 capability to query for devices that are present, and
56 read/write data to/from
57 these devices.
58*/
59
60/*@@Addressing
61 Summary
62 Blocks within a storage device are address by a hierarchal
63 block address. This
64 address consists of the bus number, physical device,
65 logical unit, and finally
66 block address.
67
68 Description
69 While currently only a single device of each media type
70 is supported, the address
71 space reserves space in the future for multiple devices
72 of each type. Therefore
73 the second element of the address is the specific device
74 being addressed within
75 a given device type. For this release of the software,
76 this value will always be
77 zero to address the first device.
78
79 The third element of the address is the logical unit.
80 A device being managed
81 by West Bridge can be partitioned into multiple logical
82 units. This partition
83 information is stored on each device itself. Currently,
84 one of the storage devices
85 managed by West Bridge can be partitioned into two
86 logical units.
87
88 Finally a logical block address is given within the
89 logical unit to address an
90 individual block.
91*/
92
93/*@@Ownership
94 Summary
95 While West Bridge supports concurrent block level
96 operations from both the USB port and
97 the processor port, this is not desirable in most
98 situations as the file system
99 contained on the storage media cannot be accessed
100 concurrently. To insure access
101 by only one of USB and the processor, the West Bridge
102 API provides for ownership of storage
103 devices based on media type.
104
105 Description
106 The processor requests ownership of a given media type
107 by calling CyAsStorageClaim().
108 The firmware in West Bridge releases control of the
109 media and signals the processor through
110 the event callback registered with
111 CyAsStorageRegisterCallback(). The specific event is
112 the CyAsStorageProcessor. The processor can later
113 release the media via a call to
114 CyAsStorageRelease(). This call is immediate and
115 no callback is required.
116
117 If the processor has claimed storage and the USB port
118 is connected, West Bridge will need to
119 claim the storage to manage the mass storage device.
120 West Bridge requests the storage through
121 the event callback registered with
122 CyAsStorageRegisterCallback(). The specific event is
123 CyAsStorageAntioch and is named as such to reflect
124 the USB view of storage. This callback
125 is a request for the processor to release storage.
126 The storage is not actually released
127 until the processor calls CyAsStorageRelease().
128
129 Note that the CyAsStorageAntioch is only sent when the
130 USB storage device is enumerated and
131 NOT at every USB operation. The ownership of a given
132 storage media type is assumed to belong
133 to the processor until the USB connection is established.
134 At that point, the storage ownership
135 is transferred to West Bridge. After the USB connection
136 is broken, ownership can be transferred
137 back to the processor.
138*/
139
140/*@@Asynchronous Versus Synchronous Operation
141 Summary
142 When read or write operations are performed to the
143 storage devices, these operations may be
144 synchronous or asynchronous. A synchronous operation
145 is an operation where the read or write
146 operation is requested and the function does not return
147 until the operation is complete. This
148 type of function is the easiest to use but does not
149 provide for optimal usage of the P port processor time.
150
151 Description
152 An asynchronous operation is one where the function returns
153 as soon as the request is started.
154 The specific read and write request will complete at some
155 time in the future and the P port
156 processor will be notified via a callback function. While
157 asynchronous functions provide for
158 much better usage of the CPU, these function have more
159 stringent requirements for use. First,
160 any buffer use for data transfer must be valid from the
161 function call to request the operation
162 through when the callback function is called. This basically
163 implies that stack based buffers
164 are not acceptable for asynchronous calls. Second, error
165 handling must be deferred until the
166 callback function is called indicating any kind of error
167 that may have occurred.
168*/
169
170/*@@Partitioning
171 Summary
172 West Bridge API and firmware support the creation of up to
173 two logical partitions on one
174 of the storage devices that are managed by West Bridge. The
175 partitions are managed through
176 the CyAsStorageCreatePPartition and CyAsStorageRemovePPartition
177 APIs.
178
179 Description
180 The CyAsStorageCreatePPartition API is used to divide the total
181 storage on a storage
182 device into two logical units or partitions. Since the partition
183 information is stored
184 on the storage device in a custom format, partitions should
185 only be created on fixed
186 storage devices (i.e., no removable SD/MMC cards). Any data
187 stored on the device
188 before the creation of the partition, is liable to be lost when
189 a partition is created.
190
191 The CyAsStorageRemovePPartition API is used to remove the
192 stored partition information,
193 so that all of the device's capacity is treated as a single
194 partition again.
195
196 When a storage device with two partitions (units) is being
197 enumerated as a mass storage
198 device through the West Bridge, it is possible to select the
199 partitions to be made
200 visible to the USB host. This is done through the
201 CyAsUsbSelectMSPartitions API.

