FS#1951 - brcm63xx: Livebox: 4.14 kernel boot stuck at "random: crng init done"

[openwrt-bot]

danitool:

The kernel 4.14 is unable to boot on the Inventel Livebox 1 (BCM6348 board with a redboot bootloader).

Steps to reproduce:

• Intall the latest trunk version (i.e. r8455-042d68a) kernel 4.14

Sympthoms:

• It won't detect the BogoMips CPU speed
• It stucks at "random: fast init done", and apparently no more kernel messages
• But after a minute it spits the last message random: crng init done

Boot log:

The same problem into brcm63xx: Hg556a can't use the latest version for the same reason
