Module Name:

    pxmapio.c

Abstract:

    This module implements the mapping of HAL I/O space for a POWER PC
    system.

Author:

    David N. Cutler (davec) 28-Apr-1991

Environment:

    Kernel mode

Revision History:

    Jim Wooldridge (jimw@austin.vnet.ibm.com) Initial PowerPC port

       Map interrupt acknowledge base address
       Map SIO config base address
       Remove RTC map - S-FOOT mapsthe RTC into the ISA I/O space

Routine Description:

    This routine maps the HAL I/O, planar control, and bus configuration
    spaces for a PowerPC system.

Arguments:

    None.

Return Value:

    If the initialization is successfully completed, than a value of TRUE
    is returned. Otherwise, a value of FALSE is returned.
