This series contains a couple of UBI and UBI SPL improvements, notably a ubispl extension to allow loading volumes by name. The motivation is to use the UBI atomic volume rename functionality to allow double copy software updates of U-Boot on UBI. To do that we configured the SPL to always load the same volume name (e.g. "u-boot"), and the software updater always installs into the secondary volume "u-boot_r". After a successful upgrade, these two volume names are switched.
This extension is protected by #ifdefs as it will somewhat slow down loading of volumes by id. This is because the code needs to disable the optimization of ignoring all volume ids which are not to-be-loaded, since these can only be resolved after attaching.
We have tested both with and without fastmap enabled and both paths seems to work reliably.
As per Heikos request, this v2 adds two patches that migrate the omap2plus and at91 CONFIG_ENV_* to defconfigs and likewise for the two boards using ubispl. The first migration was supported by an extension to the moveconfig script (patch 1) to expand simple expressions. Both migrations were tested to be binary equal before and after the change.
Changes v2:
- Add a patch (1) for moveconfig to expand simple expressions
- Add patch (3) to move at91 and omap2plus CONFIG_ENV_ to defconfigs
- Add patch (7) to migrate boards using ubispl to KConfig
- Add missing commit messages
- Indicate version of kernel code which was used in ubispl
I don't mean to bug, just wanted to ask if there's anything missing for this v2 series...
Thanks, Markus
