Hi Sami,

I've been looking through the design document again, and was wondering if the work I previously did will just slot in?

Were you thinking the "RngLib|RNDR" would go into ArmPkg (since = it's not
labeled as being in BaseRngLib)? Or would it still make sense to
refactor MdePkg/Library/BaseRngLib to support both x86 (using RDRAND)
and aarch64 (using RNDR)?
