From 79b4cda076069d04122f0d863bcb822b5e596c93 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 28 Feb 2006 15:29:58 +0100 Subject: Major CFI-FLASH driver update: * Add env-variable "unlock" to handle initial state of sectors (locked/unlocked). Only the U-Boot image and it's environment is protected, all other sectors are unprotected (unlocked) if flash hardware protection is used (CFG_FLASH_PROTECTION) and the environment variable "unlock" is set to "yes". Patch by Stefan Roese, 28 Feb 2006 * Update drivers/cfi_flash.c: - find_sector() called in both versions of flash_write_cfiword() Patch by Peter Pearse, 27th Feb 2006 * CFI support for a x8/x16 AMD/Spansion flash configured in x8 mode Patch by Jose Maria Lopez, 16 Jan 2006 * Add support for AMD/Spansion Flashes in flash_write_cfibuffer Patch by Alex Bastos and Thomas Schaefer, 2005-08-29 * Changes/fixes for drivers/cfi_flash.c: We *should* check if there are any error bits if the previous call returned ERR_OK (Otherwise we will have output an error message in flash_status_check() already.) The original code would only check for error bits if flash_status_check() returns ERR_TIMEOUT. Patch by Marcus Hall, 23 Aug 2005 * Changes/fixes for drivers/cfi_flash.c: - Add CFG_FLASH_PROTECT_CLEAR on drivers/cfi_flash.c - Prohibit buffer write when buffer_size is 1 on drivers/cfi_flash.c Patch by Sangmoon Kim, 19 Aug 2005 * Fixes for drivers/cfi_flash.c: - Fix wrong timeout value usage in flash_status_check() - Round write_tout up when converting to msec in flash_get_size() - Remove clearing flash status at the end of flash_write_cfibuffer() which sets Intel 28F640J3 flash back to command mode on CSB472 Patch by Tolunay Orkun, 02 July 2005 --- CHANGELOG | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) (limited to 'CHANGELOG') diff --git a/CHANGELOG b/CHANGELOG index 44989b849d..5e4d0770d2 100644 --- a/CHANGELOG +++ b/CHANGELOG @@ -2,6 +2,45 @@ Changes since U-Boot 1.1.4: ====================================================================== +* Add env-variable "unlock" to handle initial state of sectors + (locked/unlocked). + + Only the U-Boot image and it's environment is protected, + all other sectors are unprotected (unlocked) if flash + hardware protection is used (CFG_FLASH_PROTECTION) and + the environment variable "unlock" is set to "yes". + + Patch by Stefan Roese, 28 Feb 2006 + +* Update drivers/cfi_flash.c: + - find_sector() called in both versions of flash_write_cfiword() + Patch by Peter Pearse, 27th Feb 2006 + +* CFI support for a x8/x16 AMD/Spansion flash configured in x8 mode + Patch by Jose Maria Lopez, 16 Jan 2006 + +* Add support for AMD/Spansion Flashes in flash_write_cfibuffer + Patch by Alex Bastos and Thomas Schaefer, 2005-08-29 + +* Changes/fixes for drivers/cfi_flash.c: + We *should* check if there are any error bits if the previous call + returned ERR_OK (Otherwise we will have output an error message in + flash_status_check() already.)
