/* Constructing the device tree:

|
The initial device tree populated with devices and basic properties

is created using the function <<device_tree_add_parsed()>>. This
|
||
|
function parses a PSIM device specification and uses it to populate
|

|
the tree accordingly.

This function accepts a printf style formatted string as the

argument that describes the entry. Any properties or interrupt
|

|
connections added to a device tree using this function are marked
|
||
|
as having a permenant disposition. When the tree is (re)
|
||
|
initialized they will be restored to their initial value.
