In order to use high resolution timers, an ARMv7 system needs an
additional clocksource that is not the arch timer.
The other option is to set the always-on property in the arch timer.
This has been discouraged in the past[1].
I propose we enable the aspeed timer in the openbmc tree, and work out
how to proceed longer term upstream. I've submitted the timer changes
upstream as we can have driver support regardless as to weather we use
it.
