	The standalone example does not have get_timer() defined, so we cannot rely on it being available. Move the timer function into boootstage.c to avoid this problem. This corrects a build breakage for the standalone example on some boards. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Matthias Fuchs <matthias.fuchs@esd.eu>
