 * ld script to make ST50 Linux kernel
 *
 * Copyright (C) 2000, 2001  Paolo Alberelli
 *
 * benedict.gaster@superh.com:	 2nd May 2002
 *    Add definition of empty_zero_page to be the first page of kernel image.
 *
 * benedict.gaster@superh.com:	 3rd May 2002
 *    Added support for ramdisk, removing statically linked romfs at the same time.
 *
 * lethal@linux-sh.org:          9th May 2003
 *    Kill off GLOBAL_NAME() usage and other CDC-isms.
 *
 * lethal@linux-sh.org:         19th May 2003
 *    Remove support for ancient toolchains.
