+
+ * 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:
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
