enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.
to both the EEPROM *and* the PHY on the Ethernet interface now, at least,
though it is still not completely working.
Many thanks to Stephen Goadhouse at ADI for some hints.
indirect configuration (because the BECC is a soft-core, it could
have a variety of peripherals in the FPGA). Also add support for
local untranslated DMA.
