[PATCH v3 0/4] Add boot slot locking to bootchooser

[Lars Schmidt <l.schmidt@pengutronix.de>]

This patch series adds an option to lock attempts to bootchooser.
When slots are locked, the remaining_attempts counter will not
get counted down. It is optional, so when not set, it does not
have any effect on the counter. The choice of which slot to boot
is also not affected.
