2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-11-21env: Remove CONFIG_ENV_AES supportTom Rini
This support has been deprecated since v2017.09 due to security issues. We now remove this support. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-08-16env: Rename setenv() to env_set()Simon Glass
We are now using an env_ prefix for environment functions. Rename setenv() for consistency. Also add function comments in common.h. Suggested-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Simon Glass <sjg@chromium.org>
2017-04-12env: fix memory leak in fw_env routinesStefano Babic
fw_env_open allocates buffers to store the environment, but these buffers are never freed. This becomes quite nasty using the fw_ tools as library, because each access to the environment (even just reading a variable) generates a memory leak equal to the size of the environment. Fix this renaming fw_env_close() as fw_env_flush(), because the function really flushes the environment from RAM to storage, and add a fw_env_close function to free the allocated resources.

2017-04-12env: add a version number to check APIStefano Babic
Changes in the environment library are difficult to tracked by programs using the library. Add simply an API version number that must be increased each time when the API is changed. This can be detected and a program can work with different versions of the library. Signed-off-by: Stefano Babic <sbabic@denx.de>
2017-04-12env: split fw_env.h in public and private partsStefano Babic
Move U-Boot private data into a separate file. This lets export fw_env.h to be used by external programs that want to change the environment using the library built in tools/env. Signed-off-by: Stefano Babic <sbabic@denx.de>
2017-04-12Rename aes.h to uboot_aes.hStefano Babic
aes.h is a too generic name if this file can be exported and used by a program. Rename it to avoid any conflicts with other files (for example, from openSSL). Signed-off-by: Stefano Babic <sbabic@denx.de>
2016-10-08env: tool: add command line option to input lockfile pathB, Ravi
The default lockname is set to /var/lock. This limits the usage of this application where OS uses different lockfile location parameter. For example, In case of android, the default lock path location is /data. Hence by providing the command line option to input lockfile path will be useful to reuse the tool across multiple operating system. usage: ./fw_printenv -l <lockfile path> Signed-off-by: Ravi Babu <ravibabu@ti.com>
2016-07-22tools/env: kernel-doc for fw_printenv, fw_getenv and fw_parse_scriptAndreas Fenkart
there are two groups of functions: - application ready tools: fw_setenv/fw_getenv/fw_parse_script these are used, when creating a single binary containing multiple tools (busybox like) - file access like: open/read/write/close above functions are implemented on top of these. applications can use those to modify several variables without creating a temporary batch script file tested with "./scripts/kernel-doc -html -v tools/env/fw_env.h" Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Andreas Fenkart <andreas.fenkart@digitalstrom.com>

2016-02-08tools: env: introduce setenv/printenv argument structsAndreas Fenkart
goal is to use getopt for all argument parsing instead of adhoc parsing in fw_getenv/fw_setenv functions Signed-off-by: Andreas Fenkart <andreas.fenkart@digitalstrom.com>
2015-06-18tools/env/fw_env.h: Correct include orderPeter Robinson
When building tools-only (or env) we need to be sure that we do use <linux/kconfig.h> and do not use <generated/autoconf.h>. This will fix problems such as running 'make defconfig' or 'make sandbox_config' and then 'make tools-only'. Based on the responses below to the thread add linux/kconfig.h higher in the includes and drop the now unneeded autoconf.h lower down to ensure the default environment is included correctly http://lists.denx.de/pipermail/u-boot/2015-June/216849.html Signed-off-by: Peter Robinson <pbrobinson@gmail.com>
2015-05-05fw_env.h: include autoconf.hMax Krummenacher
Without this, when CONFIG_ENV_VARS_UBOOT_CONFIG is active we get a compile time error when doing 'make env'.

2012-10-15tools/env: Use a board-specific default envJoe Hershberger
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>

2011-06-22ARM: drop unsupported 'trab' boardWolfgang Denk
The 'trab' board configuration is broken, and there is nobody who is interested and willing to fix it. Drop it. This includes support for VFD displays which have always been used by this board only. Signed-off-by: Wolfgang Denk <wd@denx.de>
2011-04-12Add support for dataflash to U-boot environment settings tool.Remy Bohmer
* The sector size for SPI-dataflash (like AT45 flashes) are not always a power-of-2. So, the sector calculations are rewritten such that it works for either power-of-2 as any size sectors. * Make the flash sector size optional in case it is the same value as the environment size.

2010-06-29Tools: set multiple variable with fw_setenv utilityStefano Babic
Add a sort of batch mode to fw_setenv, allowing to set multiple variables in one shot, without updating the flash after each set as now. It is added the possibility to pass a config file with a list of pairs <variable, value> to be set, separated by a TAB character. Signed-off-by: Stefano Babic <sbabic@denx.de>
2008-05-21Big white-space cleanup.Wolfgang Denk
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>
2008-05-09Propagate Error Status to the Shell on fw_printenv ErrorsGrant Erickson
Changed implementation such that fw_printenv returns failure status when one or more specified variables do not exist or when incorrect command syntax is used. This aids scripting fw_printenv such that the script can key of the return status rather than relying on standard error "scraping".

2008-01-08tools: fix fw_printenv tool to compile againMarkus Klotzbücher
This patch updates the fw_printenv/fw_setenv userspace tool to include the correct MTD header in order to compile against current kernel headers. Backward compatibility is preserved by introducing an option MTD_VERSION which can be set to "old" for compilation using the old MTD headers. Along with this a number of warnings are fixed.

2005-11-20Change all '$(...)' variable references into '${...}'Wolfgang Denk
which makes the environment compatible with the hush shell. WARNING: Support for the old '$(...)' syntax will be discontinued in a later version.
2003-06-27* Code cleanup:wdenk
- remove trailing white space, trailing empty lines, C++ comments, etc. - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c) * Patches by Kenneth Johansson, 25 Jun 2003: - major rework of command structure (work done mostly by Michal Cendrowski and Joakim Kristiansen)
2003-04-20* Make sure Block Lock Bits get cleared in R360MPI flash driverwdenk
* MPC823 LCD driver: Fill color map backwards, to allow for steady display when Linux takes over * Patch by Erwin Rol, 27 Feb 2003: Add support for RTEMS (this time for real). * Add support for "bmp info" and "bmp display" commands to load bitmap images; this can be used (for example in a "preboot" command) to display a splash screen very quickly after poweron. * Add support for 133 MHz clock on INCA-IP board
2003-01-11* Restrict baudrate settings on LWMON to higher speedswdenk
when watchdog is on * Update baudrate in bd_info when it gets changed * Add watchdog trigger points while waiting for serial port (so far only 8xx -- needed on LWMON with 100ms watchdog) * Improve command line tool to access the U-Boot's environment (figuration of the utility, using a config file)
2002-12-17* Use 1-byte-read instead of -write for iprobe() functionwdenk
Add i2c commands to PM826 config * extend I2C POST code: check for list on known addresses
