It doesn't seem to:
warthog>grep -r mcpu arch/m68k warthog1>grep -r mtune arch/m68k warthog1>
I see that m68knommu does:
warthog1>grep -r mcpu arch/m68knommu/ arch/m68knommu/Makefile:cflags-$(CONFIG_M5206) := $(call cc-option,-mcpu=5206,-m5200) arch/m68knommu/Makefile:cflags-$(CONFIG_M520x) := $(call cc-option,-mcpu=5208,-m5200) arch/m68knommu/Makefile:cflags-$(CONFIG_M523x) := $(call cc-option,-mcpu=523x,-m5307) ...
I guess the m68k compiler I already had doesn't fully support -m5200, since I see that, but it doesn't compile some of the instructions when compiling the m68knommu defconfig (CONFIG_M520x=y).
