/*
* 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
*
* EC-QE18B-TE
*
* david.rusling@reo.mts.dec.com Initial Version.
