- * All this is intended to be used with a 16550-like UART on the SA1100's
- * PCMCIA bus. It has nothing to do with the SA1100's internal serial ports.
- * This is included by serial.c -- serial_sa1100.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.
