- * BRIEF MODULE DESCRIPTION

- * The general-purpose functions to read/write and configure the GT64120A's

- * copies of functions written by Galileo Technology, or are modifications
- * of their functions to work with Linux 2.4 vs Linux 2.2.  These functions
- * are Copyright - Galileo Technology.
- *
- * Other functions are derived from other MIPS PCI implementations, or were
- * written by RidgeRun, Inc,  Copyright (C) 2000 RidgeRun, Inc.
