powerpc/xmon: Add option to show uptime information
It might be useful to quickly get the uptime of a running system on
xmon, without needing to grab data from memory and doing math on
struct addresses.
For example, it'd be useful to check for how long after a crash a
system is on xmon shell or if some test was started after the first
test crashed (and this 2nd test crashed too into xmon).
This small patch adds the 'U' command, to accomplish this.
