* login: rework login mechanismSascha Hauer2015-08-281-3/+0
| | | | | | | | | | | | | | 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.

* PBL: console: Make independent of DEBUG_LLSascha Hauer2015-07-311-0/+6
| | | | | | | | | | With more stuff being done in PBL regular console support gets more and more useful. This makes the PBL console independent of DEBUG_LL which is only meant for early debugging but not regular output. To use the regular PBL console a board must call pbl_set_putc() which stores a pointer to the putc function to be used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: Add console_get_by_nameSascha Hauer2015-06-091-0/+1
| | | | | | | Commands like loadx/loady wish to find a console device by its name. Add a function for this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: Add functions to get/set baudrateSascha Hauer2015-06-091-0/+3
| | | | | | So C code can call a function rather than fiddling with device parameters. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: Add functions to get/set active state of consoleSascha Hauer2015-06-091-0/+4
| | | | | | | | Currently code needs to fiddle with the active parameter of a console device directly to enable/disable consoles. Add console_set_active() to set the status and console_get_active() to get the current status. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: allow to specify the device idJean-Christophe PLAGNIOL-VILLARD2015-01-131-0/+1

* console: Add set_active callbackSascha Hauer2014-12-171-0/+1
| | | | | | | | The netconsole needs to be able to deny activation when the network has not been enabled. Add an optional callback to the console for this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * console: Add puts callback to console devicesSascha Hauer2014-07-111-0/+1
| | | | | | | | | | | | | | | | Some devices may have a much more efficient way to output strings rather than single characters. Let console devices implement a callback for this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | console: Allow persistent device namesSascha Hauer2014-07-111-0/+2
|/ | | | | | | | Add a devname field to struct console_device so that the device name can be set by the driver. This makes it possible to have persistent device names. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: Set Linux console parameter automaticallySascha Hauer2014-01-221-0/+2
| | | | | | | | | | | | | | | | | | | | | Linux specifies the linux,stdout-path property in the /chosen node in the devicetree. Unfortunately this is ignored in most cases. For cases in which barebox uses this property for its own use we translate this into a Linux boot arg with: - the console name provided by the serial driver - the the instance from the 'serial' alias - the baudrate from the actual baudrate. So with this it's for devicetee enabled boards no longer necessary to manually assign a console= parameter. Should a user not want to use the automatically assigned parameter it should do: global.linux.bootargs.console= in the environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* rework device parametersSascha Hauer2010-06-171-6/+0
| | | | | | | | Change device parameters so that the memory management is in generic code. This also removes the need of storing statically initialized parameters as they are stored in a struct list_head for each device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
