Log message:
* 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
