The Intel Keem Bay SoC has an Offload Crypto Subsystem (OCS) featuring a crypto engine for accelerating AES/SM4 operations. This driver adds support for such hardware thus enabling hardware acceleration for the following transformations on the Intel Keem Bay SoC: - ecb(aes), cbc(aes), ctr(aes), cts(cbc(aes)), gcm(aes) and cbc(aes); supported for 128-bit and 256-bit keys. - ecb(sm4), cbc(sm4), ctr(sm4), cts(cbc(sm4)), gcm(sm4) and cbc(sm4); supported for 128-bit keys. The driver passes crypto manager self-tests, including the extra tests (CRYPTO_MANAGER_EXTRA_TESTS=y). Note: this driver is different from the Keem Bay OCS HCU driver previously submitted. Keem Bay OCS HCU provides hardware-accelerated ahash, while Keem Bay AES/SM4 (i.e., this driver) provides hardware-accelerated skcipher and aead.
