| Subject: 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. |
