        cdl/io_disk.cdl: Use CYGPKG_IO as the parent.

2006-09-21  Jonathan Larmour  <jifl@eCosCentric.com>

        * include/disk.h (DISK_CHANNEL): No need for extra _part_dev
        slot intended for entire disk's own devtab.

        * src/disk.c (disk_lookup): Just access pdevs_dev directly
        with no adjusted offset.
        (disk_init): No longer set entry 0 from device devtab.
        It's unnecessary.

2006-09-20  Jonathan Larmour  <jifl@eCosCentric.com>

        * include/disk.h: Merge eCosCentric CVS with public eCos CVS.
        This merges (and therefore changes) the API. ChangeLog
        entries have been incorporated in the correct places below.
        * include/diskio.h: Also merged.
        * cdl/io_disk.cdl: Also merged.
        * src/disk.c: Also merged.

2006-08-18  Andy Jackson  <andy@xylanta.com>

        * cdl/io_disk.cdl: Made debugging CDL controlled. 
        * src/disk.c: Added support to allow non-CHS disk devices to 
        use LBA information in MBR.

2006-02-03  Nick Garnett  <nickg@ecoscentric.com>

        * src/disk.c (read_partition): Switched to favour LBA partition
        information in partition tables. This also means we don't now rely
        on the driver reporting a correct CHS size for the disk.
        (disk_bread, disk_bwrite): API changed to take length in sectors
        rather than bytes. Also call hardware driver to transfer in
        (up to) max_transfer sized chunks, rather than a sector at a
        time. Call in to driver now made with DSR lock claimed, to avoid a
        race condition between the DSR and the calling thread.
        (disk_get_config): Added phys_block_size to channel info.

        * include/diskio.h (struct cyg_disk_identify_t): Added
        phys_block_size and max_transfer fields. These must be filled in
        by the driver.

2005-12-12  Jonathan Larmour  <jifl@eCosCentric.com>

        * include/disk.h (DISK_CHANNEL_INIT): New macro. Allows a
        DISK_CHANNEL to be defined dynamically.

2005-12-02  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/disk.c: Add comments that bread/bwrite take the position and
        len in terms of blocks, not bytes.

2005-10-11  Nick Garnett  <nickg@ecoscentric.com>

        * src/disk.c (disk_bread, disk_bwrite): Made calls to
        cyg_thread_yield() dependent on presence ok kernel.

2005-06-01  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/disk.c (disk_bwrite): Uncomment the cyg_thread_yield() at
        the end to prevent thread starvation between threads at the same
        priority.
        (disk_bread): Ditto.

2004-07-21  Nick Garnett  <nickg@ecoscentric.com>

        * src/disk.c (read_partition): Changed to account for very large
        disks which report bogus CHS geometry. We can only use the LBA
        partition parameters in such disks.
        (disk_set_config): Added some extra debug output.

2004-07-01  Savin Zlobec  <savin@elatec.si> 

        * src/disk.c:
        * include/disk.h:
        * include/diskio.h:
        Use predefined arrays for partition devices and info 
        radher than malloc. Extended DISK_CHANNEL macro to
        support defining maximum number of partitions.

2004-04-15  Nick Garnett  <nickg@ecoscentric.com>

        * src/disk.c: 
        Various changes to support disconnect/reconnect of changeable
        media.

        * include/diskio.h: Added mount counter to disk_info structure.

        * include/disk.h: Changed disk_disconnected() function to take a
        pointer to a struct disk_channel rather than a struct
        cyg_devtab_entry. Added mount count to disk_channel structure.
        Moved include of diskio.h to end to fix declaration problems.

2004-02-04  Nick Garnett  <nickg@ecoscentric.com>

        * src/disk.c: Fixed bug in write routine where controller result
        field was not being initialized. Added signals on controller queue
        condition variable after setting controller busy flag to false.

        * include/disk.h: Made controller result and busy fields
        volatile. Just in case.

2004-01-23  Nick Garnett  <nickg@ecoscentric.com>

        * include/disk.h: 
        * src/disk.c:
        Many changes. Added additional disk_controller data structure to
        better reflect hardware structure. Added support for serialization
        of multithreaded accesses to a single controller. Added support
        for asynchronous, interrupt driven, IO operations. Various
        tidies.

2004-01-15  Nick Garnett  <nickg@ecoscentric.com>

        * src/disk.c:
        * include/disk.h: Removed block_pos arguments from
        hardware driver read and write calls: it is not necessary.

        * src/disk.c (read_mbr): Modified to read a complete sector from
        the disk rather than pieces. Drivers should only ever see
        reads/writes in multiples of 512 bytes.

2003-10-16 Savin Zlobec <savin@elatec.si>

        * src/disk.c:
        Check return code from MBR scan and set
        connected flag only if there was no error.

2003-09-01 Savin Zlobec <savin@elatec.si>

        * cdl/io_disk.cdl:
        * inc/disk.h:
        * inc/diskio.h:
        * src/disk.c:
        A block device IO implementation
