	  Support for Intel Keem Bay Offload and Crypto Subsystem (OCS) AES and
	  SM4 cipher hardware acceleration for use with Crypto API.

	  Provides HW acceleration for the following transformations:
	  cbc(aes), ctr(aes), ccm(aes), gcm(aes), cbc(sm4), ctr(sm4), ccm(sm4)
	  and gcm(sm4).

	  Optionally, support for the following transformations can also be
	  enabled: ecb(aes), cts(cbc(aes)), ecb(sm4) and cts(cbc(sm4)).

	  Elliptic Curve Cryptography (ECC) hardware acceleration for use with
	  Crypto API.

	  Provides OCS acceleration for ECDH-256 and ECDH-384.

	  Say Y or M if you are compiling for the Intel Keem Bay SoC. The
	  module will be called keembay-ocs-ecc.

	  If unsure, say N.

	  Support for Intel Keem Bay Offload and Crypto Subsystem (OCS) Hash
	  Control Unit (HCU) hardware acceleration for use with Crypto API.

	  Provides OCS HCU hardware acceleration of sha256, sha384, sha512, and
	  sm3, as well as the HMAC variant of these algorithms.

	  Say Y or M if you're building for the Intel Keem Bay SoC. If compiled
	  as a module, the module will be called keembay-ocs-hcu.

	  If unsure, say N.

config CRYPTO_DEV_KEEMBAY_OCS_HCU_HMAC_SHA224
	bool "Enable sha224 and hmac(sha224) support in Intel Keem Bay OCS HCU"
	depends on CRYPTO_DEV_KEEMBAY_OCS_HCU
	help
	  Enables support for sha224 and hmac(sha224) algorithms in the Intel
	  Keem Bay OCS HCU driver. Intel recommends not to use these
	  algorithms.

	  Provides OCS HCU hardware acceleration of sha224 and hmac(224).

	  If unsure, say N.
