        * cdl/io_can.cdl: support for add/remove compiler flags
        * doc/can.sgml, doc/can_driver_doc.html: updated doc reflecting API
        changes (range/mask filtering, listen-only mode, return values for
        xmt_msg/rcv_event, new flags).
        * include/can.h: given in a match the types of function pointers for
        can_callbacks_t according to the changes made in can.c.
        * include/canio.h: flags field in event enlarged to 32 bits to fit
        new events 'CYGNUM_CAN_EVENT_ERR_ACTIVE' and
        'CYGNUM_CAN_EVENT_OVERRUN_RX_HW'. Made a 'flag' typedef.
        cyg_can_event fields reordered so flags size change keeps events the
        same size.  Defined new filtering capabilities (range/mask). New
        convenience macro CYGNUM_CAN_EVENT_ALL. New listen-only mode.
        * src/can.c: can_rcv_event() and can_xmt_msg() now returns cyg_bool
        (were 'void'). flags using cyg_can_event_flags_t type.

        * include/can.h: EOF footer: s/SERIAL/CAN/.
        * src/can.c: can_set_config(): Fixed key's name to drain output:
        s{CYG_IO_GET_CONFIG_SERIAL_OUTPUT_DRAIN
        }{CYG_IO_SET_CONFIG_CAN_OUTPUT_DRAIN}.

        * doc/can.sgml: Callback on event documentation.
        * src/can.c:  Change one wakeup to callback in a comment.
        * include/canio.h: changed cyg_addrword_t to CYG_ADDRWORD so
          can will compile without the kernel.

           Andrew Lunn <andrew.lunn@ascom.ch>
        
        * cdl/io_can.cdl: Added option CYGOPT_IO_CAN_SUPPORT_CALLBACK
      
        * include/canio.h: Added struct cyg_can_callback_cfg for setting
          callback configurations.
       
        * include/can.h: Added declaration and initialization of callback 
          configuration in struct can_channel.
       
        * src/can.c: Added callback configuration changing and
          application function call.

2007-07-02 Uwe Kindler <uwe_kindler@web.de>
    
        * cdl/io_can.cdl: Added interface CYGINT_IO_CAN_CHANNELS for
          counting available CAN channels
      
        * include/canio.h: Changed type cyg_can_msgbuf_info. The two
          fields are 16 bit now because device drivers may support more
          than 256 message buffers (i.e. the LPC2xxx CAN driver)
    
2007-06-20  Uwe Kindler  <uwe_kindler@web.de>

        * test/can_filter: Changed filter loop counter from cyg_uint8 to
          cyg_uint16 because LPC2xxx CAN driver supports more than 256
          message buffers.

2007-03-23  Uwe Kindler  <uwe_kindler@web.de>

        * cdl/io_can.cdl: Added several interfaces for implementation by
          device drivers.
          Moved several configuration options from device drivers to the
          generic CAN driver. With this design a device driver does not
          need to provide all configuration options in its CDL file - it
          simply needs to implement the provided interfaces. The drawback
          of this decicsion is, that it is not possible to control these
          options independently for several CAN devices. (But most platforms
          will have only 1 channel)
          Added configuration option CYGBLD_IO_CAN_EXTRA_TESTS. This option
          enables the build of the interactive CAN tests.
          
        * test/can_filter: Added interactive message filtering test
        
        * test/can_hdi: Added interactive hardware description interface
          test
          
        * test/can_load: Added interactive message handling (reception,
          transmission) test.
          
        * test/can_remote: Added interactive remote response buffer test
          
        * test/can_tx: Added interactive basic TX test. All tests are not
          part of the eCos test framework because they are interactive. That
          means, they require interaction with another user controlled 
          CAN node.
          
        * include/can.h: Added identifier masks for standard and extended
          identifiers.
          Added the line #include CYGDAT_IO_CAN_DEVICE_INL. This enables a
          device driver to provide an own device inline file. In this inline
          file the driver may define own data types for CAN messages (for
          internal storage of CAN messages (see AT91SAM7 CAN driver))

        * include/canio.h: Added baudrate CYGNUM_CAN_KBAUD_AUTO - support of 
          automatic baudrate detection if a driver supports such a feature.
          Added state CYGNUM_CAN_STATE_CONFIG and mode CYGNUM_CAN_MODE_CONFIG.
          The application may use these identifiers to set the CAN device into
          a state where it is safe to add/remove/configure message buffers.
          Added union data type cyg_can_msg_data. With this data type a 4 byte
          alignment of message data is guaranteed, an byte, word and dword 
          access to the data is possible and an assignment of two CAN datas are
          possible now.
          cyg_can_message now uses cyg_can_msg_data union for CAN data.
          Replaced SW-Filt flag by autobaud flag in HDI.
          Added CAN message access macros for read/write acces of CAN message
          structures. These macros hide implementation of CAN message from 
          application.
 
        * src/can.c: Added support for device driver defined CAN message 
          data types

2006-12-19  Sergei Gavrikov  <sg@sgs.gomel.by>

        * doc/can.sgml: Correctly close para tag.

2006-12-13  Uwe Kindler  <uwe_kindler@web.de>

        * doc/can.sgml: CAN driver SGML documentation added.

2006-08-25  Gary Thomas  <gary@mlbassoc.com>

        * cdl/io_can.cdl: Set parent for more intuitive ConfigTool layout.

2006-03-27  Uwe Kindler  <uwe_kindler@web.de>

        * src/can.c can_rcv_event() Clear the flag field in new event before
        calling into low level hardware driver.

2006-02-15  Uwe Kindler  <uwe_kindler@web.de>

        * include/can_io.h Added message buffer configuration identifier:
        CYGNUM_CAN_MSGBUF_RESET_ALL, CYGNUM_CAN_MSGBUF_RX_FILTER_ALL ...
        Added cfg_id field to cyg_can_msgbuf_cfg data structure.

2005-09-11  Uwe Kindler  <uwe_kindler@web.de>

        * include/can_io.h Added support for get_config to CAN_LOWLEVEL_FUNS
        structure. 
        Added additional CAN events. 
        Added support for can state (cyg_can_state) and CAN mode (cyg_can_mode).  
        Changed data type of cyg_can_buf_info_t data structure from cyg_int32 
        to cyg_uint32. 
        Added support for message box configuration (cyg_can_msgbuf_info).
        Added support for message filtering (cyg_cn_filter). 
        Renamed cyg_can_rtr_buf to cyg_can_remote_buf. 
        Renamed CYGNUM_CAN_RTR_BUF_NA and CYGNUM_CAN_RTR_BUF_INIT to 
        CYGNUM_CAN_MSGBUF_NA and CYGNUM_CAN_MSGBUF_INIT because they are
        also used for message filtering. 
        Added support for hardware description interface. 
        Added support for CYG_IO_SET_CONFIG_CAN_INPUT_FLUSH,
        CYG_IO_SET_CONFIG_CAN_OUTPUT_FLUSH and CYG_IO_GET_CONFIG_SERIAL_OUTPUT_DRAIN.
        
        * doc/can_driver_doc.html Additional configuration options
        documented.

        * Generic CAN driver package created
