[PATCH] microblaze: Cleanup linker script using new linker script macros.

From: Tim Abbott
Date: Sun Sep 06 2009 - 23:10:38 EST


I wasn't able to further clean up the linker script using the
INIT_DATA_SECTION macro because of the FIXME comment for the
.init.ramfs section; when that is resolved we should convert
microblaze to use INIT_DATA_SECTION.
