At present get_timer() does not return sane values. It should count up smoothly in milliscond intervals. We can change the PWM to count down at 1MHz, providing a resolution of 1us and a range of about an hour between required get_timer() calls. Test with command "sf probe 1:0; time sf read 40008000 0 1000". Try with different numbers of bytes and see that sane values are obtained Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Akshay Saraswat <akshay.s@samsung.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com> |
