This is the cover letter for patchset [1]. First, do not restrain the STM32 RNG driver to the MPU series.
The STM32MP13x platforms have a RNG hardware block that supports customization, a conditional reset sequences that allows to recover from certain situations and a configuration locking mechanism. This series adds support for the mentionned features. Note that the hardware RNG can and should be managed in the secure world for this platform, hence the rng not being default enabled on the STM32MP135F-DK board.
