From: Andreas Reichel <[email protected]>
This patch series implements the new fail-safe mode.
As discussed on the mailing list, if fail-safe mode is enabled, only
environments on the boot-device are used. If not, all environments
found are used.
Fail-safe mode is enabled by setting the corresponding flag in ANY
environment on the boot medium.
This series does the following:
* Add some support functions
* Rename in_progress to env_status and reimplement in_progress
from uint8_t to a single bit within this new env_status
register.
* Add new failsafe flag into the env_status register.
* Fix some odd return values in bgenv_set / get, which
depended on the wrong value given
* Improve some error handling code
* Make travis-ci work again
* Update documentation
