3398 + * Started revision history
3399 + * Made IDT_BUS_FREQ a kernel configuration parameter
3400 + ****************************************************************************
3401 + * P. Sadik Oct 10, 2003
3402 + *
3403 + * Removed IDT_BUS_FREQ, since this parameter is no longer required. Instead
3404 + * idt_cpu_freq is used everywhere
3405 + ****************************************************************************
3406 + * P. Sadik Oct 20, 2003
3407 + *
3408 + * Removed RC32434_BASE_BAUD
