2009-04-20  Rene Schipp von Branitz Nielsen <rbn@vitesse.com>

        * src/am29xxxxx.c: Added set of parentheses around macro
        parameters used in multiplications. Fixes 16as8 bug.

2008-12-19  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/flash_am29xxxxx_v2.cdl: Doh, fix doc link properly.

2008-11-20  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/flash_am29xxxxx_v2.cdl: Fix doc link.

2008-09-24  Bart Veer  <bartv@ecoscentric.com>

        * src/am29xxxxx_aux.c (am29_hw_program): fix handling of parallel
        chips. Get the debug diagnostics to build cleanly.

2008-05-13  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/am29xxxxx_aux.c (am29_hw_query): Allow devices to return
        device IDs of larger than a byte.

2007-07-08  Bart Veer  <bartv@ecoscentric.com>

        * src/am29xxxxx.c, src/am29xxxxx_aux.c: add 2ram entry and exit
        hooks to give HALs some extra control over the low-level flash
        operations.

2007-06-21  Bart Veer  <bartv@ecoscentric.com>

        * src/am29xxxxx_aux.c: issue a memory barrier after every command
        that gets sent to the flash, to avoid problems with pipelines that
        mess about with write ordering.

2007-05-31  Bart Veer  <bartv@ecoscentric.com>

        * src/am29xxxxx.c: skip data cache manipulation on architectures
        which do not have a data cache.

2007-05-29  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/flash_am29xxxxx_v2.cdl
        (CYGHWR_DEVS_FLASH_AMD_AM29XXXXX_V2_RESET_NEEDS_RESUME): New option.
        Allow Flash devices to indicate that they should be sent a "resume"
        command on startup.
        * src/am29xxxxx_aux.c (am29_hw_force_all_suspended_resume): New
        function to implement above CDL.
        (cyg_am29xxxxx_init_check_dev): Call the new function.
        (cyg_am29xxxxx_init_cfi): Ditto.
        (am29_hw_cfi): manufacturer_id and vendor private areas need only
        lowest byte taken, to handle multiple parallel devices.

2007-03-29  Bart Veer  <bartv@ecoscentric.com>

        * src/am29xxxxx_aux.c (am29_hw_erase): use DQ7 to detect
        termination instead of DQ6. This avoids hardware problems where
        the toggling of DQ6 is not detected.

2007-03-05  Nick Garnett  <nickg@ecoscentric.com>

        * src/am29xxxxx_aux.c (am29_hw_cfi): Added missing AM29_SWAP() to
        fetch of offset of vendor specific data.

2006-09-27  Nick Garnett  <nickg@ecoscentric.com>

        * src/am29xxxxx_aux.c (am29_hw_cfi): Added generic code to deal
        with flash parts that may specify their erase regions in reverse
        order to reality. Removed older code that was too specific to
        particular devices.
        A few changes to the diagnostics in various places.

        * cdl/flash_am29xxxxx_v2.cdl: Replaced
        CYGHWR_DEVS_FLASH_AMD_AM29XXXXX_V2_AT49_CFI with
        CYGHWR_DEVS_FLASH_AMD_AM29XXXXX_V2_CFI_BOGOSITY. This option
        performs much the same purpose, but is generic to many more flash
        parts.

2006-08-31  Nick Garnett  <nickg@ecoscentric.com>

        * src/am29xxxxx_aux.c: Added support for ST flash parts which have
        similar, but not identical, peculiarities in their CFI data to the
        Atmel parts supported earlier.

2006-08-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * src/am29xxxxx.c: Provide a default HAL_MEMORY_BARRIER()
        define if the HAL hasn't provided one.
        * src/am29xxxxx_aux.c: Use HAL_MEMORY_BARRIER() any time the
        flash is reset back to read array mode. Some processors
        need to have their write buffers flushed.

2006-06-29  Nick Garnett  <nickg@ecoscentric.com>

        * cdl/flash_am29xxxxx_v2.cdl:
        * src/am29xxxxx_aux.c:
        Added configurable delay between each word during
        programming. Some targets seem to need this.
        Also added some simple diagnostics.