212 Description
213 When performing reading and writing operations on the
214 storage devices attached

216 happen to raw devices, versus
217 the units contained within a device. This is
218 specifically required to manage

220 is used in calls to
221 CyAsStorageRead(), CyAsStorageReadAsync(),
222 CyAsStorageWrite() and

224 physical device is being
225 accessed and not any specific unit on the device.

906 This function is used to register a callback function

909 Description
910 At times West Bridge needs to inform the P port processor
911 of events that have occurred. These events are asynchronous
912 to the thread of control on the P
913 port processor and as such are generally delivered via a
914 callback function that
915 is called as part of an interrupt handler. This function
916 registers the callback
917 function that is called when an event occurs. Each call
918 to this function
919 replaces any old callback function with a new callback

29/*@@Enumeration Model
30 Summary
31 The USB enumeration process is the process of communicating
32 to the USB host information
33 about the capabilities of the connected device. This
34 process is completed by servicing
35 requests for various types of descriptors. In the software
36 APIs described below, this
37 process is controlled in one of two ways.
38
39 Description
40 There are advantages to either type of enumeration
41 and this is why both models are supported.
42 P Port processor based enumeraton gives the P port
43 processor maximum control and flexibility
44 for providing USB configuration information. However,
45 this does require (near) real time data
46 responses from the P port processor during the enumeration
47 process. West Bridge based enumeration
48 requires no real time information from the P port processor,
49 ensuring the fastest possible
50 enumeration times.
51
52 * P Port Based Enumeration *
53 The first method for handling USB enumeration is for the
54 processor client to handle all
55 endpoint zero requests for descriptors. This mode is
56 configured by indicating to the API
57 that the processor wants to handle all endpoint zero
58 requests. This is done by setting
59 bit 0 in the end_point_mask to a 1. The processor uses
60 CyAsUsbReadDataAsync() to read the request and
61 CyAsUsbWriteDataAsync() to write the response.
62
63 * West Bridge Based Enumeration *
64 The second method for handling USB enumeration is the
65 configuration information method.
66 Before enabling a connection from the West Bridge device
67 to the USB connector, the P Port
68 processor sends information about the USB configuration to
69 West Bridge through the configuration
70 APIs. This information is stored within the West Bridge
71 device. When a USB cable is attached,
72 the West Bridge device then handles all descriptor requests
73 based on the stored information.
74 Note that this method of enumeration only supports a single
75 USB configuration.
76
77 In either model of enumeration, the processor client is
78 responsible for ensuring that
79 the system meets USB Chapter 9 compliance requirements. This
80 can be done by providing spec
81 compliant descriptors, and handling any setup packets that
82 are sent to the client
83 appropriately.
84
85 Mass storage class compliance will be ensured by the West
86 Bridge firmware when the mass
87 storage functionality is enabled.
88*/
89
90/*@@Endpoint Configuration
91 Summary
92 The West Bridge device has one 64-byte control endpoint, one
93 64-byte low bandwidth endpoint, four bulk
94 endpoints dedicated for mass storage usage, and up to ten
95 bulk/interrupt/isochronous
96 endpoints that can be used for USB-to-Processor communication.
97
98 Description
99 The four storage endpoints (Endpoints 2, 4, 6 and 8) are
100 reserved for accessing storage
101 devices attached to West Bridge and are not available for use
102 by the processor. These are
103 used implicitly when using the storage API to read/write to
104 the storage media.
105
106 Endpoint 0 is the standard USB control pipe used for all
107 enumeration activity. Though
108 the endpoint buffer is not directly accessible from the
109 processor, read/write activity
110 can be performed on this endpoint through the API layers.
111 This endpoint is always
112 configured as a bi-directional control endpoint.
113
114 Endpoint 1 is a 64-byte endpoint that can be used for low
115 bandwidth bulk/interrupt
116 activity. The physical buffer is not accessible from the
117 processor, but can be read/written
118 through the API. As the data coming to this endpoint is
119 being handled through the
120 software layers, there can be loss of data if a read call
121 is not waiting when an OUT
122 packet arrives.
123
124 Endpoints 3, 5, 7, 9, 10, 11, 12, 13, 14 and 15 are ten
125 configurable endpoints
126 mapped to parts of a total 4 KB FIFO buffer space on the
127 West Bridge device. This 4 KB
128 physical buffer space is divided into up to four endpoints
129 called PEP1, PEP2, PEP3 and PEP4
130 in this software document. There are multiple configurations
131 in which this buffer space
132 can be used, and the size and number of buffers available to
133 each physical endpoint
134 vary between these configurations. See the West Bridge PDD
135 for details on the buffer
136 orientation corresponding to each configuration.
137
138 * Note *
139 PEPs 1, 2, 3 and 4 are called Physical EP 3, 5, 7 and 9 in the
140 West Bridge PDD. The
141 sequential number scheme is used in the software to disambiguate
142 these from the logical
143 endpoint numbers, and also for convenience of array indexing.

