This patch enables the hardware random number generator in the device tree.
Without it, the entropy level in the Linux kernel increases very slowly.
To check the entropy level: cat /proc/sys/kernel/random/entropy_avail

Hi, Baruch
For some reason, the email from you turned out to be empty, so I 
inserted the text from patchwork in the response.

Without this comment, the verification script (utils/docker-run make 
check-package) reports an error. I took this comment from some similar 
buildroot patch.
