        * cdl/io_flash.cdl: Fix "requires" constraint on
        CYGNUM_IO_FLASH_BLOCK_OFFSET_n to allow positioning of block
        device at offset 0 in flash when using static configuration via
        offset.  Fix display string for CYGSEM_IO_FLASH_LEGACY_API option.

2009-03-02  Sergei Gavrikov  <sergei.gavrikov@gmail.com>

        * doc/flash.sgml: Fixed typos in a FLASH API listing.

2009-02-20  Jonathan Larmour  <jifl@eCosCentric.com>

        * include/flash.h: Reinstate printf arg to cyg_flash_init, but it
        will now be officially required to be set to NULL.
        * src/flash.c (cyg_flash_init): Act on printf arg again (even though
        it's not meant to be non-NULL).
        * src/flashiodev.c (flashiodev_init): Call cyg_flash_init with NULL.
        * src/flashiodevlegacy.c (flashiodev_init): Ditto.
        * src/legacy_api.c (flash_init): Ditto.
        * doc/flash.sgml: Update cyg_flash_init as above, deprecating use of
        non-NULL parameter.

2009-02-18  Jonathan Larmour  <jifl@eCosCentric.com>

        * include/flash.h: Modest API change: cyg_flash_init() no longer
        takes a printf function argument. Instead two new API functions
        are available: cyg_flash_set_printf() and
        cyg_flash_set_global_printf().
        
        * src/flash.c (CHATTER): Don't attempt output if printf function
        is NULL.
        (cyg_flash_init): No longer takes printf arg.
        (cyg_flash_set_printf): New. Set per-device printf function, locking
        if needed.
        (cyg_flash_set_global_printf): New. Set printf function for all
        devices, locking if needed.
        
        * src/flashiodev.c (flashiodev_init): cyg_flash_init no longer takes
        printf arg, and we can leave global printf at default.
        * src/flashiodevlegacy.c (flashiodev_init): Ditto.

        * src/legacy_api.c (flash_init): cyg_flash_init no longer takes
        printf arg. So call cyg_flash_set_global_printf as well.

        * src/legacy_dev.c (legacy_flash_init): legacy drivers can't handle
        NULL printf function, so provide a dummy.

        * doc/flash.sgml: Document removal of printf functionality of
        cyg_flash_init() and document cyg_flash_set_printf() and
        cyg_flash_set_global_printf().

2009-02-13  Bart Veer  <bartv@ecoscentric.com>

        * doc/flash.sgml: remove incomplete sentence.

        * cdl/io_flash.cdl: remove CYGHWR_IO_FLASH_DEVICE_NOT_IN_RAM, no
        longer needed.

2008-11-18  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flash.c (cyg_flash_init): Allow repeated calls to
        change the printf function for all devices. There are
        times you don't any output, eg you are downloading an
        image over the serial port.

2008-08-29  Nick Garnett  <nickg@ecoscentric.com>

        * src/flashiodev.c (flashiodev_init): Assign
        CYG_DEVTAB_STATUS_BLOCK to status field of device table
        entries. This causes devfs to call the right read/write
        operations.

2008-06-10  Jonathan Larmour  <jifl@eCosCentric.com>

        * tests/flashdev.c (FLASH_TEST_LENGTH): Reduce to a
        multiple of 0x20000 as some flash parts (especially if
        they are in fact multiple chips in parallel) have that
        block size.
        Try opening jffs2test FIS partition if flashtest doesn't exist.

2007-05-14  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flashiodev.c (flashiodev_get_config): Support new
        CYG_IO_GET_CONFIG_FLASH_DEVADDR key to get flash device
        base address.
        * include/flash.h: Associated structure for key.
        * doc/flash.sgml: Document CYG_IO_GET_CONFIG_FLASH_DEVADDR.

2006-12-18  Jonathan Larmour  <jifl@eCosCentric.com>

        * tests/flash1.c: Replace FLASH_ERR_OK with CYG_FLASH_ERR_OK.
        * tests/flashdev.c: Ditto. Also flash_errmsg ->
        cyg_flash_errmsg. And some warning cleanups.

        * src/flashiodev.c (flashiodev_lookup): Correct misplaced else
        with respect to #ifdefs. Fix for bug 1000355.

2006-12-18  Nick Garnett  <nickg@ecoscentric.com>

        * src/flash_legacy.h (FLASH_Enable, FLASH_Disable): Add casts to
        these macros since the calls in the source don't present the right
        types. This is mainly an exercise in suppressing compiler
        warnings.

