The kzm9g board fails in building with -march=armv7-a. This fixs this problem by converting to do_div(). ----- USE_PRIVATE_LIBGCC=yes ./MAKEALL kzm9g ... arch/arm/cpu/armv7/rmobile/librmobile.o: In function `get_time_us': arch/arm/cpu/armv7/rmobile/timer.c:41: undefined reference to `__aeabi_uldivmod' arch/arm/cpu/armv7/rmobile/librmobile.o: In function `get_time_ms': arch/arm/cpu/armv7/rmobile/timer.c:47: undefined reference to `__aeabi_uldivmod' ----- Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> CC: Tetsuyuki Kobayashi <koba@kmckk.co.jp>
