| * Kconfig: Create Kconfig symbol for NVVARSascha Hauer2016-04-281-2/+16
| | | | | | | | | | | | | | | | | | | | nvvar support not only needs globalvar, but also persistent environment storage. Add a separate default-y option which depends on ENV_HANDLING for this case. Make the option visible to let the user decide whether he wants to have this option and add a help text to make this decision easier. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | stdio: Replace FILE functions with filedescriptor functionsSascha Hauer2016-04-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have defined stdin, stdout and stderr as integer file descriptors, but normally they should be FILE *. Also fprintf, fputc and fputs take file descriptors instead of FILE *. As FILE * are inconvenient in the barebox environment replace the f* functions with the corresponding d* functions. dprintf is POSIX conform whereas dputc and dputs are barebox specific, but do not conflict with any stdc function. fgetc is unused and can be removed without replacing it.

| * | string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-3/+4
| |/ | | | | | | | | | | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* globalvar: Add support for printing all global variablesSascha Hauer2014-11-061-0/+5
| | | | | | | | | This could previously only be done with 'devinfo global'. While this is still possible this adds a more direct access via the globalvar command. This variant also adds a '*' in front of the variable if the corresponding non volatile variable exists. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add support for non volatile variablesSascha Hauer2014-11-061-0/+173
| | | | | | | | | | | | | | | 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>
* param: let dev_add_param return the newly created paramSascha Hauer2014-10-081-1/+6
| | | | | | | | dev_add_param creates a new parameter so it makes more sense to return it than to return an error code. Since the return value is hardly ever checked this is only a small patch. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* treewide: Add missing includesSascha Hauer2013-11-081-0/+1
| | | | | | | | A lot of files rely on include/driver.h including include/of.h (and this including include/errno.h. include the files explicitly so we can eventually get rid of including of.h from driver.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * globalvar: Do not modify already existing variablesSascha Hauer2013-09-271-0/+3
| | | | | | | | | | | | | | | | | | When globalvar_add_simple was called on previously existing variables then the value was overwritten, even when value was passed as NULL. Do not overwrite the value in this case which allows us to do a 'global' on the same variable multiple times without loosing the values. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* add 'global' commandSascha Hauer2012-05-141-0/+65
This implements global shell variable support. This is done by registering a new device named 'global', so global variables are just plain device parameters. Global variables are useful for storing the global state in the environment. Currently we do this by sourcing scripts instead of executing them which is quite limiting.