168 This data structure is the data passed via the evdata paramater
169 on a usb event callback for the inquiry request.
170
171 Description
172 When a SCSI inquiry request arrives via the USB connection and
173 the P Port has asked
174 to receive inquiry requests, this request is forwarded to the
175 client via the USB
176 callback. This callback is called twice, once before the
177 inquiry data is forwarded
178 to the host (CyAsEventUsbInquiryBefore) and once after the
179 inquiry has been sent to the
180 USB host (CyAsEventUsbInquiryAfter). The evdata parameter
181 is a pointer to this data
182 structure.
183
184 *CyAsEventUsbInquiryBefore*
185 If the client just wishes to see the inquiry request and
186 associated data, then a simple
187 return from the callback will forward the inquiry response
188 to the USB host. If the
189 client wishes to change the data returned to the USB host,
190 the updated parameter must
191 be set to CyTrue and the memory area address by the data
192 parameter should be updated.
193 The data pointer can be changed to point to a new memory
194 area and the length field
195 changed to change the amount of data returned from the
196 inquiry request. Note that the
197 data area pointed to by the data parameter must remain
198 valid and the contents must
199 remain consistent until after the CyAsEventUsbInquiryAfter
200 event has occurred. THE LENGTH
201 MUST BE LESS THAN 192 BYTES OR THE CUSTOM INQUIRY RESPONSE
202 WILL NOT BE RETURNED. If the
203 length is too long, the default inquiry response will be
204 returned.
205
206 *CyAsEventUsbInquiryAfter*
207 If the client needs to free any data, this event signals that
208 the data associated with the inquiry is no longer needed.

1064/* Summary
1065 This function sets the configuration of the physical
1066 endpoints into one of the twelve supported configuration
1067
1068 Description
1069 USB endpoints are mapped onto one of four physical
1070 endpoints in the device. Therefore
1071 USB endpoints are known as logical endpoints and these
1072 logical endpoints are mapped to
1073 one of four physical endpoints. In support of these
1074 four physical endpoints there is
1075 four kilo-bytes of buffer spaces that can be used as
1076 buffers for these physical endpoints.
1077 This 4K of buffer space can be configured in one of
1078 twelve ways. This function sets the
1079 buffer configuration for the physical endpoints.

1794 West Bridge firmware supports the creation of up to two
1795 partitions on mass storage devices connected to the West Bridge
1796 device. When there are two partitions on a device, the user can
1797 choose which of these partitions should be made visible to the
1798 USB host through the USB mass storage interface. This function
1799 allows the user to configure the partitions that should be
1800 enumerated. At least one partition should be selected through
1801 this API. If neither partition needs to be enumerated, use
