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.

2008-11-23  Sergei Gavrikov  <sergei.gavrikov@gmail.com>

	* doc/flash.sgml: Fix flash.h header name typos.

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/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

	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>

	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/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.

2004-04-29  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>

	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.

	devices.  This includes a generic "flash_read_buf()" function.

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

	* include/flash_dev.h: Include <cyg/infra/cyg_type.h> 

2003-03-19  Thomas Koeller <thomas.koeller@baslerweb.com>

	* src/flashiodev.c: Fixed trivial error.

2003-03-03  Knud Woehler <knud.woehler@microplex.de>

	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

	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.

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.

	* 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.
