This patch set defines a binding for FSL MPIC message registers and implements an API for accessing those message registers. Testing was done on a MPC8572DS in an Linux-Linux AMP setup using OpenMCAPI (www.openmcapi.org) to communicate between OS instances. The message register API is used by the OpenMCAPI shared memory driver to send notifications between cores.
