+ARMv8 Crypto Poll Mode Driver
+================================
+
+This code provides the initial implementation of the ARMv8 crypto PMD.
+The driver uses ARMv8 cryptographic extensions to process chained crypto
+operations in an optimized way. The core functionality is provided by
+a low-level assembly code specific to all supported cipher and hash
+combinations.
+
+Features
+--------
+
+ARMv8 Crypto PMD has support for the following algorithm pairs:
+
+Supported cipher algorithms:
+* ``RTE_CRYPTO_CIPHER_AES_CBC``
+
+Supported authentication algorithms:
+* ``RTE_CRYPTO_AUTH_SHA1``
+* ``RTE_CRYPTO_AUTH_SHA256``
+* ``RTE_CRYPTO_AUTH_SHA1_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA256_HMAC``
+
+Installation
+------------
+
+To compile ARMv8 Crypto PMD, it has to be enabled in the config/common_base
+file. No additional packages need to be installed.
+The corresponding device can be created only if the following features
+are supported by the CPU:
+
+* ``RTE_CPUFLAG_AES``
+* ``RTE_CPUFLAG_SHA1``
+* ``RTE_CPUFLAG_SHA2``
+* ``RTE_CPUFLAG_NEON``
+
+Initialization
+--------------
+
+User can use app/test application to check how to use this PMD and to verify
+crypto processing.
+
+Test name is cryptodev_sw_armv8_autotest.
+For performance test cryptodev_sw_armv8_perftest can be used.
+
+Limitations
+-----------
+
+* Maximum number of sessions is 2048.
+* Only chained operations are supported.
+* AES-128-CBC is the only supported cipher variant.
+* Input data has to be a multiple of 16 bytes.

=========================================================
+* **Added armv8 crypto PMD.**
+
+ A new crypto PMD has been added, which provides combined mode cryptografic
+ operations optimized for ARMv8 processors. The driver can be used to enhance
+ performance in processing chained operations such as cipher + HMAC.
