Thomas Petazzoni bf9c7e3d79 arch/sh: pcie-sh7786: handle non-zero DMA offset ... On SuperH, the base of the physical memory might be different from zero. In this case, PCI address zero will map to a non-zero physical address. In order to make sure that the DMA mapping API takes care of this DMA offset, we must fill in the dev->dma_pfn_offset field for PCI devices. This gets done in the pcibios_bus_add_device() hook, called for each new PCI device detected. The dma_pfn_offset global variable is re-calculated for every PCI controller available on the platform, but that's not an issue because its value will each time be exactly the same, as it only depends on the memory start address and memory size.
