[PATCH v3 2/3] hwrng: stm32 - add support for STM32 HW RNG

Add support for STMicroelectronics STM32 random number generator. The config value defaults to N, reflecting the fact that STM32 is a very low resource microcontroller platform and unlikely to be targeted by any "grown up" defconfigs. Signed-off-by: Daniel Thompson
