==========================================
Random Number Generator Synchronous driver
==========================================

Random Number Generator (RAND) generates a sequence of numbers that can not
be reasonably predicted better than by a random chance.

In some implementation cases, seed is required for the Random Number Generator
to generate random numbers. rand_sync_set_seed is used to update the seed.
If it's actually not required by the generator implementation, the function just
returns ERR_UNSUPPORTED_OP.
