-   a.	The <<com>> device attaches its self to its parent <<phb>>
-   	device at address <<0x3f8>> through to address <<0x3f8 + 16>>.
-
-   b.   The <<phb>> has in turn attached its self to addresses
-        <<0xf0000000 .. 0xf0100000>>.
-
-   During the execution of the simulation propper, the following then
-   occure:
-	
-   1.	After any virtual to physical translation, the processor
-   	passes the address to be read (or written to the core device).
-	(eg address 0xf00003f8).
-
-   2.   The core device then looks up the specified addresses in its
-        address to device map, determines that in this case the address
-	belongs to the phb and passes it down.
-
-   3.	The <<phb>> in turn determines that the address belongs to the
-   	serial port and passes to that device the request for an access
-	to location <<0x3f8>>.

-   /pci/isa8086/fdc@300    # floppy disk controller on ISA bus
-
-   A processor needing to access the device fdc@300 on the ISA bus
-   would do so using a data path that goes through the pci-host bridge
-   (pci)and the isa-pci bridge (isa8086) to finally reach the device
-   fdc@300.  As the data transfer passes through each intermediate

-   device.  Both multiple destinations attached to a single source and

-   occures.  Each of those destination (device/port) are able to
-   further propogate the interrupt until it reaches its ultimate
-   destination.
-
-   Normally an interrupt source would be a model of a real device
-   (such as a keyboard) while an interrupt destination would be an
-   interrupt controller.  The facility that allows an interrupt to be
-   delivered to multiple devices and to be propogated from device to
-   device was designed to support the requirements specified by

-
-		o	(Re)attach its own addresses to its parent device.
-
-		o	Ensure that it is otherwize sufficiently

-        5.      All properties containing an instance of
-                a device are (re)initialized

-/* where FMT,... once formatted (using vsprintf) is used to locate and
-   create either a device or property.  Its syntax is almost identical
-   to that used in OpenBoot documentation - the only extension is in
-   allowing properties and their values to be specified vis:
-
-   "/pci/pci1000,1@1/disk@0,0"
-
-   Path:
-
-   The path to a device or property can either be absolute (leading
-   `/') or relative (leading `.' or `..').  Relative paths start from
-   the CURRENT node.  The new current node is returned as the result.
-   In addition, a path may start with a leading alias (resolved by
-   looking in /aliases).
-
-   Device name:
-
-   <name> "@" <unit> [ ":" <args> ]
-
-   Where <name> is the name of the template device, <unit> is a
-   textual specification of the devices unit address (that is
-   converted into a numeric form by the devices parent) and <args> are
-   optional additional information to be passed to the device-template
-   when it creates the device.
-
-   Properties:
-
-   Properties are specified in a similar way to devices except that
-   the last element on the path (which would have been the device) is
-   the property name. This path is then followed by the property
-   value. Unlike OpenBoot, the property values in the device tree are
-   strongly typed.
-
-   String property:
-
-     <property-name> " " <text>
-     <property-name> " " "\"" <text>
-   
-   Boolean property:
-
-     <property-name> " " [ "true" | "false" ]
-   Integer property or integer array property:
-
-     <property-name> " " <number> { <number> }
-
-   Phandle property:
-
-     <property-name> " " "&" <path-to-device>
-
-   Ihandle property:
-
-     <property-name> " " "*" <path-to-device-to-open>
-
-   Duplicate existing property:
-
-     <property-name> " " "!" <path-to-original-property>
-
-
-   In addition to properties, the wiring of interrupts can be
-   specified:
-
-   Attach interrupt <line> of <device> to <controller>:
-
-     <device> " " ">" <my-port>  <dest-port> <dest-device>
-
-
-   Once created, a device tree can be traversed in various orders: */
