Subject: [PATCH 00/12] bcm63xx-rng conversion to bcm2835-rng
Date: Wed, 1 Nov 2017 18:03:56 -0700 [thread overview]
Message-ID: <20171102010408.27736-1-f.fainelli@gmail.com> (raw)
Hi,
As it usually happens when there is a fair amount of HW IP block re-use,
competing implementations show up. In that case the BCM2835 HWRNG driver and
the BCM63xx RNG driver have exactly the same register offsets and this is
indeed the same piece of HW.
This patch series first prepares the bcm2835-rng to be more future proof and
support newer platforms, and the last part brings in what is necessary to
migrate the bcm63xx-rng over to bcm2835-rng. Finally we delete bcm63xx-rng
completely.
The reason why BCM2835 RNG was kept over BCM63xx RNG is because the former
deals correctly with a warm up count and the number of words available in the
FIFO size.
Thanks!
