// N.B. This file will define the 'default' Alpha configuration for
// the I8042 port driver. It assumes the register definitions from the
// VLSI Technology 82c106 chip. If any of these definitions must change,
// then some other (special) action must also happen - like building a
// separate binary driver for the specific Alpha platform.
//
// On Alpha systems, the normal behavior is to get the real configuration
// information from the (ARC compliant) firmware.

//
// Define the interrupt-related configuration constants.
