Subject: Re: AJB wake up in car application

I've actually done this myself.

The settings are not all saved in RTC. Some are saved on disk.
So the settings are loaded after the disk check. Simply add
one more setting load before charging screen is useless because,
unfortunately, the car mode setting is saved on disk. So I have
to exchanged the car mode setting with flip_display setting,
which is saved in RTC. By doing that, you save the car mode
setting in RTC. Load settings before charging screen and add a
check before entering.

I think powering up when power returns is more reasonable in
car adapter mode.
