2009-06-04Redundant Environment: protect full sector sizeWolfgang Denk
Several boards used different ways to specify the size of the protected area when enabling flash write protection for the sectors holding the environment variables: some used CONFIG_ENV_SIZE and CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even a mix of both for the "normal" and the "redundant" areas. Normally, this makes no difference at all. However, things are different when you have to deal with boards that can come with different types of flash chips, which may have different sector sizes. Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the biggest sector size, which may include several sectors on boards using the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the case that only the first of these sectors get protected, while the following ones aren't. This is no real problem, but it can be confusing for the user - especially on boards that use CONFIG_ENV_SECT_SIZE to protect the "normal" areas, while using CONFIG_ENV_SIZE_REDUND for the "redundant" area. To avoid such inconsistencies, I changed all sucn boards that I found to consistently use CONFIG_ENV_SECT_SIZE for protection. This should not cause any functional changes to the code.

2006-07-19Fix some bugs in TRAB board flash driver.Wolfgang Denk
- increase CFG_FLASH_ERASE_TOUT from 2 to 15 seconds - use CFG_FLASH_WRITE_TOUT for programming instead of CFG_FLASH_ERASE_TOUT - remove "Unlock Bypass" mode, because macronix flashes do not support this mode officially - fix flash reset command from 0x00FF to 0x00F0. 0x00FF is only specified for Intel compatible flashes, not for AMD compatible.

2006-07-19Add additional error messages to flash driver on TRAB boardWolfgang Denk
(for erase errors and timeout errors) Patch by Martin Krause, 14 Feb 2006
2006-03-11More GCC 4.x code cleanupWolfgang Denk
2004-10-17Code cleanup for GCC-3.3.x compilerswdenk
2004-03-23* Add start-up delay to make sure power has stabilized beforewdenk
attempting to switch on USB on SX1 board. * Patch by Josef Wagner, 18 Mar 2004: - Add support for MicroSys XM250 board (PXA255) - Add support for MicroSys PM828 board (MPC8280) - Add support for 32 MB Flash on PM825/826 - new SDRAM refresh rate for PM825/PM826 - added support for MicroSys PM520 (MPC5200) - replaced Query by Identify command in CPU86/flash.c to support 28F160F3B * Fix wrap around problem with udelay() on ARM920T * Add support for Macronix flash on TRAB board
2003-11-17Fix flash driver for TRAB board (must use Unlock Bypass Reset commandwdenk
to exit Unlock Bypass Mode); adjust timings for flash, SRAM and CPLD
2003-06-27* Code cleanup:wdenk
- remove trailing white space, trailing empty lines, C++ comments, etc. - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c) * Patches by Kenneth Johansson, 25 Jun 2003: - major rework of command structure (work done mostly by Michal Cendrowski and Joakim Kristiansen)
2003-05-30* Get (mostly) rid of CFG_MONITOR_LEN definition; compute real lengthwdenk
instead CFG_MONITOR_LEN is now only used to determine _at_compile_ _time_ (!) if the environment is embedded within the U-Boot image, or in a separate flash sector. * Cleanup CFG_DER #defines in config files (wd maintained only)
2003-05-28* Fix data abort exception handling for arm920t CPUwdenk
* Fix alignment problems with flash driver for TRAB board * Patch by Donald White, 21 May 2003: fix calculation of base address in pci_hose_config_device() * Fix bug in command line parsing: "cmd1;cmd2" is supposed to always execute "cmd2", even if "cmd1" fails. Note that this is different to "run var1 var2" where the contents of "var2" will NOT be executed when a command in "var1" fails.
2003-03-12* Patch by Josef Wagner, 12 Mar 2003:wdenk
- 16/32 MB and 50/80 MHz support with auto-detection for IP860 - ETH05 and BEDBUG support for CU824 - added support for MicroSys CPC45 - new BOOTROM/FLASH0 and DOC base for PM826 * Patch by Robert Schwebel, 12 Mar 2003: Fix the chpart command on innokom board * Name cleanup: mv include/asm-i386/ppcboot-i386.h include/asm-i386/u-boot-i386.h s/PPCBoot/U-Boot/ in some files s/pImage/uImage/ in some files * Patch by Detlev Zundel, 15 Jan 2003: Fix '' command line quoting * Patch by The LEOX team, 19 Jan 2003: - add support for the ELPT860 board - add support for Dallas ds164x RTC
