2017-08-15Move environment files from common/ to env/Simon Glass1-179/+0
About a quarter of the files in common/ relate to the environment. It seems better to put these into their own subdirectory and remove the prefix. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-07-22env: Switch env_nand, env_mmc and env_ubi to env_import_redundFiach Antaw1-37/+2
The env_nand, env_mmc and env_ubi implementations all implement redundancy using an identical serial-number scheme. This commit migrates them to use the implementation in env_common, which is functionally identical.

2016-06-13common: env_ubi: Clear environment buffer before readingMarcin Niestroj1-0/+21
In case we have restarted u-boot there is a chance that environment buffer contains old environment (from the previous boot). If UBI volume is zero size, ubi_volume_read() doesn't modify the buffer and exits successfully. We need to clear buffer manually before reading it from UBI, so the invalid CRC will cause setting default environment in case that the UBI volume is zero size.

2015-11-19env_ubi.c: Correct pointer error in env loadKevin Smith1-2/+1
The variable "buf" in this function is a char array, and the function ubi_volume_read is expecting a char *. In the call, the address of the pointer is being taken, incorrectly passing a char **. The compiler warning was being silenced by the cast. Remove the address operator and the cast.

2015-09-11Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h headerSimon Glass1-0/+1
Now that we have a new header file for cache-aligned allocation, we should move the stack-based allocation macro there also. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-03-21env: Add env_export() wrapperMarek Vasut1-19/+8
Implement env_export() wrapper, so that all implementers of saveenv() don't have to call hexport_r(), crc32() etc. sequence . This trims down a bit of code duplication. Signed-off-by: Marek Vasut <marex@denx.de>

Allow the user to specify two UBI volumes to use for the environment Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2013-04-11env: Add support for UBI environmentJoe Hershberger1-0/+103
UBI is a better place for the environment on NAND devices because it handles wear-leveling and bad blocks. Gluebi is needed in Linux to access the env as an MTD partition. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
