[PATCH 0/1] This patch adds support for the entropy generator present in

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.

Max Resch (1): add turris-rwtm-rng from CZ.NIC rWTM Firmware
