As a device-driver developer, I want vemu to model BCM system timer, so that I can build and test firmware that needs linux clocksource/clockevent on all Pi generations long before the hardware is in hand.

Why it matters

Linux clocksource/clockevent on all Pi generations

Summary

Free-running 1 MHz counter + 4 compare registers with IRQs

Scope of work

Not present today. Deliver a behavioral model of BCM system timer. What it is: Free-running 1 MHz counter + 4 compare registers with IRQs. Why it matters: Linux clocksource/clockevent on all Pi generations.
