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
