	  Platform Runtime Mechanism (PRM) is a firmware interface exposing a

	  set of binary executables that can be called from the AML interpreter

	  or directly from device drivers.



	  Say Y to enable the AML interpreter to execute the PRM code.



	  While this feature is optional in principle, leaving it out may

	  substantially increase computational overhead related to the

	  initialization of some server systems.
