[ 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.
