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. + +//=========================================================================== +//####ECOSGPLCOPYRIGHTBEGIN#### +// ------------------------------------------- +// This file is part of eCos, the Embedded Configurable Operating System. +// Copyright (C) 1998, 1999, 2000, 2001, 2002 Red Hat, Inc. +// +// eCos is free software; you can redistribute it and/or modify it under +// the terms of the GNU General Public License as published by the Free +// Software Foundation; either version 2 or (at your option) any later version. +// +// eCos is distributed in the hope that it will be useful, but WITHOUT ANY +// WARRANTY; without even the implied warranty of MERCHANTABILITY or +// FITNESS FOR A PARTICULAR PURPOSE.
