-/*
- * NS16550 Serial Port
- * originally from linux source (arch/powerpc/boot/ns16550.h)
- * modified slightly to
- * have addresses as offsets from CONFIG_SYS_ISA_BASE
- * added a few more definitions
- * added prototypes for ns16550.c
- * reduced no of com ports to 2
- * modifications (c) Rob Taylor, Flying Pig Systems. 2000.
- *
- * further modified to support the DUART in the Galileo eval board
- * modifications (c) Josh Huber <huber@mclx.com>, Mission Critical Linux, Inc.
