The EFI_RNG_PROTOCOL is needed for Linux' KASLR.

QEMU can provide a virtio-rng device to emulate a hardware random number
generator which is supported by our virtio_rng driver.

Enabling CONFIG_DM_RNG will enable CONFIG_VIRTIO_RNG and
CONFIG_EFI_RNG_PROTOCOL by default too.

Hi Heinrich,

This patch seems to cause CI: test/py/tests/test_efi_selftest.py to fail.
(https://source.denx.de/u-boot/custodians/u-boot-riscv/-/jobs/666642)
Could you take a look at this and check if anything else needs modification?

Best regards,
Leo

Hello Leo,

thanks for sharing the test result.

u-boot-test-hooks does not enable device virtio-rng-pci on RISC-V. I 
will adjust this.

Best regards

Heinrich
