Module Name:

    simbus.c

Abstract:

    This module implements the routines to support the management
    of bus resources and translation of bus addresses.

/*++

Routine Description:

    This function stores the value of argument BusAddress into the
    memory location referenced by argument TranslatedAddress.  The
    argument referenced by AddressSpace is always set to 0 because
    there is no I/O port space in IA64 architecture.

    In the simulation environment, this function may be called by
    the video miniport driver only to determine the frame buffer
    physical address.

Return Value:

    Returns TRUE.

/*++

Routine Description:

    Flushes all write buffers and/or other data storing or reordering
    hardware on the current processor.  This ensures that all previous
    writes will occur before any new reads or writes are completed.

    In the simulation environment, there is no write buffer and nothing
    needs to be done.

Arguments:

    None

Return Value:

    None.
