[dpdk-dev] [PATCH v4 00/21] NXP DPAA2 FSLMC Bus driver

[Hemant Agrawal <hemant.agrawal@nxp.com>]

(This patches has been split from DPAA2 PMD v8 series [1] as per
comments received on ML [2].)

For V3 - please check at [3].

The patchset introduces NXP’s QorIQ-Layerscape DPAA2 Architecture based
fsl-mc bus driver. This version of the driver supports NXP LS208xA,
LS204xA and LS108x family of Network SoCs.

This driver is base for DPAA2 based PMD to be introduced in later patches.
It will be used by dpaa2 net, crypto, event & other devices.
The details description of this bus along with PMD is part of later patch
sets for introducing the NXP DPAA2 PMD.

There are 3 main components of the FSLMC bus which enable the access to
DPAA2 devices from userspace:
1) QBMAN hardware: Which enables application lock-less access to hardware
   queues and buffers.
2) MC or Management Complex: Layer between Userspace and elements on the
   FSLMC bus. This layer exposes underlying hardware as 'objects' and
   allows for their configuration. Some of the key objects exposed are:
    - DPNI, which refers to the network interface object.
    - DPBP, which refers to HW based memory pool object
    - DPIO, refers to processing context for accessing QBMAN
3) Portal: For accessing the hardware objects exposed by MC, a continuous
   mapped area is available in form of objects.

This patchset introduces the above components.

Future Changes/Caveats:

1) VFIO code for fsl-mc bus is different than eal-vfio code for pci bus.
   This need to be re-worked to make possible re-use of the existing code.
