BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4441 The EFI_RNG_PROTOCOL can rely on the RngLib. The RngLib has multiple implementations, some of them are unsafe (e.g. BaseRngLibTimerLib). To allow the RngDxe to detect when such implementation is used, a GetRngGuid() function is added in a following patch. Prepare GetRngGuid() return values and add a gEfiRngAlgorithmArmRndr to describe a Rng algorithm accessed through Arm's RNDR instruction. [1] states that the implementation of this algorithm should be compliant to NIST SP900-80. The compliance is not guaranteed.
