/*
* prom.c
**********************************************************************
* P . Sadik Oct 10, 2003
*
* Started change log
* idt_cpu_freq is make a kernel configuration parameter
* idt_cpu_freq is exported so that other modules can use it.
* Code cleanup
**********************************************************************
* P. Sadik Oct 20, 2003
*
* Removed NVRAM code from here, since they are already available under
* nvram directory.
* Added serial port initialisation.
**********************************************************************
**********************************************************************
* P. Sadik Oct 30, 2003
*
* Added reset_cons_port
**********************************************************************
