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