[U-Boot] [PATCH 0/6] miscellaneous ubispl and ubi improvements

[Markus Klotzbuecher]

From: Markus Klotzbuecher <markus.klotzbuecher at kistler.com>

Hello Heiko and Kyungmin

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.

I also moved the ubispl config to Kconfig. There seem to be two boards
that use this (Maintainers cc'ed on patch). I have not updated their
defconfigs (not being sure if I should) but would be pleased to do so.

Hamish Guthrie (2):
  env: ubi: support configurable VID offset
  ubispl: add support for loading volumes by name

Markus Klotzbuecher (4):
  env: ubi: KConfig: add CONFIG_ENV_UBI_VOLUME_REDUND
  ubi: fix UBI_SILENCE_MSG
  ubispl: migrate configuration to Kconfig
  ubispl: introduce separate CONFIG_UBI_SPL_SILENCE_MSG
