/*@@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.

/*********************************
 * West Bridge Constants
 **********************************/

/* 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.

*/
#define CY_AS_LUN_PHYSICAL_DEVICE (0xffffffff)

/* Summary
   This constant represents the maximum DMA burst length
   supported on a storage endpoint

   Description
   West Bridge reserves separate endpoints for accessing
   storage media through the
   CyAsStorageRead() and CyAsStorageWrite() calls. The
   maximum size of these
   endpoints is always 512 bytes, regardless of status
   and speed of the USB

/* Summary
   This function is used to register a callback function
   for the storage API.

   Description
   At times West Bridge needs to inform the P port processor
   of events that have occurred.  These events are asynchronous
   to the thread of control on the P
   port processor and as such are generally delivered via a
   callback function that
   is called as part of an interrupt handler.  This function
   registers the callback
   function that is called when an event occurs.  Each call
   to this function
   replaces any old callback function with a new callback
   function supplied on
   the most recent call.  This function can also be called
   with a callback function
   of NULL in order to remove any existing callback function

   * Valid In Asynchronous Callback:YES

   Returns

   This function claims a given media type.

   Description
   This function communicates to West Bridge that the
