Staging: add West Bridge Astoria Driver

This is a driver for the Cypress West Bridge companion chip. Its
function is analogous to the North/South Bridges of PC environments
applied to embedded devices, in that it expands I/O and storage
capabilities of an embedded processor. The Astoria version, which this
driver applies to, functions as a USB, embedded memory and SDIO
controller. The kernel that this patch was applied to is linux-2.6.35,
although it was tested using the android kernel 2.6.29 running on the
Zoom 2 platform. In this system, it was used primarily as a sideloading
accelerator enabling direct data transfers between a USB host PC and
embedded memory without system overheads.  Minor modifications were also
made to the kernel for this patch. These include changes such as
EXPORTing of fat_get_block in the kernel code. Another function,
mpage_cleardirty was also added to the memory management code. This
function is used to clear the dirty pages from a specific inode. This
allows for direct, file based DMA. None of these changes are believed to
have any negative impact on the kernel and may provide additional
benefit for other developers and drivers.

The driver, as submitted, was placed into the drivers/staging/westbridge
folder as the directory structure it will eventually reside in is not yet
defined. The driver, as placed in staging is divided into four parts:
1) gadget - this implements a gadget peripheral controller and includes IOCTLs
for MTP transfers
2) block -this implements a generic block device driver to enable access to
embedded memory
3) api -this is the Cypress SDK, and includes USB and Storage specific
functions. In addition, it includes common code for low level routines such as
message passing and common data transfer routines
4) hal - this should likely be included in the arch directory as it needs to
be modified for a given platform. The directory structure in the staging area
is meant to reflect the eventual location of where this code likely should be.
It is platform specific. In this case, the HAL included is for the Android
Zoom 2 platform. Here, West Bridge is connected to the GPMC (general purpose
memory controller) of the OMAP3. Specific timing needs to be enabled to ensure
reliable communication.

+ * 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.

+/*@@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 intializes
+	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.

+/*@@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.

+
+   There are two methods of placing the device in standby mode.  If the
+   WAKEUP pin of the West Bridge is connected to a GPIO on the processor,
+   the pin is de-asserted (via the HAL layer) and West Bridge enters into

+/*@@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.

+  When using a MTP enabled West Brdige device endpoints 2 and
+  6 are made available for use to implement the MTP protocol.

+  Summary

+
+  Description
+  The storage API is based on some specific concepts which
+  are referenced here.

+  * <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.

+/*@@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*
+   If the client needs to free any data, this event signals that
+   the data associated with the inquiry is no longer needed.

+
+   Description
+   West Bridge firmware supports the creation of upto two
+   partitions on mass storage devices connected to the West Bridge
+   device.  When there are two partitions on a device, the user can
+   choose which of these partitions should be made visible to the
+   USB host through the USB mass storage interface.  This function
+   allows the user to configure the partitions that should be
+   enumerated.  At least one partition should be selected through
+   this API.  If neither partition needs to be enumerated, use
+   CyAsUsbSetEnumConfig to control this.
+
+   * Valid in Asynchronous callback: Yes (if cb supplied)
