[U-Boot] U-Boot uptime

[Andrew Wozniak]

Hi everyone,

It has a quite a while since my last post here. Our new project is running
U-Boot on a custom Beaglebone board. While running several overnight
user-space applications, the board reset and stopped at the U-Boot prompt.
We do not yet have any logging but I could monitor and record the console
output to see when this reset happened.

A simpler approach could employ an "uptime" clock at the U-Boot level. Does
U-Boot have such a timer?
