A quick summary of what is included for those who don't feel like reading the spec:

  - Some miscellaneous bit twiddling instructions (rotate, permute, pack, ...) useful in various crypto schemes.
  - AES.
  - SHA2 (-256 and -512).
  - SM3 and SM4. 
  - Physical entropy source (with some variants to accommodate low profile variants)

The SM3/4 were unfamiliar to me - apparently it is a hash function & block cipher used in Chinese WiFi variant. Should I just assume this is backdoored?
