From a0f19a894c46e5ceb7334d4d66453e566152ed1e Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Sat, 14 Sep 2019 14:02:57 -0700 Subject: hwrng: omap3-rom - Initialize default quality to get data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Similar to commit 62f95ae805fa ("hwrng: omap - Set default quality") we need to initialize the default quality for the RNG to be used. The symptoms of this problem is that doing hd /dev/random does not produce much data at all.
