Generally, on L4, device drivers are normal programs, i.e. you can use
whatever environment you like (i.e. that is available). Device access is
typically through MMIO, i.e. memory accesses, which can just be
accessed, after being configured and allowed in IO for that client.
Maybe you could be more specific on your plans.
