+Subject: [PATCH] hwrng: omap - Set default quality
+
+Newer combinations of the glibc, kernel and openssh can result in long initial
+startup times on OMAP devices:
+
+[    6.671425] systemd-rc-once[102]: Creating ED25519 key; this may take some time ...
+[  142.652491] systemd-rc-once[102]: Creating ED25519 key; done.
+
+due to the blocking getrandom(2) system call:
+
+[  142.610335] random: crng init done
+
+Set the quality level for the omap hwrng driver allowing the kernel to use the
+hwrng as an entropy source at boot.
+
