I'm quite sure that on the Midway platform get_timer was returning ms and the 5s grub countdown took 5s after my fix and some interminably long time before it. Sadly actual documentation of the u-boot API is a bit thin on the ground, but get_timer==ms is also corroborated by some ad-hoc googling I did (e.g. resulting in the above link) as well as inspection of some random u-boot ports. Some ports have an explicit get_timer_us function, which adds credence to the idea that get_timer is in ms instead.
