Subject: [PATCH 0/1] This patch adds support for the entropy generator present in
Date: Sat, 20 Jan 2024 14:27:22 +0100 [thread overview]
Message-ID: <20240120132731.35321-1-resch.max@gmail.com> (raw)
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.