2006-12-07  Nick Garnett  <nickg@ecoscentric.com>

        * tests/flashdev.c (cyg_start): Fix bug, b.offset should be
        initialized to 0. Until now it was some random value on the stack,
        why this has never bitten us before is a mystery.

2006-10-31  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/legacy_dev.c (legacy_flash_program): Define block_size.

2006-10-03  Jonathan Larmour  <jifl@eCosCentric.com>

        * doc/flash.sgml: Bring into line with actual implementation.
        Also some trivial typos.

2006-08-01  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flash.c (cyg_flash_devfn_lock_nop): Don't return error
        if this is used with one of multiple flash devices in a
        system where a different one does support locking.
        (cyg_flash_devfn_unlock_nop): Ditto.

2006-06-06  John Dallaway  <jld@ecoscentric.com>

        * cdl/io_flash.cdl: Fix reference to package documentation.

2006-05-23  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flash.c (cyg_flash_erase): Report errors and error
        addresses correctly.
        (cyg_flash_program): Ditto.

2005-12-21  Jonathan Larmour  <jifl@eCosCentric.com>

        * doc/flash.sgml: Document flash block device lock/unlock config keys.

2005-10-26  Nick Garnett  <nickg@ecoscentric.com>

        * include/flash.h (cyg_io_flash_getconfig_lock_t) 
        (cyg_io_flash_getconfig_unlock_t): Added these aliases for
        cyg_io_flash_getconfig_erase_t. 

        * cdl/io_flash.cdl: Added configury to control compilation of
        flash1 test. Added flashdev test.

        * src/legacy_api.c (flash_lock, flash_unlock): Added these functions.

        * src/flashiodev.c (flashiodev_get_config): Added support for lock
        and unlock operations.

        * tests/flashdev.c: Added this test to exercise flash /dev/flash
        device. Functionally it is similar to the flash1 test.

        * tests/flash1.c : Changed test for legacy API.
        (cyg_start): Added tests for lock and unlock functions.

2005-09-28  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flash.c (flash_sort_and_check): Allow for Flash
        device initialisation to fail, and thus not put this device
        on the Flash device list.

2005-09-26  Bart Veer  <bartv@ecoscentric.com>

        * src/flash.c: put init flag into .bss rather than .data, avoids
        some problems when performing soft resets.

2005-08-16  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flash.c (cyg_flash_read): Comment out chatter. It's not
        very useful for this function.

2005-08-02  Andrew Lunn  <andrew.lunn@ascom.ch>

        * tests/flash1.c (cyg_start): Compiler warning fixes.

2005-05-27  Jonathan Larmour  <jifl@eCosCentric.com>

        * tests/flash1.c (cyg_start): Call CYG_TEST_INIT().

2005-03-27  Andrew Lunn  <andrew.lunn@ascom.ch>

        * tests/flash1.c: Fixed compiler warning with diag_printf.

2005-02-28  Jonathan Larmour  <jifl@eCosCentric.com>

        * include/flash.h: Getconfig/setconfig definitions are relevant for
        both new and legacy block device support.

2005-01-28  Nick Garnett  <nickg@ecoscentric.com>

        * src/legacy_dev.c (legacy_flash_init): Assign flash_info.pf from
        flash device field. Otherwise drivers try to call an invalid
        address.
        (legacy_flash_program): The last argument to flash_program_buf()
        is not the block size but the programming buffer size.

2005-01-21  Jonathan Larmour  <jifl@eCosCentric.com>

        * doc/flash.sgml: Document Flash block devices.

2005-01-19  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flashiodev.c: Redesign to use more flexible flash names.
        * src/flashiodevlegacy.c: Previous version of flashiodev.c renamed
        to this.
        * cdl/io_flash.cdl: Support new flashiodev design.
        * include/flash.h: don't double indirect err_address address
        pointer in cyg_io_flash_getconfig_erase_t.
        * src/flash_legacy.h: Undef HAL_FLASH_CACHES_* macros if the HAL
        supplied them and they're not needed.

        * src/legacy_api.c (flash_errmsg): Was missing. Add.

        * tests/flash1.c (cyg_start): Silence warning.

2004-12-02  Bart Veer  <bartv@ecoscentric.com>

        * include/flash_dev.h: now provides everything needed by flash
        device drivers.

