|
|
|
This driver get reboot mode arguments and call the write
|
|
interface to store the magic value in special register
|
|

|
|
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 none-zero value).
