| H A D | cfi_flash.c | 22d6c8faac4e9fa43232b0cf4da427ec14d72ad3 Thu Apr 01 03:15:05 UTC 2010 Thomas Chou <thomas@wytron.com.tw> cfi_flash: reset timer in flash status check
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.
