Subject: [PATCH] [nrf noup] entropy: Add fake entropy nRF PRNG driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This adds temporary entropy driver simulation for
nRF54l09 device since final entropy source is not
available yet.

TODO: Remove this commit when proper solution will
be available.
