6.4.13. System Restart Controllers

In addition to upstream bindings, following properties are understood:

Optional properties:

  • restart-priority : Overrides the priority set by the driver. Normally, the device with the biggest reach should reset the system. See System Restart for more information.

  • barebox,restart-warm-bootrom : Restart will not cause loss to non-volatile registers sampled by the bootrom at startup. This is a necessary precondition for working Reboot Mode communication between barebox and the SoC’s BootROM.
