| * env: Implement support for AES encryption into fw_* toolsMarek Vasut2014-03-21-2/+127
| | | | | | | | | | | | | | | | | | | | | | | | Implement support for encrypting/decrypting the environment block into the tools/env/fw_* tools. The cipher used is AES 128 CBC and the implementation depends solely on components internal to U-Boot. To allow building against the internal AES library, the library did need minor adjustments to not include U-Boot's headers which are not wanted to be included and define missing types.

* | fw_env.c: Switch get_config to use '%ms' in sscanfTom Rini2014-04-17-5/+8
|/ | | | | | | | | | We currently limit ourself to 16 characters for the device name to read the environment from. This is insufficient for /dev/mmcblk0boot1 to work for example. Switch to '%ms' which gives us a dynamically allocated buffer instead. We're short lived enough to not bother free()ing the buffer. Signed-off-by: Tom Rini <trini@ti.com>
* fw_env: correct writes to devices with small erase blocksDustin Byford2014-03-12-2/+2
| | | | | | | | | | | | | | | | | Some NOR flash devices have a small erase block size. For example, the Micron N25Q512 can erase in 4K blocks. These devices expose a bug in fw_env.c where flash_write_buf() incorrectly calculates bytes written and attempts to write past the environment sectors. Luckily, a range check prevents any real damage, but this does cause fw_setenv to fail with an error. This change corrects the write length calculation. The bug was introduced with commit 56086921 from 2008 and only affects configurations where the erase block size is smaller than the total environment data size.

* fw_env: calculate default number of env sectorsDustin Byford2014-03-12-6/+8
| | | | | | | | | | | | | | | The assumed number of environment sectors (always 1) leads to an incorrect top_of_range calculation in fw.env.c when a flash device has an erase block size smaller than the environment data size (number of environment sectors > 1). This change updates the default number of environment sectors to at least cover the size of the environment. Also corrected a false statement about the number of sectors column in fw_env.config.

* tools/env: Add environment variable flags supportJoe Hershberger2012-12-13-0/+9
| | | | | | | | | | | | | | Currently just validates variable types as decimal, hexidecimal, boolean, ip address, and mac address. Call env_acl_validate_setenv_params() from setenv() in fw_env.c. If the entry is not found in the env .flags, then look in the static one. This allows the env to override the static definitions, but prevents the need to have every definition in the environment distracting you. Need to build in _ctype for isdigit for Linux.

* tools/env: Use a board-specific default envJoe Hershberger2012-10-15-15/+13
| | | | | | | | | | | | | | | | | | | Originally added in aa701b94336b358798d676eef12a7b90bdac23f5 Before this patch, there was a hard-coded env that was used as default if the env in flash is detected as invalid. Now this tool (compiled for a given board) will share the default env with the u-boot for the board. Fix include of config.h Need to define "TEXT_BASE" when building the fw_env tool so that the default env will be correct for environments which use it. Define __ASSEMBLY__ when calling #include <config.h> so that we only get #defines (all we're interested in). Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

* tools/env: fix redundant env flag comparisonJon Povey2011-04-21-7/+6
| | | | | | | | | | | | | | | | | | This fixes two bugs with comparison of redundant environment flags on read. flag0 and flag1 in fw_env_open() were declared signed instead of unsigned char breaking BOOLEAN mode "== 0xFF" tests and in INCREMENTAL mode the wrong environment would be chosen where the flag values are 127 and 128 (either way round). With both flags over 128, both signs flipped and the logic worked by happy accident. Also there was a logic bug in the INCREMENTAL test (after signedness was fixed) in the case flag0=0, flag1=255, env 1 would be incorrectly chosen. Fix both of these.
