回复: [edk2-devel] [PATCH 1/1] MdePkg/BaseRngLibDxe: Add DXE_RUNTIME_DRIVER class to RngLib

[gaoliming]

I agree this library instance can be used for RUNTIME driver before boot to
OS. 

Can you let me know which runtime driver consumes it? And, please make sure
the consumer code runs in boot phase only. 

Thanks
Liming
