/* 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.
