Configure devices on the devices tree.
Starting at the root of the device tree, travel it recursively in two passes. In the first pass, we compute and allocate resources (ranges) required by each device. In the second pass, the resources ranges are relocated to their final position and stored to the hardware.
I/O resources grow upward. MEM resources grow downward.
Since the assignment is hierarchical we set the values into the dev_root struct.

Determine the existence of devices and extend the device tree.
Most of the devices in the system are listed in the mainboard devicetree.cb file. The device structures for these devices are generated at compile time by the config tool and are organized into the device tree. This function determines if the devices created at compile time actually exist in the physical system.
For devices in the physical system but not listed in devicetree.cb, the device structures have to be created at run time and attached to the device tree.
This function starts from the root device 'dev_root', scans the buses in the system recursively, and modifies the device tree according to the result of the probe.
This function has no idea how to scan and probe buses and devices at all. It depends on the bus/device specific scan_bus() method to do it. The scan_bus() method also has to create the device structure and attach it to the device tree.

Enable devices on static buses.
The enumeration of certain buses is purely static. The existence of devices on those buses can be completely determined at compile time and is specified in the config file. Typical examples are the 'PNP' devices on a legacy ISA/LPC bus. There is no need of probing of any kind, the only thing we have to do is to walk through the bus and enable or disable devices as indicated in the config file.
On the other hand, some devices are virtual and their existence is artificial. They can not be probed at run time. One example is the debug device. Those virtual devices have to be listed in the config file under some static bus in order to be enumerated at run time.
