* include: move shell prototypes to shell.hSascha Hauer2016-04-151-0/+1
| | | | | | We have a shell,h, so move shell specific prototypes there. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fs: Add pstore filesystemMarkus Pargmann2015-12-101-0/+5
| | | | | | | | | | | | | | | | pstore is a persistent storage filesystem used for RAMOOPS. It is used to store console logs, panics, ftrace and other information in case of a crash/panic/oops/reboot. pstore is implemented for barebox as a read-only filesystem at the moment. It may be extended later on. The idea is to provide a way to extract essential data from the last running kernel. Most of the code is copied from the kernel. However this is only a lightweight implementation without real write support yet. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* login: rework login mechanismSascha Hauer2015-08-281-5/+2
| | | | | | | | | | | | | | We used to have the login functionality in the /env/bin/init script. This is hard to review and it's too easy to break the login functionality with changes to this script. Move the places to ask for a password to C code where we have only a few places where we have to ask for a password. Mainly these are run_shell() and the menutree command. This patch introduces a login() function which will only return if the correct password has been entered. Following calls will return immediately without asking for a password again.

* Add support for non volatile variablesSascha Hauer2014-11-061-0/+2
| | | | | | | | | | | | | | | This adds (back) support for non volatile variables. Non volatile variables are variables which are stored in the environment over reboot. They are used in the same way as the global variables, but with a 'nv' command and device. The variables are stored under /env/nv/, one variable per file. Adding a nv variable automatically adds a global variable with the same name. Changing a nv variable also changes the same global variable, but not the other way round. This allows for example to configure the username as: nv user=sha; saveenv Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | Similar to mount(8) the barebox command mount now supports passing a string to the file system driver via -o.

* | defaultenv: Allow multiple defaultenvironment overlaysSascha Hauer2014-02-281-34/+1
| | | | | | | | | | | | | | | | | | | | We can compile barebox for multiple boards at once, but currently they all share a single default environment. This patch adds a defaultenv_append() which boards can call to customize the default environment during runtime. Each board now generate default environment snippets using bbenv-y and add them during runtime with defaultenv_append() Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | defaultenv: Align defaultenv arraySascha Hauer2014-02-201-10/+1
| | | | | | | | | | | | | | | | | | | | The default environment buffer is an unsigned char array and thus may be unaligned. Some decompression algorithms expect the buffer to be sufficiently aligned for u32 accesses. We make this sure by copying the default env to a temporary buffer. Instead of doing this just add a __aligned(4) to the default environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | Kconfig: Select default compression typeSascha Hauer2014-02-191-1/+1
|/ | | | | | | | | | Instead of asking explicitly for the default environment compression type ask for the in-barebox default compression type. This also adds a DEFAULT_COMPRESSION_SUFFIX make variable which can be used together with the wildcard rules for compressed files to generate compressed files without explicitly support each compression type.

* environment: Use accessor functions for default environment pathSascha Hauer2014-01-271-0/+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>

* startup: call a barebox_main function pointer at the end of the startupSascha Hauer2013-01-201-1/+12
| | | | | | | | | | | | | | | | | Currently Kconfig dependencies are used to allow non-interactive builds. This leads to problems in Kconfig getting the dependencies right. This patch adds a barebox_main function pointer which is called at the end of the startup process. This defaults to run_shell when a shell is enabled. With this the HAVE_NOSHELL Kconfig variable can be removed. Non interactive builds can now be enabled for every board allowing to compile a binary without further Kconfig dependencies. This also allows for more flexibility, for example boards may decide to try non-interactive startup first and call run_shell if that fails. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* loadenv: allow more fine grained environment loadingSascha Hauer2012-11-291-2/+2
| | | | | | | | | | | This implements two new options for the loadenv command: -s: removes (scrubs) old directory contents to be able to create a fresh environment from for example /dev/defaultenv -n: no overwrite. Do not overwrite existing files. This allows to keep parts of the old environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * startup: Print error message when initcall failsSascha Hauer2012-10-091-1/+3
| | | | | | | | | | | | | | | | | | | | There was a time when we used to panic when initcalls failed. Then it was changed to totally ignore the return value. Instead, print an error message now so that the user can get a clue when something bad happened. So initcalls are now recommended to actually return negative error codes when something fails.

* | defaultenv: dependencies fixesSascha Hauer2012-10-121-1/+1
|/ | | | | | | | | | | | | | When a build with a compressed default environment is done and then environment compression is disabled, barebox_default_env.h is not regenerated because its dependency (now barebox_default_env) is still up to date. This results in a corrupt default environment. This patch fixes this by adding a cmd_env_h and changing barebox_default_env.h to FORCE. As a side effect barebox_default_env.h is no longer generated in include/generated/ but in common/ as we have to add barebox_default_env.h to $(targets) (extra-y).
