In our program, OpensslLib was utilized. Nevertheless, the random number could not be successfully obtained by the "GetRandomNumber64" (in OpensslLib/OpensslStub/rand_pool.c). It appears that our SoC (AmpereAltra) is not supported, based on our investigation (failed at https://github.com/tianocore/edk2/blob/master/MdePkg/Library/BaseRngLib/BaseRng.c#L90). Exists a solution to this problem or any alternatives?
