Dear Maintainer,

While testing Debian 10 on a Marvell 8040 SoC I found that the rng and SSH were
coming up extremely slow, taking over a minute to start.

This is caused by somebody disabling the rng driver for arm64 kernels a long time ago:
linux (4.14.13-1) unstable; urgency=medium
...
  [ Riku Voipio ]
  * [arm64] disable CONFIG_HW_RANDOM_OMAP until the IRQ storm bug is fixed

What is this IRQ storm bug? Has it been fixed? Can we re-enable this driver?

Yours sincerely
Josua Mayer
