For hw_random Kernel Support you need to enable :
CONFIG_HW_RANDOM=m
CONFIG_HW_RANDOM_TIMERIOMEM=m
CONFIG_HW_RANDOM_INTEL=m
CONFIG_HW_RANDOM_AMD=m
CONFIG_HW_RANDOM_GEODE=m
CONFIG_HW_RANDOM_VIA=m
CONFIG_HW_RANDOM_VIRTIO=m
CONFIG_HW_RANDOM_TPM=m
Hardware randomization support can be enabled by loading one of the following kernel modules:
modprobe virtio-rng
modprobe intel-rng
modprobe and-rng
modprobe tpm-rng
modprobe via-rng
modprobe timeriomem-rng
(& add the module to /etc/modules)
All 3 applications exist as packages in Alpine Linux which also has kernel support for hw_random
