Kindly let me know your feedback or if you have any queries.
The ARMv8.5 RNDRRS instruction appears to be missing from the diagram on
page 11 - it has RngLib|RNDR, which is listed under PRNG, but RNDRRS
returns a true random number. From the Arm ARM:
"Returns a 64-bit random number which is reseeded from the True
Random Number source immediately before the read of the random number."
