	Timer on cyclone5 actually counts down. It took me a while to figure out, as timer counting in wrong direction actually _can_ be used, it just appears to tick at extremely high frequency in u-boot. The bug was introduced in commit 23ab7ee0ffa9d5efd0b4ad830befba306d24a327. Signed-off-by: Pavel Machek <pavel@denx.de> Acked-by: Marek Vasut <marex@denx.de>
