David Gstir 3d16af0b4c crypto: mxs-dcp: Add support for hardware-bound keys ... DCP (Data Co-Processor) is able to derive private keys for a fused random seed, which can be referenced by handle but not accessed by the CPU. Similarly, DCP is able to store arbitrary keys in four dedicated key slots located in its secure memory area (internal SRAM). These keys can be used to perform AES encryption. Expose these derived keys and key slots through the crypto API via their handle. The main purpose is to add DCP-backed trusted keys. Other use cases are possible too (see similar existing paes implementations), but these should carefully be evaluated as e.g. enabling AF_ALG will give userspace full access to use keys. In scenarios with untrustworthy userspace, this will enable en-/decryption oracles.
