* ld script to make SH64 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.
