+ * NS16550 Serial Port
+ * originally from linux source (arch/powerpc/boot/ns16550.h)
+ *
+ * Cleanup and unification
+ * (C) 2009 by Detlev Zundel, DENX Software Engineering GmbH
+ *
+ * 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.
+ *
+ * added support for port on 64-bit bus
+ * by Richard Danter (richard.danter@windriver.com), (C) 2005 Wind River Systems
