Specification

• Latest Draft Scalar Crypto Specification (v0.9.1)
• Stable in asciidoc form now.
• Some consistency review feedback which will be applied in subsequent functional releases:
  
  • aes32* and sm4* encodings will change to remove the `rt` field.
  • Change aes64ks1i "rcon" immediate to "rnum".
  • Remove packu[w] since they aren't needed for our usecase of packing bytes into words. We can use other pack instructions.
  • Break Zbk into smaller units: (Zbkc: clmul*, Zbkx: xperm.*, Zbkb: everything else)
  • Entropy source changes, including configurable access to the entropy source from S mode.
