+* 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
+**********************************************************************
+
+  P.Christeas, 2005-2006
+  Port to 2.6, add 2.6 cmdline parsing
