Re: [U-Boot] [PATCH 03/18] dm: timer: handle being called before dm_root is ready

When used with bootstage recording, dm_timer_init may be called surprisingly early: i.e. before dm_root is ready. To deal with this case, we explicitly check for this condition and return -EAGAIN to the caller (refer to drivers/timer/rockchip_timer.c for a case where this is needed/used).

We should be using the early timer in this situation but I suppose this is useful for boards that don't have one.
