(disk_init): No longer set entry 0 from device devtab. It's unnecessary. * 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. * 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. * include/disk.h (DISK_CHANNEL_INIT): New macro. Allows a DISK_CHANNEL to be defined dynamically. * src/disk.c (disk_bread, disk_bwrite): Made calls to cyg_thread_yield() dependent on presence ok kernel. * 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. * 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. * 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. * 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. * 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.
