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.

involved with the initializations, esp. if it's noted why the

0x3c0 -> 0x3cf, and 0x3d0 -> 0x3df. The former chunk has to be split

the GENERIC kernels.
