This patch configures the user LED on Snowball to double flash every second or so, whilst it's still alive. This can give key indications as to what the board is doing in the case of no console output. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
