Structure Description:

    This structure describes the RealView ACPI table.

Members:

    Header - Stores the standard ACPI table header. The signature here is
        'WVLR'.

    Pl110PhysicalAddress - Stores the phyiscal address of the PL110 LCD
        controller.

    TimerPhysicalAddress - Stores the physical addressES of the timer blocks.

    TimerFrequency - Stores the frequencies of the timers, or zero for
        unknown.

    TimerGsi - Stores the Global System Interrupt numbers of the timers.

    DebugUartPhysicalAddress - Stores the physical address of the UART used for
        serial debugging.

    DebugUartClockFrequency - Stores the frequency of the clock use for the
        UART.
