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

mn10300: Clean up linker script using higher-level macros.
