/*
 * CIA is the internal name for the 21171 chipset which provides
 * memory controller and PCI access for the 21164 chip based systems.
 * Also supported here is the 21172 (CIA-2) and 21174 (PYXIS).
 *
 * The lineage is a bit confused, since the 21174 was reportedly started
 * from the 21171 Pass 1 mask, and so is missing bug fixes that appear
 * in 21171 Pass 2 and 21172, but it also contains additional features.
 *
 * This file is based on:
 *
 * DECchip 21171 Core Logic Chipset
 * Technical Reference Manual
