*
* Miles Bader <miles@gnu.org> added NEC V850E support.
* very minor changes required to also work with StrongArm and presumably
* all ARM based systems.
*
+ * Paul Mundt <lethal@linux-sh.org> 08-Aug-2003.
+ * Integrated support for sh64 (SH-5), from preliminary modutils
+ * patches from Benedict Gaster <benedict.gaster@superh.com>.
+ * Currently limited to support for 32bit ABI.
+ *
* Magnus Damm <damm@opensource.se> 22-May-2002.
* The plt and got code are now using the same structs.
* Added generic linked list code to fully support PowerPC.
