powerpc: add support for MPIC message register API 2012-03-16T21:15:28+00:00 Jia Hongtao B38951@freescale.com 2012-02-17T02:49:03+00:00 8626816e905e8e131663dfcae27d307df8c220d0 Some MPIC implementations contain one or more blocks of message registers that are used to send messages between cores via IPIs. A simple API has been added to access (get/put, read, write, etc ...) these message registers. The available message registers are initially discovered via nodes in the device tree. A separate commit contains a binding for the message register nodes.
