| description: | |
| 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. |
