+* @details
+* enumerator and driver interface to ODP
+*
+*  1) ODP loads the different modules (i.e. it loads shared libraries, *.so).
+*     In the context of drivers, shared libraries may contain enumerators,
+*     drivers and devios. These register in step 2.
+*
+*  2)  odpdrv_enumr_class_register(int (probe*)()...)
+*      ----------------------------------------------------------->
+*      odpdrv_driver_register(int (probe*)()...)
+*      ----------------------------------------------------------->
+*      odpdrv_devio_register()
+*      ----------------------------------------------------------->
+*  A number of device_enumerator_classes are registered at the ODP startup.
+*  Many classes are expected: static, ACPI, PCI, switchdev, virtual, DPAA2...
+*  A number of drivers also register to ODP (passing their own probe function).
+*  A number of device IO may also register to ODP (defining available devices
+*  interfaces).
+*
+*  3)  ODP calls the probe function of each enumerator class
+*      <-----------------------------------------------------------
+*      odpdrv_emum_register(int (probe*)()...)
+*      ----------------------------------------------------------->
+*      ----------------------------------------------------------->
+*      ----------------------------------------------------------->
+*      odpdrv_devio_register(...)
+*      ----------------------------------------------------------->
+*      ----------------------------------------------------------->
+*      ----------------------------------------------------------->
+*  ODP calls the probe function of each registered enumerator_class.
+*  This result in the enumerator_class registering some
+*  enumerators (instances of the class) by calling
+*  odpdrv_emumerator_register() for each instance.
+*  A given enumerator_class may create many enumerators based on its platform:
+*  For instance Linux defines a number of PCI domains that can be viewed as
+*  multiple PCI enumerators. In addition, it could be considered that each PCI
+*  root of each processor socket in a NUMA environment has its own PCI
+*  enumerator.
+*  For enumerator class PCI, there could be one instance for each PCI
+*  domain.
+*  Note that the probe function of a given class may be recalled at any time
+*  (Hotplug)
+*  The devios delivered with their enumerator may also register at this stage.
+*
+*  4) For each enumerator instance, odp calls the probe function to retrieve
+*  the list of devices enumerated by the given enumerator instance.
+*  Note that the probe function of a given enumerator may be recalled at any
+*  time(Hotplug)
+*
+*  5) The driver framework calls the drivers probe(D,I) functions of the
+*  drivers, with device D and devio I as parameter, assuming that:
+*	-devio I was on the driver supported list of devio (and version matches)
+*	-the devio I is registered and found its enumerator interface(E) api
+*	 (name and version)
+*	-device D was enumerated by an enumerator providing interface E.
+*  The return value of the driver probe function tells whether the driver
+*  can handle the device or not.
