Subject: [PATCH v2 0/3] powerpc: wire up rng during setup_arch
Date: Sat, 11 Jun 2022 12:04:44 +0200 [thread overview]
Message-ID: <20220611100447.5066-1-Jason@zx2c4.com> (raw)
The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call. This series
wires that up properly on the three platforms that currently initialize
the RNG from the wrong place.
