* param_enum: Make name strings constSascha Hauer2015-08-261-2/+2
| | | | | | | | Not only the array containing the pointers should be const but also the strings themselves, so instead of using const char ** use const char * const *. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add globalvar_add_simple_string functionSascha Hauer2015-06-181-0/+19
| | | | | | | | This adds a globalvar string function to pass a pointer to a string. With this we can directly access the string to get the variable and don't have to getenv() the string first. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* globalvar: Add support for printing all global variablesSascha Hauer2014-11-061-0/+1
| | | | | | | | | 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/+12
| | | | | | | | | | | | | | | 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>

* globalvar: Allow to set initial valueSascha Hauer2013-08-161-2/+2
| | | | | | | Calling globalvar_add_simple() and setting a value is more than common. Add a parameter for the initial value. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* add 'global' commandSascha Hauer2012-05-141-0/+12
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.
