Add debugging support to the bus_space macros. If BUS_SPACE_DEBUG (or DEBUG)
...
is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used. If they are not, a message will be displayed on
the console.
Strict alignment is required by the Alpha architecture, and a trap will
occur of unaligned access is performed. These changes will aid debugging
of broken device drivers.

Deal with a hardware bug in Pass 1 and Pass 2 Pyxis chips. Basically,
...
the scatter/gather TLB cannot be invalidated on these chips. So, to
work around this, we configure the otherwise unsed DMA Window 2 as a
2M SGMAP window at 128M, point all of its page table entries at the
DMA spill page, and, when the TLB is to be invalidated, put the PCI bus
into loopback mode, and create a target hit on Window 2 every 64k for
the number of TLB entries (plus a few ... it seems to not work unless
we read a few extra times), forcing out old TLB entries to make room for
the new, dummy target hits.
