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.
