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. |
