2009-04-20  Rene Schipp von Branitz Nielsen 

        * src/am29xxxxx.c: Added set of parentheses around macro

        parameters used in multiplications. Fixes 16as8 bug.

2008-12-19  Jonathan Larmour  

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

2008-11-20  Jonathan Larmour  

        * cdl/flash_am29xxxxx_v2.cdl: Fix doc link.

2008-09-24  Bart Veer  

        * src/am29xxxxx_aux.c (am29_hw_program): fix handling of parallel

        chips. Get the debug diagnostics to build cleanly.

2008-05-13  Jonathan Larmour  

        * src/am29xxxxx_aux.c (am29_hw_query): Allow devices to return

        device IDs of larger than a byte.

2007-07-08  Bart Veer  

        * 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  

        * 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  

        * src/am29xxxxx.c: skip data cache manipulation on architectures

        which do not have a data cache.

2007-05-29  Jonathan Larmour  

        * 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  

        * 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  

        * src/am29xxxxx_aux.c (am29_hw_cfi): Added missing AM29_SWAP() to

        fetch of offset of vendor specific data.

2006-09-27  Nick Garnett  

        * 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  

        * 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  

        * 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  

        * 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  

        * doc/am29xxxxx.sgml: Fix missing  tag.

        * cdl/flash_am29xxxx_v2.cdl: Reference package documentation.

2005-09-26  Bart Veer  

        * 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  

        * 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  

        * 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  

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

2005-01-19  Jonathan Larmour  

        * 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  

        * src/am29xxxxx.c, include/am29xxxxx_dev.h: 

        no longer exists, use  instead.

2004-11-29  Bart Veer  

        * 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  

        * 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  

        * 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  

        * 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  

        * New AM29xxxxx flash driver created
