Add a config option to reset system soon after processing capsule update on disk. This is required in UEFI specification 2.9 Section 8.5.5 "Delivery of Capsules via file on Mass Storage device" as;
In all cases that a capsule is identified for processing the system is restarted after capsule processing is completed.This also reports the result of each capsule update so that the user can notice that the capsule update has been succeeded or not from console log.
Signed-off-by: Masami Hiramatsu masami.hiramatsu@linaro.org
Changes in v2:
- Remove kconfig option to disable this feature.
- Use panic() instead of do_reset() so that if the reset fails, the machine halt.
- Log the result of each capsule update always.

Hmm, would you think to use log_info() even if it is failed? Or should we have log_err(failure) and log_info(success)?
It is what I meant :)
OK.

Indeed. Heinrich, what would you think if do_reset() doesn't work? (I think it is OK to get it back here, but needs a warning)
If (CONFIG_IS_ENABLED(SYSRESET)) { puts ("resetting ...\n"); sysreset_reset_walk(SYSRESET_WARM); } else { do_reset(...) halt(); } /* not reach here */
OK, and in both case we should we puts() some messages before reboot, right?