2006-05-15  John Dallaway  <jld@ecoscentric.com>

        * doc/am29xxxxx.sgml: Fix missing </refentry> tag.
        * cdl/flash_am29xxxx_v2.cdl: Reference package documentation.

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

        * src/am29xxxxx.c, src/am29xxxxx_aux.c: add AM29_SWAP() support for
        platforms where the bus connection is wired up strangely.

        * src/am29xxxxx_aux.c, cdl/flash_am29xxxxx_v2.cdl: add optional
        support for certain Atmel chips which have a peculiar
        implementation of CFI.

2005-08-17  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/flash_am29xxxx_v2.cdl: Provide new
        CYGIMP_DEVS_FLASH_AMD_AM29XXXXX_V2_LEAVE_INTERRUPTS_ENABLED
        and CYGHWR_DEVS_FLASH_AMD_AM29XXXXX_V2_CACHED_ONLY options
        to provide better control of when to enable/disable interrupts
        or caches. Taken from the Strata flash example.
        * include/am29xxxxx_dev.h: Declare cyg_at49xxxx_softlock, _hardlock
        and _unlock variants.
        * src/am29xxxxx.c: Define AT49 locking commands.
        Provide AM29_UNCACHE_ADDRESS in line with the Strata driver,
        to be controlled by the above new CDL options, in place of
        AM29_P2V.
        * src/am29xxxxx_aux.c: Provide AT49 lock status definition.
        Provide AT49 softlock/hardlock/unlock API functions and
        underlying implementation functions.
        Adopt AM29_UNCACHED_ADDRESS rename.
        * doc/am29xxxxx.sgml: Update documentation to cover AT49xxxx
        locking operations and above new CDL options.
        
2005-06-12  Bart Veer  <bartv@ecoscentric.com>

        * src/am29xxxxx_aux.c (cyg_am29xxxxx_program): remove unnecessary
        loops variable
        * cdl/flash_am29xxxxx_v2.cdl: minor reorganization to put the
        important config option first
        * doc/am29xxxxx.sgml: document the important config options

2005-02-23  Bart Veer  <bartv@ecoscentric.com>

        * doc/am29xxxxx.sgml: bring up to date.

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

        * src/am29xxxxx_aux.c (am29_hw_erase): Handle interleaved
        (parallel) flash correctly when one device finishes before another.
        (am29_hw_program): Similar.
        (cyg_am29xxxxx_program): Use assert correctly.
        
        * src/am29xxxxx.c (AM29_NEXT_DATUM_32): Use cyg_uint32, not
        cyg_uint16.
        
2004-12-02  Bart Veer  <bartv@ecoscentric.com>

        * src/am29xxxxx.c, include/am29xxxxx_dev.h: <cyg/io/flash_priv.h>
        no longer exists, use <cyg/io/flash_dev.h> instead.

2004-11-29  Bart Veer  <bartv@ecoscentric.com>

        * include/am29xxxxx_dev.h, src/am29xxxxx.c: eliminate
        hwr_map_error() support, no longer needed
        
        * include/am29xxxxx_dev.h, src/am29xxxxx.c, src/am29xxxxx_aux.c:
        The dummy init/query/lock/unlock functions have been moved to the
        generic flash package. That also now exports an anonymizer
        function.

2004-11-25  Bart Veer  <bartv@ecoscentric.com>

        * cdl/flash_am29xxxxx_v2.cdl, src/am29xxxxx.c,
        src/am29xxxxx_aux.c: this driver can manage the flash and
        interrupts itself, without support from the generic flash code.

2004-11-22  Bart Veer  <bartv@ecoscentric.com>

        * include/am29xxxxx_dev.h, src/am29xxxxx.c, src/am29xxxxx_aux.c,
        doc/am29xxxxx.sgml: implement changes to the interface between the
        generic flash code and the device drivers.
        * include/am29xxxxx_dev.h: rename cyg_block_info to
        cyg_flash_block_info

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

        * doc/am29xxxxx.sgml: describe CDL implications for custom locking
        functions and additional devices.
        
        * cdl/flash_am29xxxxx_v2.cdl: CYGHWR_IO_FLASH_DEVICE_V2 is now
        implicit

2004-11-05  Bart Veer  <bartv@ecoscentric.com>

        * New AM29xxxxx flash driver created
