+ Normally this driver is controlled by the following options:
+
+ CONFIG_SYS_NS16550_PORT_MAPPED - indicates that port I/O is used for
+ access. If not enabled, then the UART is memory-mapped.
+ CONFIG_SYS_NS16550_MEM32 - if memory-mapped, indicates that 32-bit

+ endianness. If positive, big-endian access is used. If negative,
+ little-endian is used.
+
+ It is not a good practice for a driver to be statically configured,
+ since it prevents the same driver being used for different types of
