Linux/AM3359: crng init done is slow

Part Number: AM3359

Tool/software: Linux

Hello,

I have a Linux question regarding random.

Currently I'm getting the # [  101.922605] random: crng init done in about 80-120 seconds. My platform boots in about 5 seconds but the random crng init done message arrives many seconds after that. The issue is that I have a web server running which seems to be stuck until crng init done appears.

Is there a way to make crng initialize faster? Does it need any hw support that I could add in linux menuconfig when building the kernel? I'm using buildroot to make the kernel so I can customize it.

Many thanks in advance!
