Previously "reading" clock info (and part info) also, as a side effect, wrote the flash timing register. Instead, be more safe: "reading" should only read. Write paths still refresh timing, coping with changes the application code may have made. Also rename the routine which sets flash timing, indicating what it's really doing; it's got nothing to do with a "mode". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
