4 | * This is basically a copy of include/asm-i386/serial.h. | |
5 | * It is used on platforms which have an ISA bus and thus are likely | |
6 | * to have PC-style serial ports at the legacy I/O port addresses. | |
7 | * It also includes the definitions for the fourport, accent, boca | |
8 | * and hub6 multiport serial cards, although I have never heard of | |
9 | * anyone using any of those on a PPC platform. -- paulus | |

14 | * This assumes you have a 1.8432 MHz clock for your UART. | |
15 | * | |
16 | * It'd be nice if someone built a serial card with a 24.576 MHz | |
17 | * clock, since the 16550A is capable of handling a top speed of 1.5 | |
18 | * megabits/second; but this requires the faster clock. | |
