Seems to make sense, but shouldn't the patch title be "Use
engine->mmio_base as predicate for mock engine hw access"?
But we use b->irq_enable for the important bit.
You mean in irq_enable/disable helpers? But that's the same before and
after the patch. The change seems to be dropping of selftests specific
variable in favour of engine->mmio_base. Am I blind again?
