- * benedict.gaster@superh.com: 2nd May 2002
- * Modified to use the empty_zero_page to pass command line arguments.
- *
- * benedict.gaster@superh.com: 3rd May 2002
- * Added support for ramdisk, removing statically linked romfs at the same time.
- *
- * lethal@linux-sh.org: 15th May 2003
- * Added generic procfs cpuinfo reporting. Make boards just export their name.
- *
- * lethal@linux-sh.org: 25th May 2003
- * Added generic get_cpu_subtype() for subtype reporting from cpu_data->type.
