Subject[PATCH] mn10300 linker script cleanup
David,

I noticed that you already converted to mn10300 architecture to use some
of the new macros in vmlinux.lds.h. It seems to me that one could clean
things up further by using some of the higher-level macros
(RW_DATA_SECTION, INIT_TEXT_SECTION, INIT_DATA_SECTION). Patch below.

Best regards,
-Tim Abbott
