2003-10-29  Jonathan Larmour  <jifl@eCosCentric.com>

	* src/flash_unlock_block.c (flash_unlock_block): test lock bit
	explicitly - newer flash parts use the reserved bits in the
	returned data.

2003-09-11  Jani Monoses <jani@iv.ro>

	* src/flash_erase_block.c (flash_erase_block): 
	* src/flash_program_buf.c (flash_program_buf): Fix bootblock handling
	in erase. Fix erase and word-program for Synchronous Strata and later
	chips where block address and word address are required in the first
	cycle of the operation while for earlier parts any address was good.
	
2003-09-10  Jani Monoses <jani@iv.ro>
	
	* cdl/flash_strata.cdl:
	* src/flash_lock_block.c (flash_lock_block): 
	* src/flash_unlock_block.c (flash_unlock_block): 
	* src/flash_erase_block.c (flash_erase_block): 
	* src/flash_query.c (flash_query): 
	* src/flash_program_buf.c (flash_program_buf): Use .2ram sections 
	for putting flash functions to RAM instead of the old method.
	
2003-05-02  Jani Monoses <jani@iv.ro>

	* src/strata.c: Switch to using generic flash_query_dev.
	The previous cache related changes broke flash_query for
	Strata because in the query case the generic flash driver was not
	called to handle the caches but the internal handling was removed
	nevertheless.
	
2003-04-04  Jani Monoses <jani@iv.ro>
	
	* src/strata.h:
	Use generic flash_dev.h for providing the FLASHWORD macro for
	different widths and device numbers.No reason to duplicate that
	here.This implicitely fixes the case when CYGNUM_FLASH_WIDTH is 16
	and CYGNUM_FLASH_DEVICES is 4.

2003-04-03  Jani Monoses <jani@iv.ro>

	* src/flash_lock_block.c (flash_lock_block): 
	* src/flash_unlock_block.c (flash_unlock_block): 
	* src/flash_erase_block.c (flash_erase_block): 
	* src/flash_query.c (flash_query): 
	* src/flash_program_buf.c (flash_program_buf): 
	Cache enabling and disabling are already handled by generic flash
	
2002-08-12  Mark Salter  <msalter@redhat.com>

	* src/flash_unlock_block.c: Add synchronous strataflash support.
	* src/strata.h: Add comments regarding synchronous strataflash.

2002-04-30  Christoph Csebits  <christoph.csebits@frequentis.com>

	* src/flash_unlock_block.c: Getting the current block lock
	state for flashes in 8-Bit mode is now working correctly.

2002-04-16  Jonathan Larmour  <jlarmour@redhat.com>

	* cdl/flash_strata.cdl: Invoke $(CC) with $(CFLAGS) to ensure the
        correct flags are passed.

2002-04-12  Gary Thomas  <gthomas@redhat.com>

	* src/strata.c: Clean up warnings.

2002-01-22  Mark Salter  <msalter@redhat.com>

	* cdl/flash_strata.cdl: Add ".text" before "_end" markers in .s files.

2001-10-23  Hugo Tyson  <hmt@redhat.com>

	* cdl/flash_strata.cdl: Provide an option so that RedBoot .ecm
	files can turn off the functionality of copying flash driver code
	to separate RAM for execution; it's not needed for RAM and ROMRAM
	startup, and for some platforms it is required to *not* copy thus.

2001-08-25  Gary Thomas  <gthomas@redhat.com>

	* src/flash_program_buf.c (flash_program_buf): Allow configuration
	specific code sequence for actual writing of data.  Define by the
	macro CYGHWR_FLASH_WRITE_ELEM.  Note: this is required on some
	hardware, like the Intel SA185, which handles flash writes in
	strange/obscure fashion.

2001-07-17 Jeroen Dobbelaere  <jeroen.dobbelaere@acunia.com>

	* src/flash_query.c (flash_query): Query needs to be done on even
	addresses for byte-enabled strata flash 

	* src/flash_program_buf.c (flash_program_buf): Fix of conversion of
	write buffer length (in bytes) to the length in 'flash_t' words.

2001-06-22  Hugo Tyson  <hmt@redhat.com>

	* src/strata.c (flash_hwr_init): Need to refer to the query code
	as extern char flash_query[], flash_query_end[]; (with the []) or
	MIPS code gen assumes these are short offsets and linking fails.
	The generic flash code in io/flash already uses this idiom.

2001-06-22  Hugo Tyson  <hmt@redhat.com>

	* src/strata.c (flash_hwr_init): Warnings reduced.  No arithmetic
	on void *.

2001-06-21  Hugo Tyson  <hmt@redhat.com>

	* src/flash_program_buf.c (flash_program_buf): The buffered write
	code didn't jump out if there was a write error, nor verify the
	data by reading back.  This isn't consistent with the slow case,
	and made it take an age if the device is unhappy, and then report
	a bizarre error code.  Both issues fixed.

2001-06-21  Hugo Tyson  <hmt@redhat.com>

	* src/strata.c (flash_hwr_init): If shrinking to fit, must also
	adjust the flash_info.blocks field, else unlock crashes trying to
	get status of all those extra blocks that we cannot actually see.

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

	* src/strata.c: Remove dependency on printf() via user functions.

