This patch adds reset_timer() before the flash status check waiting loop. Since the timer is basically running asynchronous to the cfi code, it is possible to call get_timer(0), then only a few _SYSCLK_ cycles later an interrupt is generated. This causes timeout even though much less time has elapsed. So the timer period registers should be reset before get_timer(0) is called. There is similar usage in nand_base.c. Signed-off-by:
