Spotted by Jose Pascual 2001-10-16 Jesper Skov * src/flash.c: Include string.h * cdl/io_flash.cdl: Package requires ISOINFRA and string functions. 2001-10-15 David Howells * src/flash.c: Include string.h to get mem*() functions. 2001-09-25 Gary Thomas * include/flash.h: Remove warning on printf() prototype. 2001-08-10 Jesper Skov * cdl/io_flash.cdl: Changed flavor of CYGHWR_IO_FLASH_BLOCK_LOCKING to booldata. * include/flash.h: Matching changes. * src/flash.c: Matching changes. 2001-07-23 David Howells * cdl/io_flash.cdl: Added software write protect option. * include/flash.h: Ditto. * src/flash.c: Added software write protect option and bank support, and prevented low-level writes from being handed cross-block data chunks. 2001-07-20 Gary Thomas * include/flash.h: * cdl/io_flash.cdl: Name convention: CYGINT_FLASH_WORKSPACE_SIZE renamed to be CYGNUM_FLASH_WORKSPACE_SIZE. 2001-07-19 Gary Thomas * include/flash.h: * cdl/io_flash.cdl: New option CYGINT_FLASH_WORKSPACE_SIZE used to control how much memory is reserved for use by FLASH drivers. 2001-06-19 Hugo Tyson * 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. (flash_init): Fix bug in removal of dependency of printf(). The pointer was not initialized until after the call into the driver. 2001-06-11 Gary Thomas * src/flash.c: * include/flash.h: Remove dependency on printf() via user functions. 2001-05-23 Jesper Skov * include/flash_dev.h (FLASH_P2V): Use CYG_ADDRWORD instead of int. * src/flash.c: Copy functions to RAM iff CYGHWR_IO_FLASH_DEVICE_NOT_IN_RAM defined. * cdl/io_flash.cdl: Changed CYGHWR_IO_FLASH_DEVICE_IN_RAM to CYGHWR_IO_FLASH_DEVICE_NOT_IN_RAM. 2001-05-21 Jonathan Larmour * include/flash_dev.h: Fix cyg_uin16 typo. 2001-03-29 Mark Salter * cdl/io_flash.cdl (CYGSEM_IO_FLASH_VERIFY_PROGRAM): New option to control whether or not to perform extra verification of flash programming. * src/flash.c (flash_program): No verification unless CYGSEM_IO_FLASH_VERIFY_PROGRAM defined. 2001-03-21 Gary Thomas * src/flash.c (flash_program): Verify data after programming. 2001-03-21 Jesper Skov * include/flash.h: Added low voltage error message. * src/flash.c: And its error message. 2001-03-17 Gary Thomas * 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 * 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 * 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 * 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 * 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 * 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 * src/flash.c: Do all flash access inside properly cache-controlled region. * include/flash.h: Cache definitions. 2000-11-17 Jesper Skov * src/flash.c: Added debug mode, allowing device driver to use printf. 2000-11-16 Jesper Skov * src/flash.c: Added suspend error messages. * include/flash.h: Same. 2000-09-01 Hugo Tyson * 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 * src/flash.c: * include/flash.h: * cdl/io_flash.cdl: Support block locking (optional by hardware). 2000-08-22 Hugo Tyson * 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 * include/flash.h: Add block size mask for finding block boundaries. * src/flash.c: Use block size properly. 2000-07-29 Gary Thomas * include/flash.h: * src/flash.c (flash_get_block_info): New function. (flash_program): Program in block_size chunks as much as possible. //=========================================================================== //####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.
