I get some warnings from arch/arm/cpu/armv7/omap4/emif.c:
emif.c: In function ?sdram_init?:
emif.c:1164:43: warning: ?section_map? may be used uninitialized in
this function
emif.c:1166:27: warning: ?lis_map_regs_calculated$dmm_lisa_map_3? may
be used uninitialized in this function
emif.c: In function ?sdram_init?:
emif.c:1166:27: warning: ?lis_map_regs_calculated$dmm_lisa_map_3? may
be used uninitialized in this function

Looking at the code I see that these are initialized but the compiler
can't firgure that out.
