Review Comment:
Because cryptographic entropy is a core security requirement rather than an
optional feature.
The JZ4780 RNG is an integrated on-chip IP block and guaranteed to exist on
every board using
this SoC. If the RNG hardware is available, NuttX says it should be on by
default. See drivers/crypto/Kconfig:
config DEV_RANDOM
bool "Enable /dev/random"
default y
depends on ARCH_HAVE_RNG
---help---
Enable support for /dev/random provided by a hardware TRNG.
