| This driver get reboot mode arguments and call the write | |
| interface to store the magic value in special register | |
| or ram. Then the bootloader can read it and take different | |
| action according to the argument stored. | |
| All mode properties are vendor specific, it is a indication to tell | |
| the bootloader what to do when the system reboots, and should be named | |
| as mode-xxx = <magic> (xxx is mode name, magic should be a non-zero value). | |
| For example, modes common Android platform are: | |
| - normal: Normal reboot mode, system reboot with command "reboot". | |
| - recovery: Android Recovery mode, it is a mode to format the device or update a new image. | |
| - bootloader: Android fastboot mode, it's a mode to re-flash partitions on the Android based device. | |
| - loader: A bootloader mode, it's a mode used to download image on Rockchip platform, | |
| usually used in development. | |
