-* 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.
