    Add support for the Artesyn MVME7100 Single Board Computer.
    
    The MVME7100 is a 6U form factor VME64 computer with:
    
        - A two e600 cores Freescale MPC8641D CPU
        - 2 GB of DDR2 onboard memory
        - Four Gigabit Ethernets
        - Five 16550 compatible UARTs
        - One USB 2.0 port
        - Two PCI/PCI eXpress Mezzanine Card (PMC/XMC) Slots
        - A DS1375 Real Time Clock (RTC)
        - 512 KB of Non-Volatile Memory (NVRAM)
        - Two 64 KB EEPROMs
        - 128 MB NOR and 4/8 GB NAND Flash
    
    This patch is based on linux-4.7-rc1 and has been only boot tested.
    
    Limitations:
        This patch covers only models 171 and 173
        No plans to support CPLD timers
    
    Know issues:
        All four PHYs work in polling mode
    
    Configuration is missing for:
        PCI IDSEL and PCI Interrupt definition
    
    Support is missing for:
        Cache and memory controllers (which are very similar to the 85xx ones
            but right now I don't know if we can re-use their support)
        Watchdog, USB, NVRAM, NOR, NAND, EEPROMs, VME, PMC/XMC and RTC
