/*
 * For now: we hard coded the DMA configurations.
 *          and assume for one partition only.
 *
 *       OBP. Then OBP will pass this partition's
 *       Neptune configurations to fcode to create
 *       properties for them.
 *
 *      Since Neptune(PCI-E) and NIU (Niagara-2) has
 *      different bus interfaces, the driver needs
 *      to know which bus it is connected to.
 *      Ravinder suggested: create a device property.
 *      In partitioning environment, we cannot
 *      use .conf file (need to check). If conf changes,
 *      need to reboot the system.
 *      The following function assumes that we will
 *      retrieve its properties from a virtualized nexus driver.