        * include/flash_priv.h: removed, subsumed by flash_dev.h
        
        * include/flash.h, src/flash.c, src/flashiodev.c,
          src/legacy_api.c, src/legacy_dev.c:
        Replace implicit #include's of <cyg/io/flash_priv.h> with explicit
        #include's of <cyg/io/flash_dev.h>

2004-11-29  Bart Veer  <bartv@ecoscentric.com>
        
        * include/flash_priv.h, src/flash.c, src/legacy_dev.c: remove
        hwr_map_error() from V2 drivers

        * include/flash_priv.h, src/flash.c, src/legacy_dev.c: provide
        dummy init/query/lock/unlock functions for use by device drivers
        which do not support/need this functionality. Export the
        anonymizer function.

2004-11-28  John Dallaway  <jld@ecoscentric.com>

        * doc/flash.sgml: Fix minor SGML tag problems.

2004-11-28  Bart Veer  <bartv@ecoscentric.com>

        * src/flash.c (flash_sort_and_check): previous patch would have
        resulted in init failure if only one device initialized.
        (cyg_flash_get_info): handle per-device init flag

2004-11-25  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flash.c (flash_sort_and_check): Don't add devices which
        failed to initialise onto the list. Don't bother sorting the
        list if its empty or only has one entry.
        * src/flash.c (find_dev): All devices on the list are initialised so
        don't both checking the init flag.

2004-11-24  Bart Veer  <bartv@ecoscentric.com>

        * cdl/io_flash.cdl, src/flash.c, src/flash_legacy.h,
        src/legacy_dev.c: add support for V2 drivers which can take care
        of the cache and interrupts themselves.

        * tests/flash1.c (cyg_start): mark N/A for now if a V2 driver is
        being used.
        * Merge from flash V2 branch
        
  2004-11-22  Bart Veer  <bartv@ecoscentric.com>

        * src/legacy_dev.c: remove .2ram attributes. These functions do
        not manipulate the hardware, there is no need for them to live in
        ram rather than flash
        * include/flash_priv.h, src/legacy_dev.c: clean up the interface
        between the generic flash code and the device drivers
        * include/flash_priv, src/flash_legacy.h, src/flash.c,
        src/legacy_dev.c: move cache stuff andother legacy macros
        to an internal header.
        * include/flash.h, include/flash_priv.h, doc/flash.sgml,
        src/flash.c, src/legacy_dev.c: put const in the right places,
        and rename cyg_block_info to cyg_flash_block_info

  2004-11-21  Bart Veer  <bartv@ecoscentric.com>

        * src/flash.c, include/flash_priv.h, cdl/io_flash.h: optimize
        for the case of a single flash device.
        * include/flash.h, src/flash.c, doc/flash.sgml: remove
        cyg_flash_code_overlaps()
        * include/flash_priv.h, include/flash.h:
        CYGSEM_IO_FLASH_LEGACY_DEVICE_API has been removed, test
        CYGHWR_IO_FLASH_DEVICE_LEGACY instead 
        * cdl/io_flash.cdl: lots of clean-ups
        * src/legacy_dev.c (legacy_flash_read): only needed if the
        underlying legacy driver required indirect reads.
        * src/flash.c: encapsulate various optional bits of code in
        macros, to cut down on the #ifdef's in the main code

  2004-11-20  Bart Veer  <bartv@ecoscentric.com>

        * cdl/io_flash.cdl, src/flash.c(cyg_flash_read): add an interface
        for hardware which requires indirect reads, and suppress
        unnecessary code if direct reads are always available.
        * src/flash.c: rearrange loops to avoid address comparisons, which
        tend to go wrong if the flash is at the end of the address space

  2004-10-06  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/legacy_dev.c (legacy_flash_init): The end is the size plus
        the start.

  2004-09-30  Savin Zlobec <savin@elatec.si>

        * src/flash.c: Offset into the block is not calculated correctly
        when the flash start is not aligned on a flash block.
        * src/legacy_dev.c (legacy_flash_read): Fixed typo.

  2004-09-14  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flash.c (cyg_flash_init): Add assert checking that the
        end address matches the block information.
        * src/legacy_dev.c (legacy_flash_init): Ensure that the end
        address is the last valid address, not the first invalid address.

  2004-09-09  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flash.c: Support flash blocks of arbitary size. The
        DataFlash devices for example have block of 528 bytes.

