the Armada3700 Secure Processor. This rng is onlt accessible to the rWTM firmware. Currently the CZ.NIC Turris Mox firmware exposes this.
For the Linux kernel a driver called turris-mox-rwtm exists that makes use of this feature. This RNG driver for U-Boot tries to do the same. For efficiency I chose to cache 4k of enthropy in a ringbuffer.
