The original RapidIO driver suppose there is only one mpc85xx RIO controller in system. So, some data structures are defined as mpc85xx_rio global, such as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's private members. And you can define multi RIO OF-nodes in dts file for multi RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in Freescale's silicon. And the mport operation function declaration should be changed to know which RapidIO controller is target. Thanks!