  2004-08-21  Andrew Lunn  <andrew.lunn@ascom.ch>

        * removed the functions cyg_flash_get_limits and
        cyg_flash_get_block_info. Reimplemented the legacy functions
        that depended on them and flashiodev.c
        
  2004-08-19  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flashiodev.c Ordering problem again. If an invalid name is
        configured the lookup would fail and it then was impossible to do
        a cyg_io_config_set. Lookup cannot fail because the name does not
        exist in FIS.

  2004-08-13  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flash.c: Make the flock lock/unlock code compile without
        warnings.
        * src/flashiodev.c (flashiodev_lookup): Only initialize the device
        if we have not already been initialized via cyg_set_config().
        This stopped redboots mount -f working.

  2004-08-09  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flashiodev.c (flashiodev_lookup): Moved most of the
        flashiodev_init into this new function. This fixed the ordering
        issue with redboot startup. When doing a FIS name lookup in
        flashiodev_init, redboot was not yet nitialised so lookup
        failed. Moving this into flashiodev_lookup solves this problem.
        Its now possible for redboot to mount the jffs2 filesystem with 
        -d /dev/flash1.

  2004-08-06  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flashiodev.c: Fix typo in macro and configuration options
        
  2004-08-05  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flash.c: Major rewrite to implement a new API
        * src/legacy_api.c: Support the legacy API
        * src/legacy_drv.c: Support the legacy driver API
        * src/flashiodev.c: Support the new API and multiple devices
        * include/flash_priv.h: Interface devices should use
        * cdl/io_flash.cdl: Updates for new interface and multiple devices.
        
2004-09-05  Mark Salter  <msalter@redhat.com>

        * doc/flash.sgml: Fix unbalanced <PARA>s.

2004-08-24  Gary Thomas  <gary@mlbassoc.com>

        * cdl/io_flash.cdl:
        * tests/flash1.c: Add simple test of FLASH driver.

2004-06-20  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flash.c (flash_read): Don't check if the flash is write 
          protected before performing a read.
        * doc/flash.sgml
        * cdl/io_flash.cdl: Added documentation of the FLASH API

2004-04-29  Sebastien Couret  <sebastien.couret@elios-informatique.com>
2004-04-29  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/flashiodev.c: When checking flash upper bound, allow for end
        of flash at 0xffffffff.

2003-11-27  David Woodhouse  <dwmw2@infradead.org>

        * src/flashiodev.c: Enable set_config() and implement
        CYG_IO_SET_CONFIG_FLASH_FIS_NAME.
        
2003-11-25  Andrew Lunn  <andrew.lunn@ascom.ch>

        * src/flash.c: gcc 3.x vs gcc 2.x problems. 

2003-11-24  Jani Monoses  <jani@iv.ro>

        * cdl/io_flash.cdl:
        * include/flash.h: Remove CYGNUM_FLASH_WORKSPACE_SIZE cdl option. 
 
2003-11-24  Roland Caßebohm <roland.cassebohm@visionsystems.de>

        * src/flashiodev.c (flashiodev_bwrite): Use flash_read rather than
        directly doing a memcpy. 

2003-11-20  Jani Monoses  <jani@iv.ro>

        * src/flash.c: 
        * src/flashiodev.c: 
        * include/flash.h: Remove references to work_space and work_space_size
        since they are no longer used.

2003-11-20  Jani Monoses  <jani@iv.ro>

        * cdl/io_flash.cdl:
        * src/flash.c: Remove handling of CYGHWR_IO_FLASH_DEVICE_NOT_IN_RAM
        now that all flash drivers use ELF sections to specify which parts
        go in RAM.

2003-10-08  Roland Cassebohm  <roland.cassebohm@visionsystems.de>

        * src/flash.c: Fix parse error if CYGSEM_IO_FLASH_READ_INDIRECT 
        is not defined.

2003-09-19  Gary Thomas  <gary@mlbassoc.com>

        * src/flash.c: 
        * include/flash.h: 
        * cdl/io_flash.cdl: Add support for NAND (indirectly accessed)
        devices.  This includes a generic "flash_read_buf()" function.

2003-04-14  Jani Monoses  <jani@iv.ro>

        CYGNUM_IO_FLASH_BLOCK_CFG_STATIC_1. Initialize the block device 
        from the FIS table.
        
2003-02-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/io_flash.cdl: Remove irrelevant doc link - default to top
        level.

