H A D | powernv-rng.c | 66548e40 Thu Oct 10 22:07:58 CDT 2013 Michael Ellerman <michael@ellerman.id.au> hwrng: Add a driver for the hwrng found in power7+ systems
Add a driver for the hwrng found in power7+ systems, based on the existing code for the arch_get_random_long() hook.
We only register a single instance of the driver, not one per device, because we use the existing per_cpu array of devices in the arch code. This means we always read from the "closest" device, avoiding inter-chip memory traffic.
