[edk2-devel] [PATCH 0/3] MdePkg, SecurityPkg: Update BaseRngLib and RngDxe to support ARMv8.5 FEAT_RNG

[Rebecca Cran]

This is the RngLib|RNDR implementation from page 11 of the "Proposed
update to RNG implementation" presentation from Ard and Sami.

The presentation can be found at:
https://edk2.groups.io/g/devel/files/Designs/2021/0116/EDKII%20-%20Proposed%20update%20to%20RNG%20implementation.pdf

Rebecca Cran (3):
  MdePkg/BaseLib: Add support for ARMv8.5 RNG instructions
  MdePkg: Refactor BaseRngLib to support AARCH64 in addition to X86
  SecurityPkg: Add support for RngDxe on AARCH64
