312b82f275 bus/fslmc: support for parallel Rx DQ requests
DPAA2 hardware support the option to configure
multiple memories for Rx recv buffer (DPAA2-DQRR).
Each Rx request executing is called as 'DQ' request.
This patch adds routines to get information w.r.t each DQ request.

9464dbe9c9 net/dpaa2: stop using software annotation
The DPAA2 driver is not using the DPAA2 frame descriptor
software annotation area. This patch reduces the
PTA length to zero and adjust the RX Buffer Layout
accordingly.

a0d5c9caf0 bus/fslmc: add frame queue based dq storage
This patch adds generic functions for allowing dq storage
for the frame queues.
As the frame queues are common resource for different drivers
this is helpful.

5374e50f10 bus/fslmc: add dpio portal driver
The portal driver is bound to DPIO objects discovered on the fsl-mc bus and
provides services that:
- allow other drivers, such as the Ethernet driver, to enqueue and dequeue
  frames for their respective objects

A system will typically allocate 1 DPIO object per CPU to allow queuing
operations to happen simultaneously across all CPUs.

70e58cf74c bus/fslmc: support VFIO
Add support for using VFIO for dpaa2 based fsl-mc bus.

There are some differences in the way vfio used for fsl-mc bus
from the eal vfio.
 - The scanning of bus for individual objects on the basis of
   the DPRC container.
 - The use and mapping of MC portal for object access

With the evolution of bus model, they can be further aligned with
eal vfio code.

3af733ba8d bus/fslmc: introduce MC object functions
This patch introduces the DPAA2 MC(Management complex Driver).

This is a minimal set of low level functions to send and
receive commands to the fsl-mc. It includes support for basic
management commands and commands to manipulate MC objects.

This is common to be used by various DPAA2 PMDs. e.g.net, crypto
and other drivers.

This is a low level library also used in kernel.

531b17a780 bus/fslmc: add QBMAN driver to bus
QBMAN, is a hardware block which interfaces with the other
accelerating hardware blocks (For e.g., WRIOP) on NXP's DPAA2
SoC for queue, buffer and packet scheduling.

This patch introduces a userspace driver for interfacing with
the QBMAN hw block.

The qbman-portal component provides APIs to do the low level
hardware bit twiddling for operations such as:
  -initializing Qman software portals
  -building and sending portal commands
  -portal interrupt configuration and processing

This same/similar code is used in kernel and compat file is used
to make it working in user space.
