+NXP DPAA CAAM (DPAA_SEC)
+========================
+
+The DPAA_SEC PMD provides poll mode crypto driver support for NXP DPAA CAAM
+hardware accelerator.
+
+Architecture
+------------
+
+SEC is the SOC's security engine, which serves as NXP's latest cryptographic
+acceleration and offloading hardware. It combines functions previously
+implemented in separate modules to create a modular and scalable acceleration
+and assurance engine. It also implements block encryption algorithms, stream
+cipher algorithms, hashing algorithms, public key algorithms, run-time
+integrity checking, and a hardware random number generator. SEC performs
+higher-level cryptographic operations than previous NXP cryptographic
+accelerators. This provides significant improvement to system level performance.
+
+DPAA_SEC is one of the hardware resource in DPAA Architecture. More information
+on DPAA Architecture is described in :ref:`dpaa_overview`.
+
+DPAA_SEC PMD is one of DPAA drivers which interacts with QBMAN to create,
+configure and destroy the device instance using queue pair with CAAM portal.
+
+DPAA_SEC PMD also uses some of the other hardware resources like buffer pools,
+queues, queue portals to store and to enqueue/dequeue data to the hardware SEC.
+
+Implementation
+--------------
+
+SEC provides platform assurance by working with SecMon, which is a companion
+logic block that tracks the security state of the SOC. SEC is programmed by
+means of descriptors (not to be confused with frame descriptors (FDs)) that
+indicate the operations to be performed and link to the message and
+associated data. SEC incorporates two DMA engines to fetch the descriptors,
+read the message data, and write the results of the operations. The DMA
+engine provides a scatter/gather capability so that SEC can read and write
+data scattered in memory. SEC may be configured by means of software for
+dynamic changes in byte ordering. The default configuration for this version
+of SEC is little-endian mode.
+
+Features
+--------
+
+The DPAA PMD has support for:
+
+Cipher algorithms:
+
+* ``RTE_CRYPTO_CIPHER_3DES_CBC``
+* ``RTE_CRYPTO_CIPHER_AES128_CBC``
+* ``RTE_CRYPTO_CIPHER_AES192_CBC``
+* ``RTE_CRYPTO_CIPHER_AES256_CBC``
+* ``RTE_CRYPTO_CIPHER_AES128_CTR``
+* ``RTE_CRYPTO_CIPHER_AES192_CTR``
+* ``RTE_CRYPTO_CIPHER_AES256_CTR``
+
+Hash algorithms:
+
+* ``RTE_CRYPTO_AUTH_SHA1_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA224_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA256_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA384_HMAC``
+* ``RTE_CRYPTO_AUTH_SHA512_HMAC``
+* ``RTE_CRYPTO_AUTH_MD5_HMAC``
+
+AEAD algorithms:
+
+* ``RTE_CRYPTO_AEAD_AES_GCM``
+
+Supported DPAA SoCs
+--------------------
+
+* LS1046A/LS1026A
+* LS1043A/LS1023A
+
+Limitations
+-----------
+
+* Chained mbufs are not supported.
+* Hash followed by Cipher mode is not supported
+* Only supports the session-oriented API implementation (session-less APIs are not supported).
+
+Prerequisites
+-------------
+
+DPAA_SEC driver has similar pre-requisites as described in :ref:`dpaa_overview`.
+The following dependencies are not part of DPDK and must be installed separately:
+
+* **NXP Linux SDK**
+
+  NXP Linux software development kit (SDK) includes support for the family
+  of QorIQ® ARM-Architecture-based system on chip (SoC) processors
+  and corresponding boards.
+
+  It includes the Linux board support packages (BSPs) for NXP SoCs,
+  a fully operational tool chain, kernel and board specific modules.
+
+  SDK and related information can be obtained from:  `NXP QorIQ SDK  <http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX>`_.
+
+* **DPDK Extras Scripts**
+
+  DPAA based resources can be configured easily with the help of ready scripts
+  as provided in the DPDK Extras repository.
+
+  `DPDK Extras Scripts <https://github.com/qoriq-open-source/dpdk-extras>`_.
+
+Currently supported by DPDK:
+
+* NXP SDK **2.0+**.
+* Supported architectures:  **arm64 LE**.
+
+* Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+Basic DPAA config file options are described in :ref:`dpaa_overview`.
+In addition to those, the following options can be modified in the ``config`` file
+to enable DPAA_SEC PMD.
+
+Please note that enabling debugging options may affect system performance.
+
+* ``CONFIG_RTE_LIBRTE_PMD_DPAA_SEC`` (default ``n``)
+  By default it is only enabled in defconfig_arm64-dpaa-* config.
+  Toggle compilation of the ``librte_pmd_dpaa_sec`` driver.
+
+* ``CONFIG_RTE_LIBRTE_DPAA_SEC_DEBUG_INIT`` (default ``n``)
+  Toggle display of initialization related driver messages
+
+* ``CONFIG_RTE_LIBRTE_DPAA_SEC_DEBUG_DRIVER`` (default ``n``)
+  Toggle display of driver runtime messages
+
+* ``CONFIG_RTE_LIBRTE_DPAA_SEC_DEBUG_RX`` (default ``n``)
+  Toggle display of receive fast path run-time message
+
+* ``CONFIG_RTE_DPAA_SEC_PMD_MAX_NB_SESSIONS``
+  By default it is set as 2048 in defconfig_arm64-dpaa-* config.
+  It indicates Number of sessions to create in the session memory pool
+  on a single DPAA SEC device.
+
+Installations
+-------------
+To compile the DPAA_SEC PMD for Linux arm64 gcc target, run the
+following ``make`` command:
+
+.. code-block:: console
+
+   cd <DPDK-source-directory>
+   make config T=arm64-dpaa-linuxapp-gcc install
