// 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.