2001-06-07  Hugo Tyson  <hmt@redhat.com>

	* src/strata.c (flash_hwr_init): If we find a flash device that is
	larger than is possible given the memory map, shrink to fit.
	We know about the memory map from CYGNUM_FLASH_BASE_MASK (if
	defined); it tells us the stride from one device to another.

	This is to cope with installing, say, a 28F640 in a slot designed
	for a 28F320 because of supply issues - it all works fine so long
	as A22 is grounded.

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

	* cdl/flash_strata.cdl: Needs IO driver to copy functions to RAM.

2001-04-26  Gary Thomas  <gthomas@redhat.com>

	* src/strata.c: Be more careful when enable/flush/disable caches.

	* src/flash_erase_block.c (flash_erase_block): Boot block devices
	may require additional erase commands to erase entire 'block'.

2001-03-21  Hugo Tyson  <hmt@redhat.com>

	* src/strata.h (FLASH_Write_Buffer): Do not define this if
	CYGOPT_FLASH_IS_NOT_ADVANCED is defined; Advanced (xxxJ3) flash is
	usual these days.  Also added documentation of the options that
	can be used to control this module.
	
	* src/flash_program_buf.c (flash_program_buf): Reduce warnings
	about unused variables if no FLASH_Write_Buffer command available.

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

	* src/flash_program_buf.c (flash_program_buf): Buffered write code
	fixups, only on platforms with it defined.

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

	* src/strata.h: 
	* src/strata.c: Support buffered writes.

	* src/flash_program_buf.c: Use buffered writes if possible. This
	mode allows the chip to do parallelized writes which is much faster.
	It does require additional information, now provided by upper layer.

2001-02-15  Hugo Tyson  <hmt@redhat.com>

	* src/flash_query.c (flash_query): Depending on whether
	CYGOPT_FLASH_IS_BOOTBLOCK (just a #define from the instantiator,
	not really a cdl_option) is set, do the full Read_Query or just
	acquire two codes for manufacturer and device type using Read_ID.

	* src/strata.c (flash_hwr_init): Again depending on whether
	CYGOPT_FLASH_IS_BOOTBLOCK, decode the device type into a size and
	so on, or use the full Read_Query data as before.

	* src/strata.h (FLASH_Read_ID): Undefine those commands which we
	do not use.  Conditionally define those that we use depending on
	CYGOPT_FLASH_IS_BOOTBLOCK.  Thus we should be able to deal with
	StrataFlash and BootBlock flash with the same code.

	* cdl/flash_strata.cdl: Do not implement (in the CDL sense)
	CYGHWR_IO_FLASH_BLOCK_LOCKING leave it up to the instantiating
	package instead.  Also move the build of the two objects that do
	locking and unlocking into a compenent which is only active if
	CYGHWR_IO_FLASH_BLOCK_LOCKING is indeed (requested to be)
	implemented somewhere.

2001-02-14  Hugo Tyson  <hmt@redhat.com>

	* devs/flash/intel/strata/...: New package, generic strataFlash
	driver based on several others; a portion of its history
	follows...

	flash.h -> strata.h
	flash<platform>.c -> strata.c

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

	* src/flash.h: Much more generic again.  Not yet separated into
	generic component and invocation header, but the structure is
	there.  Also included support for a mapping from the physical
	flash address we're thinking of to the virtual address we use to
	access it.  More documentation.  Generalization to 8,16,32 and
	64-bit access, made up from 8,16 or 32-bit devices.  Command and
	status macros modified to accommodate these options.

	* src/flash_lock_block.c (flash_lock_block): 
	* src/flash_erase_block.c (flash_erase_block): 
	* src/flash_query.c (flash_query): 
	* src/flash_program_buf.c (flash_program_buf): 
	All now acquire when possible the ROM address from the block
	address, and use the physical to virtual macro as needed.

	* src/flash_unlock_block.c (flash_unlock_block): 
	The same changes, but a little more complex because of the need to
	clear-all then re-lock some semantics.  Shadow pointer to virtual
	address is used each time round the loop.

	* cdl/flash_strata.cdl: Add explicit dependencies on flash.h, for
	there were none - or they were ignored - for the specially built
	compilation units that get copied to RAM for execution.

2001-02-01  Hugo Tyson  <hmt@redhat.com>

	* all: copied from the assabet flash driver.

2000-12-05  Jonathan Larmour  <jlarmour@redhat.com>

	* src/assabet_flash.c (flash_code_overlaps): Define stext/etext
	as array types so no assumptions can be made by the compiler about
	location.

2000-10-24  Gary Thomas  <gthomas@redhat.com>

	* src/flash_unlock_block.c (flash_unlock_block): 
	* src/flash_lock_block.c (flash_lock_block): 
	* src/flash_program_buf.c (flash_program_buf): 
	* src/flash_erase_block.c (flash_erase_block): Support up to 32M FLASH.

2000-09-10  Gary Thomas  <gthomas@redhat.com>

	* src/flash_unlock_block.c: 
	* src/flash_lock_block.c: New file(s).

	* src/flash.h: 
	* cdl/flash_assabet.cdl: Add region locking functions.

2000-08-29  Gary Thomas  <gthomas@redhat.com>

	* src/assabet_flash.c: Improve error decoding.

2000-08-24  Gary Thomas  <gthomas@redhat.com>

	* src/flash_query.c: 
	* src/flash_erase_block.c: 
	* src/flash.h: FLASH support for Intel SA1110 Assabet.
