1. Change u-boot environment:

    $ factory (load|set|save|list) [variable] [value]

Set without value to unset the env variable.
You could do multiple set command before save.

Ex: ./factory load
    ./factory set
 
 nasargs loglevel=7
    ./factory save


2. Set flag:

    $ factory (flag|unflag) FLAGNAME

Ex: ./factory flag SHUTDOWN


3. Set RTC alarm，

    $ factory alarm (read|set) [timestamp]

Set without timestamp to clear alarm.

timestamp format:
YYYYMMDDhhmmss
YYYY-MM-DD hh:mm:ss
YYYY-MM-DD hh:mm      (seconds
 
 will be set to 00)
YYYY-MM-DD            (time will be set to 00:00:00)
hh:mm:ss              (date will be set to today)
hh:mm                 (date will be set to today, seconds to 00)
tomorrow              (time is set to 00:00:00)
+5min

Ex: ./factory alarm set +5min

On RTC alarm set, the timestamp value will be written into
 
 the file
named RTC in factory on RTC alarm set.
And the RTC file will be removed on alarm reset.
