sys/arch/sgi/xbow: xbridge.c xbridgereg.h
Log message:
Provide more xbridge-specific functions in the bus_dma_tag_t we use for
PCI buses on xbridge.
In addition to this, we now support the limited IOMMU, allowing memory
outside of the 2GB direct window to be used for DMA.
Only tested on XBridge chip so far; this lets an IP35 machine with
physical memory after the 2GB boundary run stable again.
