Reboot property to control system reboot on PPC4xx systems: |
||||
|
||||
By setting "reset_type" to one of the following values, the default |
||||
software reset mechanism may be overidden. Here the possible values of |
||||
"reset_type": |
||||
|
||||
1 - PPC4xx core reset |
||||
2 - PPC4xx chip reset |
||||
3 - PPC4xx system reset (default) |
||||
|
||||
Example: |
||||
|
||||
cpu@0 { |
||||
device_type = "cpu"; |
||||
model = "PowerPC,440SPe"; |
||||
... |
||||
reset-type = <2>; /* Use chip-reset */ |
||||
}; |
