* NAND: Do not write or read a whole block if it is larger than the environmentGuennadi Liakhovetski2008-08-12-9/+9
| | | | | | | | Environment can be smaller than NAND block size, do not need to read a whole block and minimum for writing is one page. Also remove an unused variable. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>

| * NAND: Fix warning due to missing env_ptr casts to u_char * in env_nand.c.Marcel Ziswiler2008-07-09-4/+4
| | | | | | | | | | | | | | | | | | | | The writeenv() and readenv() calls introduced by the recently added bad block management for environment variables were missing casts therefore producing compile time warnings. While at it fixing some typo in a comment and indentation. Signed-off-by: Marcel Ziswiler <marcel@ziswiler.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* | Remove code duplication for setting the default environmentHarald Welte2008-07-10-13/+1
|/ | | | | | | | | | | common/env_common.c (default_env): new function that resets the environment to the default value common/env_common.c (env_relocate): use default_env instead of own copy common/env_nand.c (env_relocate_spec): use default_env instead of own copy include/environment.h: added default_env prototype Signed-off-by: Werner Almesberger <werner@openmoko.org> Signed-off-by: Harald Welte <laforge@openmoko.org>

* env_nand.c: Added bad block management for environment variablesStuart Wood2008-06-06-20/+99
| | | | | | | | | | Modified to check for bad blocks and to skipping over them when CFG_ENV_RANGE has been defined. CFG_ENV_RANGE must be larger than CFG_ENV_SIZE and aligned to the NAND flash block size.

* Cleanup nand_info[] declaration.Stelian Pop2008-05-28-3/+0
| | | | | | | | | The nand_info array is declared as extern in several .c files. Those days, nand.h contains a reference to the array, so there is no need to declare it elsewhere. Signed-off-by: Stelian Pop <stelian@popies.net> Signed-off-by: Scott Wood <scottwood@freescale.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-1/+1
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

* common/: Remove lingering references to CFG_CMD_* symbols.Jon Loeliger2007-07-10-1/+1
| | | | | | | | Fixed some broken instances of "#ifdef CMD_CFG_IDE" too. Those always evaluated TRUE, and thus were always compiled even when IDE really wasn't defined/wanted. Signed-off-by: Jon Loeliger <jdl@freescale.com>

| | | | | | | | | | | | | | This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely. All transformations are of the form: Before: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) After: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT) Signed-off-by: Jon Loeliger <jdl@freescale.com>
