Subject: non-CFI flash code uses data from CFI structures. Make sure that timeouts are filled... 
X-Git-Tag: v0.5.0-rc1~234
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=d8ece229f9f06e66ad994ca996148912dc0b76b5;p=openocd

non-CFI flash code uses data from CFI structures. Make sure that timeouts are filled in on non-CFI flashes, and print CFI information in all cases, nut just on CFI flashes.
