* aspeed/hace: Accumulative mode supportedJoel Stanley2022-06-301-3/+3
| | | | | | | | | | | | | | While the HMAC mode is not modelled, the accumulative mode is. Accumulative mode is enabled by setting one of the bits in the HMAC engine command mode part of the register, so fix the unimplemented check to only look at the upper of the two bits.

| | | | | | | | | | | | | | | | | | | | | | | | | The aspeed ast2600 accumulative mode is described in datasheet ast2600v10.pdf section 25.6.4: 1. Allocating and initiating accumulative hash digest write buffer with initial state. * Since QEMU crypto/hash api doesn't provide the API to set initial state of hash library, and the initial state is already set by crypto library (gcrypt/glib/...), so skip this step. 2. Calculating accumulative hash digest. (a) When receiving the last accumulative data, software need to add padding message at the end of the accumulative data. Padding message described in specific of MD5, SHA-1, SHA224, SHA256, SHA512, SHA512/224, SHA512/256. * Since the crypto library (gcrypt/glib) already pad the padding message internally. * This patch is to remove the padding message which fed byguest machine driver.

* hw: Model ASPEED's Hash and Crypto EngineJoel Stanley2021-05-011-0/+389
The HACE (Hash and Crypto Engine) is a device that offloads MD5, SHA1, SHA2, RSA and other cryptographic algorithms. This initial model implements a subset of the device's functionality; currently only MD5/SHA hashing, and on the ast2600's scatter gather engine.
