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
