* env_mmc: allow environment to be in an eMMC partitionStephen Warren2012-09-05-8/+56
| | | | | | | | | | | | | eMMC devices may have hardware-level partitions: 2 boot partitions, up to 4 general partitions, plus the user area. This change introduces optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which partition the environment should be stored in: 0=user, 1=boot0, 2=boot1, 4..7=general0..3. This allows the environment to be kept out of the user area, which simplifies the management of OS-/user-level (MBR/GPT) partitions within the user area.

* env_mmc: align buffers using ALLOC_CACHE_ALIGN_BUFFERStephen Warren2012-07-07-5/+5

* env: factor out the env_get_char_spec() functionIgor Grinberg2012-01-05-5/+0
| | | | | | | | | env_get_char_spec() function is duplicated across multiple environment files. Remove the duplication by providing a default implementation. Add "weak" declaration, so the default implementation can be overridden. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>
* env: clean env_mmc.c checkpatch and code styleIgor Grinberg2011-11-22-49/+23
| | | | | | | | Cleanup the env_mmc.c checkpatch warnings, errors and coding style. Simplify env_relocate_spec() function implementation. Also mark internal functions as static. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>

* env: allow to export only selected variablesWolfgang Denk2011-11-08-1/+1
| | | | | | | | | | | | | | New syntax: env export [-t | -b | -c] [-s size] addr [var ...] With this change it is possible to provide a list of variables names that shall be exported. Whenno arguments are given, the whole environment gets exported. NOTE: The new handling of the "size" argument means a change to the user API. Signed-off-by: Wolfgang Denk <wd@denx.de>
* env_mmc: Allow board code to override the environment addressMingkai Hu2011-04-04-4/+27
| | | | | | | | | | | | On some boards the environment may not be located at a fixed address in the MMC/SDHC card. This allows those boards to implement their own means to report what address the environment is located at.

* hashtable: drop all non-reentrant versionsMike Frysinger2010-12-17-1/+1
| | | | | | | | | | | The non-reentrant versions of the hashtable functions operate on a single shared hashtable. So if two different people try using these funcs for two different purposes, they'll cause problems for the other. Avoid this by converting all existing hashtable consumers over to the reentrant versions and then punting the non-reentrant ones. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * env_mmc: Fix crashing bug encountered after enabling ARM relocationSteve Sakoman2010-10-13-7/+10
| | | | | | | | | | | | | | | | | | | | | | The crash was occuring in env_relocate because it was being called prior to mmc_initialize. This patch moves the MMC initialization earlier in the init process. This patch also cleans up the env_relocate_spec code in env_mmc.c Signed-off-by: Steve Sakoman <steve.sakoman@linaro.org> Acked-by: Stefano Babic <sbabic@denx.de>
