From: Nipun Gupta <nipun.gu...@nxp.com>
With DMA devices supported as a separate flavor of devices,
the DPAA2 QDMA driver is moved in the DMA devices.
This change removes the DPAA2 QDMA driver from raw devices.

-NXP DPAA2 QDMA Driver
-=====================
-
-The DPAA2 QDMA is an implementation of the rawdev API, that provide means
-to initiate a DMA transaction from CPU. The initiated DMA is performed
-without CPU being involved in the actual DMA transaction. This is achieved
-via using the DPDMAI device exposed by MC.
-
-More information can be found at `NXP Official Website
-<http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/qoriq-arm-processors:QORIQ-ARM>`_.
-
-Features
---------
-
-The DPAA2 QDMA implements following features in the rawdev API;
-
-- Supports issuing DMA of data within memory without hogging CPU while
- performing DMA operation.
-- Supports configuring to optionally get status of the DMA translation on
- per DMA operation basis.
-
-Supported DPAA2 SoCs
---------------------
-
-- LX2160A
-- LS2084A/LS2044A
-- LS2088A/LS2048A
-- LS1088A/LS1048A
-
-Prerequisites
--------------
-
-See :doc:`../platform/dpaa2` for setup information
-
-- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup
the basic DPDK environment.
-
-.. note::
-
- Some part of fslmc bus code (mc flib - object library) routines are
- dual licensed (BSD & GPLv2).
-
-
-Enabling logs
--------------
-
-For enabling logs, use the following EAL parameter:
-
-.. code-block:: console
-
- ./your_qdma_application <EAL args> --log-level=pmd.raw.dpaa2.qdma,<level>
-
-Using ``pmd.raw.dpaa2.qdma`` as log matching criteria, all Event PMD logs can
be
-enabled which are lower than logging ``level``.
-
-
-Initialization
---------------
-
-The DPAA2 QDMA is exposed as a vdev device which consists of dpdmai devices.
-On EAL initialization, dpdmai devices will be probed and populated into the
-rawdevices. The rawdev ID of the device can be obtained using
-
-* Invoking ``rte_rawdev_get_dev_id("dpdmai.x")`` from the application
- where x is the object ID of the DPDMAI object created by MC. Use can
- use this index for further rawdev function calls.
-
-Platform Requirement
-~~~~~~~~~~~~~~~~~~~~
-
-DPAA2 drivers for DPDK can only work on NXP SoCs as listed in the
-``Supported DPAA2 SoCs``.
