Log Message:
Import code from FreeBSD to tell the controller how much physical RAM the
system has.  This has the (scary-because-we've-been-running-so-long-
without-it) commit message (for the first version of the change):
        Tell the controller how much physical memory we have.  Without this
        there was a chance that our DMA regions would collide with the
        memory window used by the cache on the controller.  The result would
        be massive data corruption.  This seemed to mainly affect systems with
        >2GB of memory.
