From c3e2586b794b12ffcdf69b4e547030b51e18e6d9 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Sat, 9 May 2009 23:33:02 +0900
Subject: sh: Integrate sh64 bits in vmlinux_32.lds.S.

This adds all of the requisite bits from vmlinux_64.lds.S in to the _32
variant, resulting in a unified and generic linker script that can be
shared across both.