2002-01-31  Jonathan Larmour  <jlarmour@redhat.com>

        * src/flashiodev.c: Fix bounds checking and offsetting.

        * cdl/io_flash.cdl (CYGNUM_IO_FLASH_BLOCK_LENGTH_1): Default to
        0x100000 for convenience.

2002-01-30  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/io_flash.cdl: Allow specification of an offset and length
        of the region of flash.
        * src/flashiodev.c: Use it.

2002-01-24  Jesper Skov  <jskov@redhat.com>

        * include/flash.h: Add a comment about the obvious: the flash
        caching macros should be called with interrupts disabled.

2002-01-23  Jonathan Larmour  <jlarmour@redhat.com>

        * cdl/io_flash.cdl: Add CYGPKG_IO_FLASH_BLOCK_DEVICE and
        CYGDAT_IO_FLASH_BLOCK_DEVICE_NAME_1 to allow exporting flash
        as block devices accessible from file systems.
        * src/fileiodev.c: New file implementing this.
        * include/flash.h: Add typedefs for the various structures used
        to configure the block devices.

2002-01-18  Paul Fine  <pfine@delcomsys.com>

        * src/flash.c : Modified flash_verify_addr, flash_erase,
        flash_lock and flash_unlock to to work properly when the location
        of the flash in the memory map is at the very top of the address
        space.  We check and handle values that may overflow.

2001-10-28  Gary Thomas  <gthomas@redhat.com>

        * src/flash.c (flash_erase): Don't call hardware layer if block
        appears to be already erased [faster and less wear & tear].

2001-10-25  Jonathan Larmour  <jlarmour@redhat.com>

        * include/flash_dev.h: Fix test of 4x16-bit flash parts.
        Spotted by Jose Pascual <josepascual@almudi.com>

2001-10-16  Jesper Skov  <jskov@redhat.com>

        * src/flash.c: Include string.h

        * cdl/io_flash.cdl: Package requires ISOINFRA and string
        functions.

2001-10-15  David Howells  <dhowells@redhat.com>

        * src/flash.c: Include string.h to get mem*() functions.

2001-09-25  Gary Thomas  <gthomas@redhat.com>

        * include/flash.h: Remove warning on printf() prototype.

2001-08-10  Jesper Skov  <jskov@redhat.com>

        * cdl/io_flash.cdl: Changed flavor of
        CYGHWR_IO_FLASH_BLOCK_LOCKING to booldata.
        * include/flash.h: Matching changes.
        * src/flash.c: Matching changes.

2001-07-23  David Howells  <dhowells@redhat.com>

        * cdl/io_flash.cdl: Added software write protect option.
        * include/flash.h: Ditto.
        * src/flash.c: Added software write protect option and bank
        support, and prevented low-level writes from being handed
        cross-block data chunks.

2001-07-20  Gary Thomas  <gthomas@redhat.com>

        * include/flash.h: 
        * cdl/io_flash.cdl: Name convention: CYGINT_FLASH_WORKSPACE_SIZE 
        renamed to be CYGNUM_FLASH_WORKSPACE_SIZE.

2001-07-19  Gary Thomas  <gthomas@redhat.com>

        * include/flash.h: 
        * cdl/io_flash.cdl: New option CYGINT_FLASH_WORKSPACE_SIZE used
        to control how much memory is reserved for use by FLASH drivers.

2001-06-19  Hugo Tyson  <hmt@redhat.com>

        * src/flash.c (flash_program): Only verify program with memcmp if
        the status code suggests the programming went OK so far.
        Otherwise all errors become verify errors.

        (flash_init): Fix bug in removal of dependency of printf().  The
        pointer was not initialized until after the call into the driver.

2001-06-11  Gary Thomas  <gthomas@redhat.com>

        * src/flash.c: 
        * include/flash.h: Remove dependency on printf() via user functions.

2001-05-23  Jesper Skov  <jskov@redhat.com>

        * include/flash_dev.h (FLASH_P2V): Use CYG_ADDRWORD instead of int.

        * src/flash.c: Copy functions to RAM iff
        CYGHWR_IO_FLASH_DEVICE_NOT_IN_RAM defined.

        * cdl/io_flash.cdl: Changed CYGHWR_IO_FLASH_DEVICE_IN_RAM to
        CYGHWR_IO_FLASH_DEVICE_NOT_IN_RAM.

