* commands/*: Replace license and copyright boilerplate by SPDX identfiersUwe Kleine-König2020-04-271-16/+2
| | | | | | | | | | | | | While at it also drop references to the non-existing CREDITS file and do some small rearrangements for some uniform formatting. (SPDX-License-Identifier first, then copyright texts and then an empty line.) The advantage is that these specifiers are machine-parseable which helps license conformance.

* saveenv: Fix saving to specified fileSascha Hauer2014-10-231-6/+6
| | | | | | | | Since e805b7d saveenv: provide a zeroed/empty/ignore environment barebox no longer honors the file argument when the directory argument is also givin. Fix this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: saveenv: Fix comment about directories in help textSascha Hauer2014-08-011-2/+1
| | | | | | | | | | | | envfs indeed handles directories, at least since 2007: | commit 913691eccd13c1509470eb8b059aa0beecc6d8d8 | Author: Sascha Hauer <s.hauer@pengutronix.de> | Date: Tue Sep 25 12:58:52 2007 +0200 | | add directory handling for environment Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* saveenv: provide a zeroed/empty/ignore environmentJuergen Borleis2014-08-011-8/+22
| | | | | | | | | | | | If an external environment storage should be used in very rare and special cases, the intentional behaviour should be to ignore the external environment and always fall back to the built-in environment. By storing an empty "to be ignored" environment into the external environment a confusing error message about invalid CRC sums will go away and still the built-in environment is used. With this new option we can force the intentional behaviour. Signed-off-by: Juergen Borleis <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* envfs: change API to be able to forward special flags into the envfs superblockJuergen Borleis2014-08-011-1/+1
| | | | | | | | | | In order to be able to mark an stored envfs image with special features (intentional ignore for example), we now can feed forward these flags. By forwarding a '0' for the flags nothing changes because the envfs superblock was already allocated with xzalloc.

* saveenv: make clear how to use the command's parametersJuergen Borleis2014-08-011-1/+1
| | | | | | | | Both parameters can be omitted and DIRECTORY can be omitted, but the DIRECTORY parameter requires the ENVFS parameter as well. Signed-off-by: Juergen Borleis <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Documentation: remove doxygen documentationSascha Hauer2014-06-261-18/+0

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does probably too much, but it's hard (and very cumbersome/time consuming) to break it out. What is does is this: * each command has one short description, e.g. "list MUX configuration" * made sure the short descriptions start lowercase * each command has one usage. That string contains just the options, e.g. "[-npn]". It's not part of the long help text. * that is, it doesn't say "[OPTIONS]" anymore, every usable option is listed by character in this (short) option string (the long description is in the long help text, as before) * help texts have been reworked, to make them - sometimes smaller - sometimes describe the options better - more often present themselves in a nicer format * all long help texts are now created with BUSYBOX_CMD_HELP_ macros, no more 'static const __maybe_unused char cmd_foobar_help[]' * made sure the long help texts starts uppercase * because cmdtp->name and cmdtp->opts together provide the new usage, all "Usage: foobar" texts have been removed from the long help texts * BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this is nicer in the source code * BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself * made sure no line gets longer than 77 characters * delibertely renamed cmdtp->usage, so that we can get compile-time errors (e.g. in out-of-tree modules that use register_command() * the 'help' command can now always emit the usage, even without compiled long help texts * 'help -v' gives a list of commands with their short description, this is similar like the old "help" command before my patchset * 'help -a' gives out help of all commands Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: group 'help' outputHolger Schurig2014-05-141-0/+1
| | | | | | | | | | | | | | | | | | | The old output of "help" was just producing a long list, that usually scrolled of the screen (even on a X11 terminal). This list is more compact, and also sorted by groups. The old output format (plus grouping) is now available with 'help -v'. Example: Information commands: ?, devinfo, help, iomem, meminfo, version Boot commands: boot, bootm, go, loadb, loads, loadx, loady, saves, uimage ...

* env: erase/protect in envfs_saveSascha Hauer2014-04-281-45/+1
| | | | | | So that the envfs_save is more useful outside of the saveenv command Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* environment: Use accessor functions for default environment pathSascha Hauer2014-01-271-1/+1
| | | | | | | | | default_environment_path only exists when CONFIG_ENV_HANDLING is enabled. Boards would have to #ifdef this if they wanted to use default_environment_path. Use accessor functions instead which can be ifdeffed on a single place. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* move prototypes for envfs_* to envfs.hSascha Hauer2013-01-201-1/+1
| | | | | | | environment.h is for environment variables, not for the environment storage (envfs), so move the prototypes to envfs.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Treewide: remove address of the Free Software FoundationSascha Hauer2012-09-171-3/+0
| | | | | | | The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Make errno a positive valueSascha Hauer2012-05-141-3/+3
| | | | | | | | | Normally errno contains a positive error value. A certain unnamed developer mixed this up while implementing U-Boot-v2. Also, normally errno is never set to zero by any library function. This patch fixes this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: remove struct command pointer from commandsSascha Hauer2012-02-271-1/+1

* environment: make default env path configurableSascha Hauer2011-04-121-1/+1
| | | | | | | | Normally the default path to save the environment is /dev/env0. However, we can't map a file in a fat filesystem to /dev/env0. So if we want to store the environment in a file in fat we have to make it configurable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Enable 'saveenv' for non eraseable mediaJuergen Beisert2009-11-191-2/+3
| | | | | | | | | 'close()' clobbers the 'errno' value from the erase command. So it must be done *after* the check for ENOSYS to ingnore it correctly. Signed-off by: Juergen Beisert <j.beisert@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
