Due to the fact that AMD Seattle maps all its DRAM starting at physical address 0x80_0000_0000, we currently only support DMA for devices that can access 40 bits of physical address space.
This is not a problem for the onboard devices, but it would be useful if we could support random PCIe plug-in cards, even if they are only 32-bit DMA capable.
Fortunately, there is a ARM (tm) Corelink(r) MMU-401 between the PCIe root complex and the CPU bus, and so all we need to do is to inform the OS about this. So add a description of it to the APCI IORT table.
While we're at it, let's describe all the other SMMUs we may be able to make use of, i.e., 2x SATA and 2x XGBE, as well.
