Abstract

Systems and methods are included for causing a computing device to boot by retrieving hardware information from a device tree and further properties by utilizing a native access method call identified in the device tree. The access method can allow for getting a property, getting a property length, or setting a property. A table within firmware can identify the method, which then can retrieve the property information from memory. This Device tree Runtime (“DTRT”) mechanism can allow the computing device to retrieve the hardware configuration and act as a power management interface for turning on the correct hardware and hardware properties on the computing device.
