* bootchooser: rename pr_setenv() to bc_setenv()Sascha Hauer2022-06-201-6/+6
| | | | | | | | We are about to introduce a generic function names pr_setenv(), so rename the existent bootchooser specific function to bc_setenv(). For consistency, rename pr_getenv() accordingly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* include: add dedicated header for printf/printkAhmad Fatoum2021-11-011-1/+1
| | | | | | | | | | | | Including <stdio.h> for printf is a bit problematic, because it pulls in other headers for <console.h>, which includes quite a few more headers as well. To make it easier to share code between barebox and host tools make <printk.h> the new minimal header for printf and move the extra logging stuff into <linux/printk.h>.

* | commands: implement and use parse_assignment helperAhmad Fatoum2020-11-271-3/+1
|/ | | | | | | | | | | | We have the split by '=' snippet at multiple locations that parse key=value pairs. Consolidate them to a single location. This makes code a bit easier to read at the cost of an extra 8 bytes (LZO-compressed THUMB2 barebox, static inline version is bigger). No functional change.

* magicvar: Replace BAREBOX_MAGICVAR_NAMED with BAREBOX_MAGICVARSascha Hauer2020-10-021-18/+12
| | | | | | | | BAREBOX_MAGICVAR now generates a unique identifier automatically, so we can convert users of BAREBOX_MAGICVAR_NAMED to the simpler BAREBOX_MAGICVAR macro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* treewide: Make locally used functions staticSascha Hauer2019-03-181-1/+1
| | | | | | | Many functions are only used locally but still are globally visible. Make these function static. Avoids warnings generated with -Wmissing-prototypes Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootchooser: Add reference countingSascha Hauer2018-10-181-5/+31
| | | | | | | | | | This adds reference counting to the bootchooser. Instead of creating a new bootchooser instance with each bootchooser_get() we return a reference to the existing bootchooser. This makes the behaviour consistent when bootchooser_get() is called multiple times. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootchooser: put bootchooser after creating a boot entrySascha Hauer2018-10-181-13/+23
| | | | | | | | | Between creating a boot entry for bootchooser and actually using it the underlying state may have been modified, so make sure to get a current bootchooser when booting it, thus do a bootchooser_put after having created the entry and a bootchooser_get again when booting it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootchooser: allow an empty namespaceJuergen Borleis2017-09-061-6/+4
| | | | | | | | | The bootchooser's documentation states the 'namespace' for the state storage backend is optional. This change makes it really optional to allow a flat state variable set definition for the 'bootchooser' as well.

* Revert "globalvar: make globalvar functions more consistent"Sascha Hauer2017-06-131-2/+2
| | | | This reverts commit 1b4a05c9263ae26083526acfabdea1ef96531a1d.
* globalvar: make globalvar functions more consistentSascha Hauer2017-04-111-2/+2
| | | | | | | | | Similar to the device parameter functions also make the globalvar functions more consistent. This also adds support for readonly globalvars and changes several existing globalvars which should really be readonly to readonly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootchooser: export bootchooser_bootSascha Hauer2017-04-061-7/+12
| | | | | | | | | Some boards that boot directly from C code do already know that they want to boot from bootchooser and nothing else. For these it's easiest to call bootchooser_boot directly, so export this function. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootchooser: register as bootentry providerSascha Hauer2017-04-061-2/+9
| | | | | | | | Instead of using a global function called by bootentry_create_from_name(), register the bootchooser as bootentry provider. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* boot: add framework for redundant boot scenariosMarc Kleine-Budde2016-09-221-0/+928
There are several use cases where a redundant Linux system is needed. The barebox bootchooser framework provides the building blocks to model different use cases without the need to start from the scratch over and over again. The bootchooser works on abstract boot targets, each with a set of properties and implements an algorithm which selects the highest priority target to boot. See the documentation contained in this patch for more information.
