 * All this is intended to be used with a 16550-like UART on the PCMCIA bus.
 * It has nothing to do with the SA1100's internal serial ports.
 * This is included by serial.c -- serial_s3c2410.c makes no use of it.

 * This assumes you have a 1.8432 MHz clock for your UART.
 *
 * It'd be nice if someone built a serial card with a 24.576 MHz
 * clock, since the 16550A is capable of handling a top speed of 1.5
 * megabits/second; but this requires the faster clock.
