    [RAPIDIO] Add RapidIO multi mport support · ad1e9380
    Zhang Wei authored
    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.
