* defaultenv-2: Make use of nonvolatile variablespu/persistent-varsSascha Hauer2014-11-0675-225/+84
| | | | | | | | | | | | | | This moves the variable assignments previously done in /env/config-board to non volatile variables in /env/nv/. This makes the settings adjustable by the user without editing a file. Most of the changes are simple conversions which for many boards makes /env/config-board unnecessary. Some boards had some logic to assign global.boot.default based on the current bootsource. This has been moved to /env/init/bootsource. An additional check is added to not overwrite a nv.boot.default should it exist. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* globalvar: Add support for printing all global variablesSascha Hauer2014-11-063-0/+11
| | | | | | | | | 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 defaultenv commandSascha Hauer2014-11-063-0/+103
| | | | | | | This adds a command to explicitly restore the environment (or parts thereof) from the default environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add support for non volatile variablesSascha Hauer2014-11-069-3/+336
| | | | | | | | | | | | | | | 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>
* magicvar: Add support for dynamically added magicvarsSascha Hauer2014-11-061-13/+98
| | | | | | | | Add support to add a new magicvar using the magicvar command. This is useful for magicvars assigned and used only in the environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* environment: Only save changes to the defaultenvSascha Hauer2014-11-062-14/+108

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The config option doesn't make any sense anymore when building a multiimage barebox.
