title: ASPEED HACE hash and crypto Hardware Accelerator Engines

maintainers:

description: |
  The Hash and Crypto Engine (HACE) is designed to accelerate the throughput
  of hash data digest, encryption, and decryption. Basically, HACE can be
  divided into two independently engines - Hash Engine and Crypto Engine.
