12      * CIA is the internal name for the 21171 chipset which provides
13      * memory controller and PCI access for the 21164 chip based systems.
14      * Also supported here is the 21172 (CIA-2) and 21174 (PYXIS).
15      *
16      * The lineage is a bit confused, since the 21174 was reportedly started
17      * from the 21171 Pass 1 mask, and so is missing bug fixes that appear
18      * in 21171 Pass 2 and 21172, but it also contains additional features.
