hwrng: omap - Set default quality
[ Upstream commit 62f95ae805fa9e1e84d47d3219adddd97b2654b7 ]
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.
