+ * NS16550 Serial Port
+ * originally from linux source (arch/ppc/boot/ns16550.h)
+ * modified slightly to
+ * have addresses as offsets from CFG_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 8245 duart
