* setenv: Be more informative when device parameter setting failsSascha Hauer2015-05-041-5/+7
| | | | | | | | | When setting a device parameter fails not only the error code is of interest, but also what the parameter name is, what the device name is and whether a device was found for this name. Add this information to the error message. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* timeout: factor out wait-for-key-press loop into separate fileMarc Kleine-Budde2015-04-232-0/+68
| | | | | | | | This patch factors out the wait-for-key-press loop from the shell command "timeout" into a sparate file, so that it can be used from C, too. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * state: add framework for persistent state handlingSascha Hauer2015-03-123-0/+1206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a framework to describe, access, store and restore a set of variables. A state variable set can be fully described in a devicetree node. This node could be part of the regular devicetree blob or it could be an extra devicetree solely for the state. The state variable set contains variables of different types and a place to store the variable set.

|/ | | | | | | | | | | | | | | | | | | PBL_CONSOLE option is used only for building PBL.

To handle this gracefully, we extend the data abort exception handler to ignore the exception when configured to do so. This allows detecting inaccessible memory from the md command. It will show XX for unreadable bytes instead.
