* env_mmc: allow negative CONFIG_ENV_OFFSETStephen Warren2013-06-13-2/+10
| | | | | | | | | | | | | | | | A negative value of CONFIG_ENV_OFFSET is treated as a backwards offset from the end of the eMMC device/partition, rather than a forwards offset from the start. This is useful when a single board may be stuffed with different eMMC devices, each of which has a different capacity, and you always want the environment to be stored at the very end of the device (or eMMC boot partition for example). One example of this case is NVIDIA's Ventana reference board. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* env_mmc: add support for redundant environmentMichael Heimpold2013-05-01-9/+123
| | | | | | | | This patch add support for storing the environment redundant on mmc devices. Substantially it re-uses the logic from the NAND implementation, that means using an incremental counter for marking newer data. Signed-off-by: Michael Heimpold <mhei@heimpold.de>
* Revert "env: fix potential stack overflow in environment functions"Tom Rini2013-04-05-7/+6
| | | | | | | | | | Wolfgang requested this be reverted and Rob agreed after further discussion. This was a symptom of a larger problem we need to deal with. This reverts commit 60d7d5a63189c9f77a190c9965861dc15482c2d0. Signed-off-by: Tom Rini <trini@ti.com>
* env: fix potential stack overflow in environment functionsRob Herring2013-04-02-6/+7
| | | | | | | | | Most of the various environment functions create CONFIG_ENV_SIZE buffers on the stack. At least on ARM and PPC which have 4KB stacks, this can overflow the stack if we have large environment sizes. So move all the buffers off the stack to static buffers.

* env: Hide '.' variables in env print by defaultJoe Hershberger2012-12-13-1/+1
| | | | | | | | | | When printing all variables with env print, don't print variables that begin with '.'. If env print is called with a '-a' switch, then include variables that begin with '.' (just like the ls command). Variables printed explicitly will be printed even without the -a. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* 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: 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

* 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

* 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>

| | | | | | | | | | | | | | | | | | | | | | 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.