2001-05-21  Jonathan Larmour  <jlarmour@redhat.com>

        * include/flash_dev.h: Fix cyg_uin16 typo.

2001-03-29  Mark Salter  <msalter@redhat.com>

        * cdl/io_flash.cdl (CYGSEM_IO_FLASH_VERIFY_PROGRAM): New option
        to control whether or not to perform extra verification of flash
        programming.
        * src/flash.c (flash_program): No verification unless
        CYGSEM_IO_FLASH_VERIFY_PROGRAM defined.

2001-03-21  Gary Thomas  <gthomas@redhat.com>

        * src/flash.c (flash_program): Verify data after programming.

2001-03-21  Jesper Skov  <jskov@redhat.com>

        * include/flash.h: Added low voltage error message.
        * src/flash.c: And its error message.

2001-03-17  Gary Thomas  <gthomas@redhat.com>

        * src/flash.c (flash_program): 
        * include/flash.h: Add support for [StrataFLASH] buffered writes.
        This requires knowledge of the device write buffer size [saved].

2001-03-01  Gary Thomas  <gthomas@redhat.com>

        * src/flash.c: 
        * include/flash.h: Allow platform to define pre/post routines
        to enable/disable device access.  These may be required, e.g.
        to turn on some voltage, etc.

2001-02-23  Jesper Skov  <jskov@redhat.com>

        * include/flash.h: HAL_FLASH_CACHES_WANT_OPTIMAL replaced with
        (opposite sense) HAL_FLASH_CACHES_OLD_MACROS.

        * src/flash.c (__anonymizer): Use to force the compiler to use
        jumps instead of branches.

2001-02-22  Jesper Skov  <jskov@redhat.com>

        * include/flash_dev.h: Added. Contains macros and definitions
        common to all (new style) flash device drivers.

        * include/flash.h: Added two new error codes.
        * cdl/io_flash.cdl: Added CYGHWR_IO_FLASH_DEVICE_IN_RAM.
        * src/flash.c: Made functions respect
        CYGHWR_IO_FLASH_DEVICE_IN_RAM and jump directly to the code
        instead of copying it around.
        (__arm_broken): Work around problem with ARM tools.

2001-02-06  Hugo Tyson  <hmt@redhat.com>

        * src/flash.c (flash_erase): Add an additional argument to the
        call into the driver, being the blocksize (as discovered).  This
        allows a gross check for actual erase in some drivers.  Those that
        don't use it, it's harmless - after all, this is an API by trust.

2000-12-06  Jesper Skov  <jskov@redhat.com>

        * src/flash.c (flash_dev_query): Added. Allows reloc/cache magic
        to be removed from device drivers (eventually). Also fixed some
        warnings, and made function references use char[] instead of just
        char to prevent MIPS compiler from messing up.

        * include/flash.h: Added FLASH_ERR_DRV_VERIFY and flash_dev_query.

2000-11-27  Jesper Skov  <jskov@redhat.com>

        * src/flash.c: Do all flash access inside properly
        cache-controlled region.
        * include/flash.h: Cache definitions.

2000-11-17  Jesper Skov  <jskov@redhat.com>

        * src/flash.c: Added debug mode, allowing device driver to use printf.

2000-11-16  Jesper Skov  <jskov@redhat.com>

        * src/flash.c: Added suspend error messages.
        * include/flash.h: Same.

2000-09-01  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/flash.h: 
        * src/flash.c: CYGHWR_IO_FLASH_BLOCK_LOCKING is an interface, so
        it's always defined; look for > 0 instead.

2000-08-28  Gary Thomas  <gthomas@redhat.com>

        * src/flash.c: 
        * include/flash.h: 
        * cdl/io_flash.cdl: Support block locking (optional by hardware).

2000-08-22  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/flash.c (flash_program): Add HAL_ICACHE_DISABLE/ENABLE pairs
        around calls to RAM copy of programming/erasing function - this is
        necessary to get reliable operation on EBSA285 and similar.
        Otherwise, what is in the instruction cache might be run instead.

2000-08-14  Gary Thomas  <gthomas@redhat.com>

        * include/flash.h: Add block size mask for finding block boundaries.

        * src/flash.c: Use block size properly.

2000-07-29  Gary Thomas  <gthomas@redhat.com>

        * include/flash.h: 
        * src/flash.c (flash_get_block_info): New function.
        (flash_program): Program in block_size chunks as much as possible.
