io_bus is split out into pio_bus and dma_bus so that any device
can specify either independently. python/m5/objects/Device.py: io_bus is split out into pio_bus and dma_bus so that any device can specify either independently. dma_bus defaults to point to whatever pio_bus uses. --HG-- extra : convert_revision : d35d5374d0bf592f6b5df465c05203577b8b8763
