<p>I've written a tiny tool to visualize the randomness, cause I've read that this is a valid method of analyzing them.<br>
This is what the dumps look like. Each rectangle is one dump and consists of 100 columns (the random numbers of this dump) and 32 rows (bits true in number).<br>
The top row of rectangles are the dumps from master (nrf51dk  nrf52832mdk  nrf52840dk  nrf52840mdk  nrf52dk) and the bottom row are the dumps from your PR.</p>

<p>I think this looks random enough in both cases.</p>
