[PATCH 0/2] powerpc: define and implement MPIC message register support

[Meador Inge]

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.
