rapidio: add RapidIO channelized messaging driver
Add channelized messaging driver to support native RapidIO messaging exchange between multiple senders/recipients on devices that use kernel RapidIO subsystem services. This device driver is the result of collaboration within the RapidIO.org Software Task Group (STG) between Texas Instruments, Prodrive Technologies, Nokia Networks, BAE and IDT. Additional input was received from other members of RapidIO.org. The objective was to create a character mode driver interface which exposes messaging capabilities of RapidIO endpoint devices (mports) directly to applications, in a manner that allows the numerous and varied RapidIO implementations to interoperate. This char mode device driver allows user-space applications to setup messaging communication channels using single shared RapidIO messaging mailbox. By default this driver uses RapidIO MBOX_1 (MBOX_0 is reserved for use by RIONET Ethernet emulation driver).
